Fig. 3From: 24-Epibrassinolide promotes NO3− and NH4+ ion flux rate and NRT1 gene expression in cucumber under suboptimal root zone temperatureEffect of EBR on A; nitrate reductase (NR), B; glutamine synthetase (GS), C; glutamate synthase (GOGAT), and D; nitrite reductase (NiR) activities in leaves of cucumber seedlings under suboptimal RTZ. Treatments with the same lowercase letter are not significantly different by the least significant difference (LSD) test at P = 0.05Back to article page
