亚精胺引发对水分胁迫下水稻种子活力及幼苗生理特性的影响
Effects of Spd Priming on Seed Vigor and Seedling Physiological Characteristics of Rice under Water Stress
摘要
Abstract
To study the effects of Spd priming on rice(Oryza sative L. Subsp. Indica) seed vigor and seedling physiological characteristics under water stress, seeds of rice Han116 and Xiangzaoxian32 were primeded for 36 hour with 0. 25 mmol · L-1 of Spd and water. Nonprimed and primed seeds were germinated under different water stress. The seed vigor and seedling physiological characteristics were investigated and compared. The results showed that Spd and water priming treatments significantly improved seed vigor and seeding growth, raised the activities of POD,CAT and SOD, increased Pro and Spd contents and decreased MDA contents. The results suggested that Spd and water played a vital role in promoting rice seed vigor and seedling physiological characteristics. The study also indicated that the effects of Spd priming were better than that of water and Spd was better priming effect on Han 116 than Xiangzaoxian32.关键词
