Plant production processes and nitrogen metabolism of chinese cabbage (Brassica chinensis L.) when grown under led illumination
Submitted by Гость (not verified) on Tue, 07/09/2024 - 16:45The paper describes two series of experiments with Chinese cabbage (Brassica chinensis L.). The authors studied the productivity of crops and distribution of dry matter and nitrate pool in plant tissues. Plants were grown in a non-circulating passive hydroponic installation under white and red LEDs in nutrient solutions with various nitrogen concentrations (nitrate -from 40 to 150 mg/l, ammonia -from 0 to 70 mg/l). The study found positive correlation between the accumulation of dry weight of plants and the nitrogen concentration in the nutrient solution in the range from 40 to 120 mg/l.
