摘要:

【目的】研究不同粒级春小麦品种间、粒级间种子活力的差异。【方法】采用3种不同的种子活力简易指数计算方法,分析新春29号、新春34号、新春11号、新春30号等4个当季收获品种大粒、小粒2个粒级的种子活力。【结果】不同品种间种子活力均达到了极显著性差异,相同品种中的大粒种子与小粒种子间呈极显著性差异,但不同品种间的大粒、小粒种子活力大小排序并不一致。【结论】春小麦不同品种种子活力高低不仅要依据种子活力指数计算方式,还要根据其农艺性状或生理生化特性进行综合判定;同一品种春小麦种子,体积大、千粒重高则表现出较高的活力,不同品种种子体积的大小和千粒重的高低与种子活力高低并无较一致关系,因此不能仅依靠单一的指标判定种子活力的高低。

Abstract:

【Objective】 Study on the differences in seed vitality between different grain sizes of spring wheat varieties and grainsizes.【Methods】 The purpose of the study is to determine the differ by using 3 kinds of calculation methods on varieties and sizes spring wheat. 【Results】 The results showed that when using different calculation methods for the calculation of different varieties of seed vigor, the results were very significantly different; The ranking of seed vigor size was also inconsistent between different varieties; In addition, when the calculation methods were used to calculate the seed vigor, differences were shown between large seeds and small ones in different varieties. Therefore, the comparison of seed vigor of different spring wheat varieties should not be only based on the calculation method of seed vigor index, but also according to the comprehensive agronomic characters and physiological and biochemical characteristics to make the judgment. 【Conclusion】 Spring wheat seeds of the same variety which have large size and high 1000 grain weight show high vigor. There is no obvious relationship between the seed size and 1000 seed weight of different varieties and the seed vigor, so the seed vigor cannot be determined by a single index. The same varieties, large size or high grain spring wheat seeds, its energy is higher, different varieties, the size of the volume and level of high and low and seed vigor and has no obvious relation, so we can't just rely on a single index to determining the seed vigor

Key words: spring wheat; seed sizes; seed vigor
