不同小麦品种籽粒灌浆特性及产量品质研究
Study on Grain Filling Characteristics,Yield and Quality of Different Wheat Varieties
摘要
Abstract
This study used six new wheat varieties as materials to explore the yield components and grain filling patterns of different varieties,and fitted the grain filling process.The results indicated that there were certain limitations to the contribution of the number of spikes per unit area(hectare)to yield,and the number of grains per spike and thousand grain weight were significantly positively correlated with yield.The maximum grouting rate Gmax and average grouting rate Gmean were significantly positively correlated with thousand grain weight;the rapid in-crease period grouting rate G2,slow increase period grouting rate G3,and average grouting rate Gmean are all significantly positively correlated with the maximum grouting rate Gmax and the thousand grain weight.The accumulation of grain dry weight(W1,W2,W3)in the three stages of gradual increase,rapid increase,and gradual increase was significantly positively correlated with thousand grain weight.There was no sig-nificant correlation between the grouting time parameters T,T1,T2,T3 and thousand grain weight.The rapid increase grouting rate G2,the slow increase grouting rate G3,and the duration of the rapid increase period T2 and the slow increase period T3 were all significantly negatively correlated.In production,varieties with fast grain filling rates and corresponding cultivation techniques could be selected to improve the grain filling rate during the rapid growth period,achieving the goals of increasing thousand grain weight and yield.Considering the characteristics of varieties such as fast grouting rate,maximum grouting rate occurrence period,yield,and quality,it was recommended to prioritize planting Yangmai 33,Zhenmai 12,and Ningmai 13 in Xinghua City.关键词
