摘要

甜高粱（,Sorghum bicolor,(L) Moench）“凯勒”种子经不同剂量（0、10Gy、30Gy、50Gy、80Gy）80MeV/u碳离子注入后，其M2代幼苗对40℃高温胁迫作出了不同的响应：株高、叶绿素含量变化不大，相对低剂量（10Gy、30Gy）碳离子处理使M2代幼苗生物量高于对照CK（0Gy）和高剂量（50Gy、80Gy）处理，同时从丙二醛（Malondialdehyde，MDA）和可溶性糖含量的变化来看，30Gy碳离子辐射处理组MDA和可溶性糖含量降低，提高了M2代幼苗的高温抗性。

Abstract

Sweet sorghum (,Sorghum bicolor, (L) Moench) seeds were implantated by carbon ion for different dose (0Gy, 10Gy, 30Gy, 50Gy, 80Gy) respectively, then plant height, biomass, contents of chlorophyll, malondialdehyde (MDA) and soluble sugar of M2 seedlings were measured in order to investigate the response of M2 seedlings to heat stress. The results show that plant height and chlorophyll content are changed unobviously among all treatments. Biomasses of M2 seedlings are higher after low dose (10Gy, 30Gy) of carbon ion implantation than that of high dose (50Gy, 80Gy) treatment, while the treatment of carbon ion implantation for 30Gy enhances the heat tolerance of M2 seedlings by decreasing the content of MDA and soluble sugar.
