"the possibility that tobacco GST glands may form some nicotine has apparently not been tested directly." i doubt whether this statement is wholly true, tobacco industry keeping secrets? anyone ever tried extraction on tobacco? edit: btw be careful with nicotine it's pretty poisonous in very small amounts

these type of studies i think have huge benifits relating to medical use of THC just a sad shame that any physical testing of our favourite trichome is still relegated to the "underworld."

a new formula to throw into the productivity mix

"Quantitative and qualitative aspects of cannabinoid
accumulation are often confused as pointed out by Hil-
(2002) in a critical comment on Sytnik and Stel-
mah (1999). To specify the target of the current article
is adequate to express the yield of a certain canna-
binoid per crop area unit as a complex trait,

CYn x DM x Pflor x Ctot x PCn , (1)

where CYn is the yield of cannabinoid, n (grams per
square meter); DM is the total amount of dry, above-
biomass (grams per square meter); Pflor is the
proportion of inflorescence leaves and bracts
(grams per gram); Ctot is the total cannabinoid content
in the inflorescence leaves and bract fraction (grams
per gram); and PCn is “purity,” the proportion of canna-
binoid n in the total cannabinoid fraction (grams per
1974). Later, Fournier and Paris (1980) assumed that gram).
The first three components determining the canna-
binoid yield are probably polygenic traits not related to
specific metabolic pathways and are heavily affected by
environment. In contrast, the latter term of Equation
1, the proportion of a certain cannabinoid in the total
cannabinoid fraction, depends strictly on the metabolic
pathways followed by the plant to convert common preof
cursors into specific end products. The focus in this
article is on the proportions of the two most commonly
found and abundant cannabinoids, CBD and THC, and
restricts the definition of chemotype to the ratio of
CBD/THC, with both terms expressed as percentage of
the inflorescence dry weight."
