single plant efficiency的意思|示意

In practical rice breeding pro-grams, multi-trait index selection for plant yield improves selection efficiency by 20.42%, compared to single-trait selection.

在水稻育种中应用选择指数方法进行综合选择比对单株产量单一性状直接选择效率高20.42%，应用前景广泛。

In the condition of nutrient solution culture, the plant speed up horizontal growth but slow down vertical growth, raise the single fruit weight but reduce the efficiency of bearing fruit.

水培条件下能加快植株的横向生长但减慢了纵向生长，提高单果重但降低了座果率。

Therefore, high grain weight and low nitrogen content of single plant are the basic characteristics of high-yielding and high-efficiency hybrids.

所以，较高的粒重和较低的植株氮含量是高产氮高效品种的基本特征。
