Newest firstHemp (Cannabis sativa L.) is one of the oldest cultivated plants in the world. It is a wind-pollinated and heterozygous species, and diverse phenotypes can occur within population varieties. In our study, three different hemp varieties-('Carmagnola Selected' (CS), 'Tiborszallasi' (TS) and 'Finola selection' (FS))-were grown. Based on visual characteristics, two, five and four phenotypes were identified within CS,…
Open article record in new tab ↗Cannabis sativa L. is a predominantly dioecious species, but sex expression is highly plastic and can be modified by genetic, hormonal, developmental, and environmental factors. This plasticity has major implications for commercial production because hermaphroditic expression in female plants can cause unintended pollination, seed formation, reduced floral quality, and losses in cannabinoid yield. This review summ…
Open article record in new tab ↗Cannabis sativa, a species within the Cannabaceae family, produces a diverse range of phytochemicals, notably cannabinoids and terpenoids, with significant physiological and pharmacological relevance. Among its phytochemicals, Δ9-tetrahydrocannabinol (THC) and cannabidiol (CBD) are the most studied for their psychoactive and medicinal properties. However, emerging evidence indicates that chronic or excessive expos…

Open article record in new tab ↗Light spectral composition plays a central role in regulating plant growth, morphology, nutrient uptake, and pigment biosynthesis, particularly in controlled-environment agriculture. This study investigated the effects of targeted LED spectral modulation, focusing on green light deprivation and different red-to-blue (R:B) ratios at constant photon flux density, on morphological traits, mineral composition, and pho…
Cannabis sativa is a multipurpose dioecious species whose crop performance is governed by sex expression. Although sex is genetically determined by an X/Y chromosome system, plants can develop flowers of the opposite sex through sex reversion, commonly induced by manipulating endogenous hormone levels using plant growth regulators (PGRs). Here, we evaluated the effectiveness of PGRs that promote or inhibit major h…
Open article record in new tab ↗Colletotrichum kahawae is the causal agent of coffee berry disease (CBD), a disease restricted to African countries producing C. arabica, which affects coffee production and is a potential phytosanitary threat for coffee plants growing at other latitudes. The inheritance of resistance to C. kahawae conferred by the R gene (Ck-2/Ck-3) in the Rume Sudan variety of coffee was previously reported as simple Mendelian (…
Oleoresins are complex natural lipophilic matrices traditionally analyzed using chromatographic techniques that require extensive sample preparation, derivatization, and authentic standards. Amazonian oleoresins from Copaifera and Eperua species (Fabaceae) represent valuable bioresources with recognized pharmacological potential, largely attributed to diterpenoids such as copalic and hardwickiic acids, as well as…
The induction of staminate flowers in genetically female Cannabis sativa is widely used for feminized seed production, yet its anatomical and ontogenetic basis remains poorly understood. This study examined silver thiosulfate (STS)-induced masculinization in genetically female plants of C. sativa cv. 'Pasionaria S' using stereomicroscopy, light microscopy, confocal laser scanning microscopy, pollen viability assay…
Open article record in new tab ↗Cannabis sativa (C. sativa) is widely recognized for its therapeutic potential, historically attributed to its cannabinoid content. Some of the phytocannabinoid compounds of C. sativa are mediated through interactions with the endocannabinoid system, while some are able to modulate the interaction between cannabinoids and the endocannabinoid system. Additionally, the non-cannabinoid group exhibits a broad range of…
Open article record in new tab ↗Cannabis sativa L. is an economically significant multi-use crop valued for fiber, seed, and phytochemical production. Compared with other crops, advancement in Cannabis sativa has been slow due to regulatory constraints and genetic resource limitations. Recent advances in technology have transformed the research landscape, supporting a deeper understanding of the genetic architecture underlying key agronomic trai…
In vitro hedging; combined with the fed-batch liquid media process is an innovative system that generates multiple sterile plants without the use of exogenous cytokinin. This combined process was demonstrated with Cannabis sativa ('Cherry1', 'BaOx', 'T1', 'Peach') grown in vessels of three different physical states-stationary agar (A); stationary Oasis® infused with liquid (OILs); and agitated Oasis® infused with…
Open article record in new tab ↗Cannabis sativa produces pharmacologically valuable cannabinoids. In this study, we developed and optimized a transient transformation system using Cannabis sativa 'Cheungsam' to facilitate gene functional analysis. Various experimental conditions, including plant developmental stages, light conditions, Agrobacterium strains, tissue types, and physical treatments such as sonication and vacuum infiltration, were sy…
Open article record in new tab ↗Postharvest operations affect the yield and quality of industrial hemp (Cannabis sativa L.). This study aimed to investigate the postharvest drying and curing effects on the key quality and safety indicators of cannabinoid-type hemp. Freshly harvested hemp inflorescence of Hempress and Wild Bourbon cultivars were dried by three methods: (1) Hot air drying at 75 °C; (2) Ambient air drying at 25 °C; and (3) Freeze d…
Open article record in new tab ↗The roles of endophytes in Cannabis sativa (cannabis, hemp) remain poorly explored. While in vitro studies suggest that there can be several benefits, such as plant growth promotion and protection against pathogens, more in planta studies are needed. This review summarizes the bacterial and fungal endophytes previously reported in tissues of C. sativa and discusses the factors influencing their presence, as well a…
Open article record in new tab ↗Drought is a major constraint on Cannabis sativa productivity and cannabinoid yield, yet the physiological mechanisms underlying genotypic variation in drought responses remain poorly understood. We hypothesized that (i) more vigorous genotypes would sustain higher photosynthetic rates, (ii) drought would constrain photosynthesis through both diffusional and non-diffusional limitations, and (iii) water deficits wo…
Water availability is a key factor affecting both morphological development and secondary metabolite production in Cannabis sativa L. This study evaluated the effects of water stress applied during the vegetative and flowering stages on plant performance, cannabinoid concentration, and terpene composition in two Chemotype III (cannabidiol-dominant) varieties. Plants were subjected to moderate and severe water stre…
Open article record in new tab ↗The plant callus culture technique is an emerging source of bioactive compounds with potential applications in cosmetics and pharmaceuticals. Callus-derived extracts contain high concentrations of secondary metabolites with significant antioxidant and anti-inflammatory properties when elicited. Cannabis sativa L. has been used for its medicinal effects; however, the potential of its C. sativa callus extract (CCE)…
Open article record in new tab ↗Knowledge of the genetic diversity and resistance genes of Coffea canephora genotypes is essential to identify genetic resources that are better adapted to current climate conditions. This study aimed to molecularly characterize and evaluate the genetic diversity of coffee plants cultivated in Rondônia (Amazonia), Brazil, using SNP molecular markers, and to identify plants carrying resistance genes to two major co…
