| 摘 要： | 对小麦新品种百农矮抗58籽粒灌浆过程中干物质积累分配和籽粒灌浆特点进行了观察研究。结果表明:百农矮抗58籽粒灌浆过程中干物质积累的中心,在籽粒形成期为茎叶鞘和颖壳穗轴,随后逐渐由茎叶鞘、颖壳穗轴向籽粒转移;籽粒增重总的趋势表现出“慢—快—慢”的特点;籽粒灌浆中期和籽粒灌浆末期有2个灌浆高峰;百农矮抗58籽粒灌浆渐增期短,快增期长,缓增期较长,有利于提高千粒重。

| Abstract: | Accumulation and distribution of dry matter and grain filling of new wheat variety Bainong AK58 were observed.The results showed that the dry matter accumulation centers of Bainong AK58 were stems,leave,sheath,glumes and ear axis during the stage of grain forming,then transferred to grains gradually;the tendency of grain weight increasing was "slow-quick-slow" with two filling peaks in the middle and last phases of grain filling.The quickly increasing stage of grain weight of Bainong AK58 was longer than the slightly increasing stage which was longer than the slowly increasing stage,which was advantageous to increase the grain weight. |
