Research of Seed Germination Ability and Physiological Change of Peanut Under Different Storage Method
摘要
Abstract
In order to understand the rules of peanut seed germination under different storage conditions, evaluate different storage conditions and provide theoretical basis for peanut seed storage condition and physiological and biochemical mechanisms of seed germination, this paper took big fruit (Yuhua 9326) and small fruit (Yuanza 9102) as materials and storaged them by 3 methods: vacuum, low-temperature and indoor-temperature for 1 year. Seeds harvested the same year served as the contrast and the initial water content, weight and volume of the tested seedswere measured. The vigour of seeds were treated by different ways and physiological and biochemical changes during seed germination were studied. The results indicated that different storage conditions could affect seed germination ability and physilogical property. Compared with the same year seed, different storage methods had affected seed water absorption capacity and reduced seed germination ability by different degrees. The germination potential of seeds harvested in the same year was 23. 12％ ～ 25％, germination rate was 98. 37％ ～ 100％, and germination index was 13.93 ～ 14.28, showing very strong germination capacity. The germination index of seeds storaged under vacuumed condition for one year was 6.07 ～ 6.78. Germination index of seeds storaged under low-temperature condition was 12.14 ～ 13. 57. Germination index of seeds storaged under indoor temperature was around 1.78. Compared with seeds harvested in the same year, the relative electrolytic leakage of seed leaching agent of under indoor-temperature storage, low-temperature storage and vacuumstorage were increased by 99.18％, 31.50％ and 54.78％, respectively.And MDA contents increased by 36.22％, 81.94％ and 169.02％, respectively. After storaged by different ways, the contents of soluble sugar and soluble protein of these 2 varieties decreased to different degrees. The descend range was the largest under indoor-temperature storage, degreasing by 57.35％ and 30.47％ in comparison with seeds harvested in the same year. The contents of soluble sugar and soluble protein had fallen 28. 67％ and 16. 94％ under lowtemperature storage, but the descend range was relatively smaller. Comparison between different peanut varieties showed that storage-tolerance capacity of small fruit is better than that of big fruit. Different storage ways had influenced the peanut seeds physiological activity and germination capacity by different degrees. Comparison among these 3 ways showed that low-temperature storage had less influence over seed vigour and physiological indexes, demonstrating favorable storage result.关键词
