Studies were carried out on influences of replacement of 25% NO~-_3-N with NH~+_4-N in nutrient solution(enhanced ammonium nutrition) on tomato growth and activity of such key enzymes in N assimilation and organic acids as nitrate reductase(NR),glutamine synthetase(GS)and phosphoenolpyruvate carboxylase(PEPcase)in tomato leaves and fruits sampled at different developmental stages.
采用砂培实验研究NH4+-N部分代替NO3--N对番茄的影响,结果表明:与全硝处理(100%NO3-)相比较,增铵处理(NH4+∶NO3-=25%∶75%)下番茄鲜果重显著提高;同时叶片内NO3--N含量随增铵而显著降低,叶片与果实内NH4+-N含量及果实的可溶性蛋白含量随增铵而升高;增铵条件抑制了叶片和果实的硝酸还原酶(NR)活性,提高了叶片和果实的磷酸烯醇式丙酮酸羧化酶(PEPcase)活性及叶片谷氨酰胺合成酶(GS)活性,但对果实的谷氨酰胺合成酶(GS)活性影响不大。
