超强筋小麦新品种新麦26籽粒灌浆特性研究
Grain Filling Characteristics of New Strong Gluten Wheat Cultivar Xinmai 26
摘要
Abstract
In order to offer evidence for spread and application of the new strong gluten wheat cultivar Xinmai 26,the grain filling characteristics of Xinmai 26 was studied under field conditions in 2009 - 2010. The results showed that the increase of grain dry-weight showed "S" curve at grain filling period. The entire grain filling period of Xinmai 26 was shorter than that of Xinmai 18 by 3 d. Both the average and maximum of filling rate of Xinmai 26 were higher than Xinmai 18 by 2. 2% and 4. 6%. The gradual increase stage and the rapid increase stage of Xinmai 26 manifested higher filling rate and bigger accumulation. Moreover,the smooth phage of water content during filling of Xinmai 26 was shorter, and water lost quickly after the filling period. In conclusion,Xinmai 26 was characterized by short filling period,high filling rate,high grain weight and good senesced-yellowing. To promote Xinmai 26,the attention should be paid to improve the ears per unit area and grain number, and timely harvest to prevent back flow of grain dry matter.关键词
