不同肥水条件下玉米自交系产量构成要素分析

Study of Water and Nitrogen Condition on Yield Components of Maize Inbreds

选用8个玉米自交系,采用盆栽实验,在2个肥力水平下,进行了玉米自交系的适应性研究。结果表明,在低肥力水平下,不同玉米自交系不仅产量存在较大的差异,而且对肥力的响应度和敏感度也不相同,并通过根冠变化和籽粒产量将8个自交系进行分类探讨,为育种工作提供一定的理论依据。

Under 2 fertility levels, 8 maize inbreds, a pot experiment is used to the adaptability of studying. The result show that the yield of different maize inbreds are more different, but also responsiveness and sensibility of fertility are different under low fertility level. According to root cap change and seeds production, the classification study of 8 maize inbreds provide a theoretical basis for breeding.
