超干处理与贮藏条件对一串红种子生活力与生理变化的影响

本试验采用硅胶干燥法对一串红种子进行超干处理，将含水量为8.9％的一串红种子含水量分别降低至4.5%、3.4%、3.0%、2.7%和2.2%；同时研究了不同贮藏条件对不同超干种子生活力与生理变化的影响。种子发芽率、活力指数、电导率和脱氢酶活性等试验结果表明：超干处理后含水量为3.4 ~ 4.5%的一串红种子，经过13个月的贮藏（低温和室温）后，其生理指标保持在较好的水平，种子活力较高。

Effects of Ultradrying Treatment and Storage Temperature on Vigor and Physiological Changes of Salvia splendens Seeds

Salvia splendens seeds were taken as the experimental material, the moisture of the seeds was reduced from 8.9％ to 4.5%、3.4%、3.0%、2.7% and2.2% respectively by silicon gel in a closed condition. The seeds were stored at different temperature after ultra dry, some physiological changes were investigated as well, such as the germination rate, vitality index, electric conductivity and the activity of dehydralase. The results suggested that the seeds with 3.4 ~ 4.5% moisture content had a good vitality and germination rate after storage.
