In earlier research, induction of hermaphroditism in marijuana plants was achieved experimentally by applications of gibberellic acid (Heslop-Harrison, 1956, 1957; Ram and Jaiswal, 1970, 1972, 1974; Galoch, 1978; Rosenthal, 1991; United Nations Office on Drugs and Crime [UNOCD], 2009). Other studies showed that male and female flower ratios in marijuana plants could be altered by applications of chemicals such as 2-chloroethanephosphonic acid, aminoethoxyvinylglycine, silver nitrate, silver thiosulfate, or cobalt chloride (Ram and Jaiswal, 1970, 1972; Ram and Sett, 1981). Silver nitrate inhibits ethylene action in plants (Kumar et al., 2009) and was reported to increase male sex expression in marijuana, cucumber and gourd plants (Atsmon and Tabbak, 1979; Ram and Sett, 1982; Stankovic and Prodanovic, 2002). In a recent study, applications of silver thiosulfate induced male flower formation on genetically female hemp plants (Lubell and Brand, 2018). These findings demonstrate that changes in growth regulator levels in treated plants can impact hermaphroditic flower formation.

Physical or chemical stresses can also have a role in inducing staminate flower development on female plants of marijuana. For example, external environmental stresses, e.g., low photoperiods and reduced temperatures in outdoor production, were reported to increase staminate flower formation (Kaushal, 2012). Some plants formed hermaphroditic flowers when female plants were exposed to extended periods of darkness early during growth or during altered photoperiods during the flowering stage, although the exact conditions were not described (Rosenthal, 1991, 2000). Such stress factors could affect internal phytohormone levels, such as auxin:gibberellin ratios (Tanimoto, 2005), which could in turn trigger hermaphroditic flower formation in marijuana plants. In Arabidopsis plants, auxin, gibberellin and ethylene interact with jasmonic acid (JA) to alter stamen production (Song et al., 2013, 2014). Consequently, jasmonic-acid deficient mutant Arabidopsis plants exhibited male sterility, with arrested stamen development and non-viable pollen (Jewell and Browse, 2016) while JA treatment restored stamen development in these mutants. In marijuana plants, environmental stress factors which enhance JA production could potentially promote hermaphroditic flower formation but this requires further study. Lability of sex expression may offer advantages in promoting seed formation in hermaphroditic plants subject to environmentally stressful conditions (Ainsworth, 2000).

In the present study, pollen germination and germ tube growth were observed in samples of hermaphrodite flowers and pollen transfer from male flowers to stigmas of female flowers showed germination in situ followed by germ tube growth and penetration of the stigmatic papilla. Small and Naraine (2015) and Small (2017) showed pollen grains attached to stigmatic papillae but the germination and penetration process was not described. We observed a row of bulbous trichomes forming along the stomium on the anthers in staminate flowers and in hermaphroditic flowers, confirming earlier descriptions by Potter (2009) and Small (2017) for staminate flowers. The function of these trichomes is unknown. The findings described here are the first to demonstrate viable pollen production and anther morphology in hermaphroditic flowers in marijuana.

Discussion​

Overall, STS at 3 mm was the most effective treatment for producing the greatest number of male flowers on female hemp plants. Green (2015) suggested that female hemp plants can be masculinized using a single foliar spray of 0.3 mm STS, but did not provide any information about the percent conversion to male flowers. We did not find three foliar sprays of 0.3 mm STS to be as effective for producing male flower formation as three foliar sprays of 3 mm STS. However, there may be specific strains, such as CBD hemp A, which produce primarily male flowers with STS concentrations less than 3mm.

Silver thiosulfate has been used to extend the vase life of cut flowers by blocking the effect of ethylene (Farnham et al., 1981; Veen and van de Geijn, 1978). A similar action of ethylene blocking by STS is likely responsible for the production of male flowers on female hemp plants in our study. It is generally believed that ethylene blocking is extended when a series of sprays of STS is used compared with a single spray of STS (Reid et al., 1980). It may be possible to induce male flowers on genetically female hemp using other ethylene perception inhibiting chemicals such as 1-methylcyclopropene.

Mohan Ram and Sett (1982), using 25 to 100 µg STS applied directly to the growing shoot tip of female hemp plants, were able to produce male flowers. However, they also noted severe necrosis on young leaves covering shoot tips and suspended apical growth for 20 to 25 d before lateral budbreak and subsequent flower formation. In comparison, we did not observe any plant phytotoxicity or delay in flower development. Furthermore, we were able to achieve 95% to 100% conversion to male flowers for all hemp strains, whereas Mohan Ram and Sett (1982) reported ≈60% to 80% conversion.

Producers and breeders should be able to masculinize female hemp plants routinely by using short-day conditions of ≈8 h and three foliar sprays of 3 mm STS at weekly intervals. We suspect that this method will be applicable for a broad range of genetically diverse hemp genotypes. Pollen produced by male flowers on genetically female plants can be used to produce all-female seed, but growers and breeders should be aware that pollen output may be reduced compared with pollen output from genetically male plants.

