不同纬度生态环境对新疆不同类型冬小麦品种淀粉糊化特性的影响
Effects of Different Latitude of the Ecological Environment on Paste Property of Different Types Winter Wheat Cultivars in Xinjiang
摘要
Abstract
[Objective]The project researched the different latitude and climatic factors affecting the paste property of Xinjiang different quality cultivars of winter wheat. [ Method ] In 2009 and 2010, seven representative winter wheat cultivars were planted in seven locations with the latitude varying from ( N 36 -46°) in Xinjiang. After maturity and harvest, RVA was used to determine the paste property parameters of each winter wheat cultivars in every location. [Result]The results showed that the difference of winter wheat paste properties among locations, cultivars, years and the interaction between them were significantly obvious. The quality characteristic mean value in Tacheng wheat was the best while the quality characteristic mean value in Yutian was the minimum. On the other hand, with the latitude increasing, the quality index was also increasing except peak time. Researching the different gluten cultivars, we know that the middle strong gluten wheat means were the highest, next was the middle weak gluten wheat and the strong gluten wheat. According to the correlation coefficients between climatic factors and paste traits of winter wheat, we can know that the latitude, mean temperature were all positive to paste parameters. The sunshine was extremely minus significant to breakdown and positively significant to peak time. The precipitation was minus to all parameters except breakdown. [Conclusion] The paste property of Xinjiang different cultivars of winter wheat are significantly different among locations, cultivars and years. With the latitude increasing, the quality index is also increasing. Too much precipitation is not favorable to improving paste property, but the relatively mean high temperature is beneficial.关键词
