碳离子辐照对甜高粱种子萌发及幼苗酶活的影响
Effect of ~(12)C~(+6) Ions Beam Irradiation to Sorghum bicolor L. on Seed Germination and Enzymes Activity in Seedlings
摘要
Abstract
[Objective] The aim was to study the effect of ~(12)C~(+6) ions beam irradiation to two varieties of Sorghum bicolor L. on seed germination and some enzymes activity in seedlings with different doses, and provided a theoretical foundation for breeding Sorghum bicolor. [Method] After germination, germination potential, germination fraction and enzyme activity were detected respectively. [Result] The results showed that with the dose increased, the germination potential of Sorghum bicolor increaseed first and then decreases, while their germination fraction presented "shoulder like shape"; the activity of LDH, SOD, CAT and GSH-Px increased first and then decreases with doses, they presented slight differences among different enzymes. [Conclusion] Low dose radiation could accelerate germination of sweet sorghum seeds and enzyme activity could remain at a relatively high level. Enzyme activity decreased with high doses and the growth of Sorghum bicolor was inhibited.关键词
