本文报导了播种期的小麦、大麦和小黑麦5个品种花后源库性状的影响。使用了逻辑斯蒂方程和二次多项式模型等统计方法,从开花到成熟定期测定籽粒和营养器官干重、叶面积的发展及持续期等性状及其与气候因子的关系。结果表明,播期和品种对多数性状有显著的影响。各性状对插期的敏感性随品种不同而异。提出了品种间粒重差异与灌浆持续期和速度的关系可能依材料、生态环境以及灌浆持续期的划分标准不同而各有主次,在不同条件下,两者相互调节,以保证最大可能地充实籽粒。 This paper reports the effects of the source sinks of five varieties of wheat, barley and triticale during sowing time. The statistical methods such as Logistic equation and quadratic polynomial model were used to determine the dry weight of vegetative organs and vegetative organs, the development and duration of leaf area, and their relationship with climatic factors from flowering to maturity. The results showed that sowing dates and varieties had significant effects on most traits. The sensitivity of each trait to the insertion period varies with the variety. It is suggested that the relationship between grain weight difference and duration and speed of grain filling may differ according to materials, ecological environment and grouting duration, and each has its own order. Under different conditions, the two are mutually adjusted to ensure the maximum possible Enrich grain.
