The pyrimidine, 2-thiouracil, partly annuls the effect of photoperiodic induction in the short-day plant, Cannabis sativa L., when it is supplied at the onset of the dark period in quantities of 15-30 microg per plant. This treatment also produces aberrations in cellular differentiation in the

Hemp (Cannabis sativa L.) is a bast-fiber crop well-known for the great potential to produce sustainable fibers. Nevertheless, hemp fiber quality is a complex trait, and little is known about the phenotypic variability and heritability of fiber quality traits in hemp. The aim of this study is

Plants synthesize an astonishing diversity of isoprenoids, some of which play essential roles in photosynthesis, respiration, and the regulation of growth and development. Two independent pathways for the biosynthesis of isoprenoid precursors coexist within the plant cell: the cytosolic mevalonic

Cannabis sativa trichomes are glandular structures predominantly responsible for the biosynthesis of cannabinoids, the biologically active compounds unique to this plant. To the best of our knowledge, most metabolomic works on C. sativa that have been reported previously focused their investigations

The chemical composition of the inflorescences from four Cannabis sativa L. monoecious cultivars (Ferimon, Uso-31, Felina 32 and Fedora 17), recently introduced in the Lazio Region, was monitored over the season from June to September giving indications on their sensorial,

Nature has developed many pathways to produce medicinal products of extraordinary potency and specificity with significantly higher efficiencies than current synthetic methods can achieve. Identification of these mechanisms and their precise locations within plants could substantially increase the

In Europe, authorities frequently ask forensic laboratories to analyze seized cannabis plants to prove that cultivation was illegal (drug type and not fiber type). This is generally done with mature and flowering plants. However, authorities are often confronted with very young specimens. The aim of

The results of an indoor hydroponic Cannabis growth study are presented. It is intended that this work will be of assistance to those with an interest in determining an estimation of yield and value of Cannabis crops. Three cycles of six plants were grown over a period of 1 year in order to

Cannabis is a chemically diverse domesticated plant genus which produces a unique class of biologically active secondary metabolites referred to as cannabinoids. The affinity and selectivity of cannabinoids to targets of the human endocannabinoid system depend on alkyl side chain length, and these

A popular internet site describes cannabis as "a leafy plant, the leaves and flowering tops (buds) of which may be either smoked or eaten. It also comes in a more concentrated resinous form called hashish, and as a sticky black liquid called hash oil". It is said that users often report a pleasant

OBJECTIVE To determine the delta-9-tetrahydrocannabinol (THC) content of cannabis seizures in Egypt. METHODS Unheated and heated extracts of cannabis seizures were prepared from the dried flowering tops and leaves (marijuana) or from the resin (hashish) and subjected to analysis using high

Growth characteristics of Cannabis saliva L. are indispensable factors to verify the statements by the criminals of illegal cannabis cultivation. To investigate growth characteristics of C. sativa, two varieties, cannabidiolic acid (CBDA)-rich (CBDA-type) which being cultivated for fiber production
