亩穗数是小麦产量的决定因素之一,而穗数又是由主穗及分蘖穗数两部分构成,因此,分蘖穗对小麦产量就具有举足轻重的影响。1982、1983两个年度我们对小麦品种郑选进行了单株分蘖追踪记载,记清各分蘖出生成穗情况,成熟后取回室内,分主穗和分蘖穗考察其经济性状,然后分不同类型统计并分析其间的关系。
The number of ears per acre is one of the determinants of wheat yield, while the number of ears is composed of two parts: the main spike and tillering spikes. Therefore, tillering spike has a decisive influence on the yield of wheat. In 1982 and 1983, we conducted a single tiller tracing record of wheat variety Zheng Xuan. We recorded the spawning status of each tiller, and retrieved the indoor, main and spike panicles after maturity to investigate their economic traits, and then divided them into different types Statistics and analysis of the relationship between.
