Hello,
I have read of cold tolerances of up to -8°C in some cases (northern), and other cases in which they do not support below 1°C. Apart from the selection by aromas and flavors, or by potency, colors, or chemo-types. Does anyone know/has any experience, knowledge, literature (there is little about Cannabis) about breeding towards resistance to cold and drought (as a whole), thinking in an Alpine environment, approx. above 3.000 m.a.s.l.? I have read quite a bit of literature about how alpine and alpine plants adapted to those areas (usually cold and dry), but most of it happened due to environmental causes over thousands of years. There are some patterns as the elevation increases, such as dwarfing and expansion of the radius above the ground (prostrate/cushion-plants), or the decrease in the total area and rounding of the leaves, to avoid water loss. There is also an increase in the density of trichomes, due to the increase in UV radiation. But this occurs in plants adapted thousands of years to these environments.
-Being this species so plastic:
Has anyone tried or has records of crops/breeding in alpine or high alpine areas (where there are no trees on the hills)
Or also in very cold areas outside, where temperatures are below zero degrees Celsius?
Another interesting thing is that in some of these alpine places, these adapted plants living there are (≈50% day-neutral and ≈%50 photo-periods)
Thanks!
Here is an example of a characterization of those mountain environments, with photos, precipitations and temperature records (https://link.springer.com/article/10.1007/s00035-018-0202-9)