Summary​

Apical application of silver nitrate (AgNO3; 50 and 100 μg per plant) and silver thiosulphate anionic complex (Ag(S2O3)3−2; STS; 25, 50 and 100 μg per plant) to female plants of Cannabis sativa induced the formation of reduced male, intersexual and fully altered male flowers on the newly formed primary lateral branches (PLBs); 10 μg per plant of AgNO3 was ineffective and 150 μg treatment proved inhibitory. A maximum number of fully altered male flowers were formed in response to 100 μg STS. The induced male flowers produced pollen grains that germinated on stigmas and effected seed set. Silver ion applied as STS was more effective than AgNO3 in inducing flowers of altered sex. The induction of male flowers on female plants demonstrated in this work is useful for producing seeds that give rise to only female plants.

Results​

We show that the life cycle of cannabis can be fully completed in tissue culture; plantlets readily produce inflorescences and viable seeds in vitro. Our findings highlight the superior performance of DKW medium with 2% sucrose in a filtered vessel and emphasize the need for low light intensity during flower induction to optimize production. The improved performance in filtered vessels suggests that plants conduct photosynthesis in vitro, highlighting the need for future investigations into the effects of forced ventilation to refine this system. All tested lines readily developed inflorescences upon induction, with a 100% occurrence rate, including male flowering. We revealed the non-dehiscent trait of in vitro anthers, which is advantageous as it allows for multiple crosses to be conducted in vitro without concerns about cross-contamination.

Floral reversion​

Floret number significantly affected the percent reversion of explants to the vegetative state in both the BAP and mT experiments (Table 1 and Table 2). In both experiments, pairs were approximately three times more likely to revert than single florets. The treatment average for all BAP treated explants (0 μM to 10 μM) found that 55% of floret pairs reverted compared to only 18% of single floret (p < 0.0001). The BAP treatment with the highest percentage reversion was 1 μM BAP using pairs of florets which achieved an average of 69% reversion (Fig. 2A). A similar trend was observed in mT treated of floral explants of cv. U91, where pairs of florets showed approximately 2.5 times higher rate of reversion (70% vs 28%; p < 0.0001) between the singles and pairs of floret treatment averages. Treatment of pairs of florets at 1 and 10 μM mT achieved the highest percentage reversion with 81% of florets reverting (Fig. 2B). While the percent reversion was significantly affected by the floret number, the number of shoots produced per explant was not significantly affected by any of the fixed effects, with each treatment producing between 1.5 and < 2 vegetative shoots per responding explant. Each flowering in vitro plant produced an average of 24 ± 6 healthy florets (or 12 pairs) for use in the experiments.

​

Everyone loves a good cooler. They are essential for keeping food and drinks cold, whether at home or on the go. As the temperature outside starts to rise, cooler-lovers start to think about cooler options.
Besides electric coolers, solar-powered coolers are gaining popularity as an eco-friendly cooler option. Read this guide to learn more about solar power, the advantages of solar power coolers, and how you can choose the best solar cooler for your needs.

What Is A Solar Powered Cooler?​

Solar powered coolers are the latest innovation in affordable, eco-friendly cooling. They provide a cool environment using energy directly from solar panels or a lithium battery.
These solar-powered units are economical to use and can be charged with a power bank, a solar panel, or a portable power source such as a Jackery or power bank.
The solar power is transferred to the cooler when in use, and the power bank can be disconnected and charged directly from the solar panel.
The solar powered cooler is great for taking meals and beverages on picnics, to the beach, in an RV, or on a boat. They are also handy for those who want to help the environment but don't want to compromise on their favorite cold snacks and meals.

Types Of Solar Powered Coolers​

These coolers usually have a capacity of around 30 to 50 quarts and can be powered by a single solar panel.

How To Choose The Best Solar Powered Cooler?​

When shopping for a solar-powered cooler, there are a few factors to consider.

Capacity​

Solar cooler has a tank capacity of 35L, which means it can cool air efficiently and effectively. It works by converting dry air into cool air using moist cooling pads.
A solar cooler eliminates the consumption of AC power and is economically sustainable as it only requires solar power to function. Additionally, solar cooler provides economic benefits as it saves on the cost of operating an AC cooling system.

Power Output​

A solar cooler works by converting the radiant energy from the sun into electricity, which is then stored in a battery. It runs on solar power to generate power for cooling.
The solar cooler works by converting the radiant energy from the sun into cold air that is pushed through moist cooling pads. This process results in evaporation and a drop in temperature.
It dissipates heat from food and beverages quickly and efficiently, making it a great way to refrigerate items as easily as possible.

