Abstract:

Triazine compounds -- simazine and atrazine in doses of up to two kilograms per hactare dont have any effect on physiological processes in hemp plants, however, doses of two kilograms per hectare and over have unfavorable effects of these processes. Under the influence of toxic action by atrazine and simazine there occurs weakening in the process of respiration and synthesis of organic compounds in the hemp leaves is suppressed the carbohydrate-protein exchange is disrupted and there is a noticeable lowering in the uptake of mineral nutrient elements -- nitrogen, phosphorous, and potassium -- in the hemp plants. The physiological disruptions lead to a lowering of the productivity of the plants and a lowering in the yield of hemp stems, seeds, and fibres.
