Pot leaf phyllotaxy
According to the quality phyllotaxy (the arrangement of leaves on a plant stem), cannabis leaves square measure compound (with multiple leaflets, as hostile straightforward, wherever one leaf grows from the stem) and decussate-opposite instead of an alternate.Opposite leaves emerge in pairs, one either side of the stem, with a transparent vertical area between the leaf pairs. Decussate leaves square measure opposite, however, every new leaf try is at a right angle to the last try. Alternate leaves emerge from the stem on an individual basis, swapping sides because the vertical height will increase.
Although cannabis leaves square measure sometimes decussate, because the plant prepares to flower the leaves might begin to emerge in the associate alternate pattern. curiously, rejuvenated cannabis plants demonstrate alternate phyllotaxy.
Experiments with hemp showed that early-planted specimens, that patterned in low light-weight conditions however failed to die, began to place out new alternate leaf growth once hours of daylight exaggerated. The initial new growth was straightforward instead of compound, and as new growth continuing, the quantity of leaflets bit by bit exaggerated.
There is some proof that this development results in the vegetative growth of greatly exaggerated vigor, though the genetic processes accountable aren’t totally understood. it’s thought that the evolution of opposite-decussate phyllotaxy occurred relatively recently, from the associate alternate-leaved ascendant, which the genes dominant the decussate phyllotaxy ‘switch off’ round the time of inflorescence.
Leaf variations between the 3 main taxon
Putting aside the eccentricities of cannabis leaf growth for an instant, allow us to take a glance at the variations between the 3 main taxon of cannabis. C. sativa leaves square measure long and slender, typically with pronounced serrations, giving the leaves a jagged, nearly high look. The coloration of sativa leaves ranges from bright, lime inexperienced to blackish-green at the darkest. the biggest leaves willtypically have up to 13 leaflets.
