新疆春小麦黑胚发生与产量及加工品质之间的关系

通过多点分析春小麦加工品质、产量表现和小麦黑胚发生的特点,发现干旱区春小麦黑胚发生率受环境的影响比较大,同一品种在不同地区表现结果不同,同时小麦的籽粒加工品质和产量也受环境条件的影响.小麦抽穗至成熟期间低温、多雨的环境条件有利于小麦黑胚病的发生,也有利于产量的提高,但这种环境条件不利于优良品质的形成.黑胚率高的小麦千粒重和容重较高,降落数值较小,发芽的可能性增大,籽粒蛋白质含量较低,面团流变学特性较差,小麦总体加工品质变差.

The relation between yield quality and black point rate of spring wheat in Xinjiang

Through analyzing the quality,the yield and the black point rate of spring wheat in different site of arid area,we found that the black point rate of spring wheat in arid area is greatly affected by the environmental factors.The black point incidence is dissimilar in different regions for the same cultivar.The yield and quality of wheat are also affected by the environmental factors. The effects of environment factors on the black point rate,yield and quality of spring wheat have certain correlations.The low temperature and damp are in favor of the black point incidence of spring wheat and improve the yield,but this bad environment is not favor of development of good quality.The result indicates that because of different cultivars and environments,the wheat seed with high black point rate has high 1000-kern weight and test weight,low falling number,high probably of sprouting,low protein content,low dough intensity,and bad quality of wheat seed.
