作物生育期是一个重要性状,它不仅决定产量水平,而且也经常决定在一定的局部地区种植某一品种类型的可能性。生育期这一性状可用不同的指标表示,如播种至抽雄或吐丝期的日数,以及收获时籽粒含水量等。本研究中利用收获时果穗(不含苞叶)干物质的含量(％)作为生育期指标。
The crop growth period is an important trait that determines not only the level of yield but also the likelihood that a particular type of plant will be planted in a given area. The traits of fertility are indicated by different indicators such as the number of days from sowing to tasseling or silking and the grain moisture at harvest. In this study, the amount of dry matter (%) at the ear of harvest (without husk) was used as the indicator of growth period.
