Effects of Seed Size on Yield and Quality of Peanuts
-
摘要: 在恒温箱和田间条件下,研究2个花生品种不同种子大小对发芽、产量以及品质的影响。结果表明,大粒种子具有较高的活力指数和出苗率,但其发芽率和发芽指数略低于小粒种子和中粒种子。荚果产量以大粒种子最高,其次为中粒种子,最低的为小粒种子。大粒种子较高的荚果产量是与其花量较多,前期有效花率高,根系活力较强以及较多的干物质积累等特性密切相关,这些特性为大粒种子较多的荚果数和高的生产力的形成奠定了良好的基础。花生蛋白质和脂肪含量主要受品种遗传特性和环境条件的作用而表现一定的差异,种子大小对两者影响较小。Abstract: Effects of different seed sizes on germination, yield and quality of peanuts were investigated in this study under the condition of incubator and field. The results showed that the vigor index and emergence rate of the large seed were higher than those of the small seed, but germination rate and germination index of the large seed were slightly lower than those of the small and middle seed. The highest pod yield was produced by large seed, followed by middle seed, the lowest pod yield was produced by small seed. There are close relationship between the higher pod yield of big seed and the more blooming, strong root activity in a relatively short period, much dry matter accumulation, and so on, which laid a good foundation for larger pod number and higher productivity. The protein content and oil content of peanut were affected by the genetic characteristics and environmental condition of varieties, the seed size had little effect on both of them.
