In controlled environment studies, the optimum average daily temperature for leaf growth for E. novogranatense var. novogranatense was found to be around 27 °C (81 °F), whereas leaf growth was generally higher at photosynthetic photon flux densities (PPFD) of 250 or 400 micromol per meter square per second than at 155 micromol per meter ...
The plants thrive best in hot, damp and humid locations, such as the clearings of forests; but the leaves most preferred are obtained in drier areas, on the hillsides. The leaves are gathered from plants varying in age from one and a half to upwards of forty years, but only the new fresh growth is harvested.
Chemical structure of cocaine. The biosynthesis of cocaine has long attracted the attention of biochemists and organic chemists. This interest is partly motivated by the strong physiological effects of cocaine, but a further incentive was the unusual bicyclic structure of the molecule. The biosynthesis can be viewed as occurring in two phases ...
By the 17th century, when those buried in the crypt would have lived, Milan (then a possession of Spain) was a major importer of exotic plants, especially from the Americas, so cocaine could’ve ...
A leaf area index (LAI) expresses the leaf area per unit ground or trunk surface area of a plant and is commonly used as an indicator of the growth rate of a plant. LAI is a complex variable that relates not only to the size of the canopy, but also to its density, and the angle at which leaves are oriented in relation to one another and to ...
Cocaine (from French cocaïne, from Spanish coca, ultimately from Quechua kúka) [13] is a tropane alkaloid that acts as a central nervous system (CNS) stimulant.As an extract, it is mainly used recreationally and often illegally for its euphoric and rewarding effects.
