| 摘 要： | 为了解河西地区不同熟期类型小麦品种籽粒灌浆特性及其对粒质量的影响,对6个不同熟期类型(早、中、晚)春小麦品种的籽粒灌浆特性进行了比较研究.用logistic方程拟合籽粒灌浆过程,并推导出了次级参数,同时对粒质量与不同参数进行了相关和回归分析.结果表明:晚熟品种平均灌浆速率(R)高、灌浆期(T)较长、灌浆高峰灌浆强度大且持续时间长,缓增期灌浆速率(R3)急剧下降.早熟品种灌浆期短,灌浆高峰灌浆强度小、持续时间短,缓增期灌浆速率高于中、晚熟品种.回归分析结果表明:从整个灌浆过程来看,平均灌浆速率对粒质量的影响大于整个灌浆持续时间.从阶段灌浆参数分析来看,渐增期灌浆速率(R1)、快增期灌浆速率(R2)和缓增期灌浆持续时间(T3)是影响河西地区不同熟期春小麦粒质量的主要参数,其中快增期灌浆速率对粒质量的作用更大一些.

| Abstract: | To understand the grain-filling characteristics of different maturity varieties and the relationship between the traits and mature period,a comparative study has been made on the grain-filling characteristics of 6 different maturity type wheat.The process of grain filling was simulated by Logistic curve regression equation,and got a series of second parameters.The relationship between kernel weight and their parameters was analyzed by correlation analysis and multiple linear regression analysis.The results ... |
