genotypic differences

基本解释

营养液培养条件下对86个棉花基因型苗期进行钾效率筛选，并对其中的28个进行了系统的研究。
Under different soil conditions, there were significant genotypic differences in effects of applying nitrogen fertilizer on nitrogen use efficiency, yield and characters of nitrogen uptake.
在不同土壤条件下，水稻施用氮肥的增产效应、氮肥利用效率和对氮素的积累与分配均存在显著的基因型差异。
Genotypic differences of phosphorus(P) efficiency among 194 Brassica napus L. cultivars were investigated under pot culture in acid soil with a method of two step screening typical cultivars.
