TLDR
In this paper, the effects of heavy metal salts (Pb(NO3)2, CuSO4, and ZnSO4) on phytohormonal status and sex expression in various cultivars of marijuana (Cannabis sativa L.), a dioecious plant, grown on Knop nutrient medium.Abstract:
We studied the effects of heavy metal salts (Pb(NO3)2, CuSO4, and ZnSO4) on phytohormonal status and sex expression in various cultivars of marijuana (Cannabis sativa L.), a dioecious plant, grown on Knop nutrient medium. Pb(NO3)2 and ZnSO4 were added to the medium at the concentration of 10−9 M, and CuSO4, at the concentration of 10−10 M. Plant were grown under controlled conditions at luminescent illumination, 22–24°C, and 80% humidity. The contents of GA and zeatin were determined by HPLC. Copper and zinc salts induced plant feminization, and this effect was coupled with zeatin accumulation. Lead salts favored plant masculinization coupled with GA accumulation. Thus, a shift in sex expression in marijuana plants was correlated with the heavy metal action on the balance of phytohormones, GA and zeatin.read more

Review on different mechanisms of sex determination and sex-linked molecular markers in dioecious crops: a current update
TL;DR: The present review emphasizes the mode of sex determination among dioecious plants vis-a-vis summarizes the works related to gender specific markers generated using male and female plants from agriculturally important dioemious crops.

Protective role of selenium on cucumber (Cucumis sativus L.) exposed to cadmium and lead stress during reproductive stage role of selenium on heavy metals stress
TL;DR: In this paper, the authors investigated the effect of selenium on flowering indices, sex determination of flowers, and yield of cucumber plant under heavy metal stress conditions, and found that the effect was negligible.

TL;DR: The results suggest that pectin, agronomic traits, and fiber traits are unsuitable targets in breeding programs of hemp, as their large G×E interactions might lead to unexpected phenotypes in untested locations.
Changes of photosynthesis-related parameters and productivity of Cannabis sativa under different nitrogen supply
TL;DR: In this article, the authors evaluated the impact of different doses of nitrogen fertilizer on physiological processes of hemp plants and evaluated its effect on several yield parameters, including seed and fiber yield and quality.

Tests of a mechanistic model of one hormone regulating both sexes in Cucumis sativus (Cucurbitaceae)
Tongjia Yin,James A. Quinn +1 more
TL;DR: Results indicated that there is only one hormone, not two, regulating sex expression in cucumber, and that the sex hormone is likely to be ethylene, and all assumptions and predictions of the one-hormone model were confirmed.

Regulation of sex determination in maize
TL;DR: Genetic analysis has shown that stamen abortion and pistil abortion are under the control of two different genetic pathways.

Hormonal regulation of sex expression in plants.
TL;DR: It is interesting that both plant hormones, gibberellins and ethylene, cause the arrest of stamen primordial in maize and cucumber, respectively, which indicates that ethylene‐ and gibberenllins‐signaling pathways mediate the arrest (by PCD) of stamens primordia in maizeand cucumber.