Insulation​

Solar-powered coolers use a simple evaporative cooling principle to lower the temperature of the cooler. They do so by using solar panels to convert the radiant energy from the sun into electricity, which is stored in a battery.
This stored energy can then be used to power the cooler. To ensure the cooler can maintain its temperature, solar-powered coolers must be insulated.
This insulation helps to keep heat in a while, also preventing the solar panel from overheating. Insulation of solar-powered coolers is important to maintain its efficiency and performance.

Temperature Control​

A solar cooler uses a special cooling technology that allows it to cool the air quickly and efficiently. It works by absorbing solar energy and using it to heat a liquid, called the coolant, which is then transferred to the air inside the cooler.
This process causes the coolant to become cooler and faster than the surrounding air, leading to a drop in temperature. Solar-powered coolers are generally installed near solar panels or batteries that provide power when the sun is shining.
The solar energy stored in these sources is used to power the cooler when it is not in use. The solar-powered cooler can acquire a working electrical current from a wall outlet (120 voltage or AC), a 12v outlet (DC), or a portable power station battery.

Durability​

A solar cooler is a portable cooler that uses solar power to lower its temperature. They are made of durable materials such as iron, making them strong and sturdy enough to handle the abuses of daily use.
These coolers from Amazon use a simple evaporative cooling principle to reduce the temperature of their contents quickly and efficiently. They are powered by energy produced directly from solar panels or battery, making them efficient and cost-effective.

Portability​

When shopping for a portable solar cooler, consider the wattage power (W) required to keep the cooler running at optimal performance.
Additionally, look for solar powered cooler with a solar table to recharge the cooler.
Also, ensure the tank capacity is suitable for your needs. Additionally, consider the brand, motor speed and water inlet when selecting a solar cooler.
Portable coolers can be powered by solar power or 12v/120v power, making them versatile and dependable for outdoor applications.

The cooler from Danish Technological Institute is an efficient solar-powered fridge without built-in battery; it requires only sunlight to operate.

Price​

Picking the best solar cooler can be a challenge. There are several factors to consider, such as price, wattage, and features. When shopping for a solar cooler from Amazon , consider the wattage of the cooler's load and solar power.
Additionally, look for coolers with tank capacity and a material that will not absorb moisture from the ice.

How To Install The Solar Powered Cooler?​

Unpack The Cooler​

A solar cooler is an ice-free alternative to traditional coolers. Instead, solar cooler uses solar energy to keep food and drinks cold without the need for ice.
This can make it a convenient choice for outdoor activities or camping where there is limited access to a freezer. It's also an affordable and environmentally friendly way to stay healthy and enjoy food and drink, hot or cold, without taking up valuable space in the fridge or freezer.
Before unpacking the solar cooler at your camping trip, check that the electrical components have not come in contact with water.

Charge The Battery​

Solar panels or a battery charger can power a solar cooler. For solar-powered coolers, energy must be generated directly from solar panels or a battery to power the cooler.
To power the cooler, portable power stations, like a Jackery or a power bank, can be used. To charge the cooler's lithium-ion battery, solar panels can be used to produce the DC current directly.
In addition to solar panels, rechargeable batteries can also be used to store solar energy and then provide power during peak hours when sunlight is unavailable.

Place The Solar Panel​

To maximize the solar panel's efficiency, it must be placed in direct sunlight. Moreover, it must be securely fastened to prevent it from getting damaged by wind or other elements.
Additionally, the solar panel should be at an angle that will receive the most sunlight throughout the day.

Connect The Solar Panel​

To connect your solar cooler to the grid, you need to connect the solar panel to a power source. Depending on the cooler's power requirements, you can use a solar panel or a portable power station.
Additionally, solar coolers use DC current generated by solar panels and are directly connected to the cooler's internal components. The solar panel converts sunlight into DC current, which is directly used by the cooler.
A backup battery is charged by the solar panel and used during night times or when there isn't sufficient sunlight for the cooler to operate.

Use The Cooler​

Solar powered coolers are an energy-efficient cooling solution that work by pulling hot, dry air through moist cooling pads. They are available in a range of sizes and cost-points, making them a great choice for cooling off during the summer months.
These coolers operate by acquiring their electrical current from wall outlets or portable power stations, making them easy to install and operate. Solar powered coolers are effective at maintaining comfortable temperature levels within a spaces, making them an attractive choice for offices and other indoor locations.

Maintenance Tips For Solar Powered Cooler​

Clean The Cooler Regularly​

Coolers are a great way to keep your food and drinks cold. However, they need to be regularly cleaned to stay sanitary and in good working condition.
If you are cleaning a solar cooler, be sure to use a damp cloth to wipe off the outside of the cooler. Use warm soapy water and a cleaning brush to clean the inside of the cooler.
After cleaning, make sure to dry it out thoroughly. To maintain your cooler, regularly check for signs of wear and replace the seals if necessary.

Keep The Solar Panels Clean​
