摘要
[目的]研究不同小麦品种主茎和分蘖的干物质积累状况以及产量和产量构成的差异.[方法]采用随机区组试验设计,对8个不同小麦品种主茎和分蘖的干物质积累及产量构成因素进行分析.[结果]皖麦36和洛麦23主茎和分蘖的干物质积累量总体较多.洛麦23主茎和分蘖的单穗重均较高,其产量最高;泰农18主茎和分蘖的单穗重均较低,其产量最低.供试8个小麦品种中,洛麦23的产量最高,淮麦35、良星99、邯6712和矮抗58的产量也相对较高,泰农18的产量最低.[结论]在高密度下洛麦23较适合大面积应用,淮麦35、良星99、邯6712和矮抗58 4个小麦品种也可以在生产中应用.
Abstract
[Objective] To study difference on the dry matter accumulation and yield components of wheat main stem and tillers stem.[Method] Taking eight wheat varieties as research object,the effect of the dry matter accumulation and yield components of wheat main stems and tillers stems were analyzed by using randomized block design.[Result] Wanmai 36 and Luomai 23 had more dry matter accumulation.The main stem and tillering panicle weight of Luomai 23 was the highest,so the yield was the highest.Main stem and tillering panicle weight of Tainong 18 were the low,the yield were low.From the view of yield in the eight wheat varieties,Luomai 23 was the highest,then followed by Huaimai 35,Liangxing 99,Han 6712 and Aikang 58,Tainong 18 was the lowest.[Conclusion] Luomai 23 is the best wheat cultivar to use in production,Huaimai 35,Liangxing 99,Han 6712 and Aikang 58 are also good wheat cultivars to use in production under high density.
