Silicon Reduces Zinc Absorption and Trigger Oxidative Tolerance Processes Without Impacting Growth in Young Plants of Hemp (Cannabis Sativa L.)

“…Silicon however did not signi cantly improve growth of hemp exposed to Zn excess. In order to combine phytostabilization with non-food production, the properties of the harvested biomass have to remain compatible with the requirements of industry from a qualitative point of view (Luyckx et al, 2019). It would be therefore appropriate to link morphophysiological observations with the distribution of HM in hemp tissues.…”

“…Besides, oversynthesis of glutathione requires large quantities of S. Hemp increased the S accumulation in roots, stems and leaves in the presence of Zn excess con rming that hemp is able to trigger this protective mechanism. However, it is important to keep in mind that to combine phytostabilization with non-food production, the properties of the harvested biomass have to remain compatible with the requirements of industry from a qualitative point of view(Luyckx et al, 2019). Additional work is therefore needed to precise the impact of Zn excess on valuable plant parts.Although Si is not considered as essential for plants, it intervenes as a bene cial element in their defence and growth.…”

Impact of Nitrogen Nutrition on Cannabis sativa: An Update on the Current Knowledge and Future Prospects

“…Hemp shows a number of interesting agricultural features, such as low nitrogen (N) input requirement [2,13,14,15], heat tolerance [2,15], phytoremediation [16,17], positive effects on environments [18], benefits in crop rotation [19] and availability of high-yield varieties [20,21].…”
