60Co-γ辐照对两个越南油茶品种幼苗的生理影响
Effects of 60Co-γ Irradiation on Physiological Indicators of Camellia drupifera
摘要
Abstract
In order to study the physiologic changes of Camellia drupifera seedlings after 60Co-γ irradiation,the authors did a 60Co-γ by 0 Gy,40 Gy,50 Gy,60 Gy and 70 Gy irradiation of seeds from two excellent materials C.drupifera'Fanlong 3'and'Fanlong 5'and measured chlorophyll content,soluble sugar content,soluble protein content,peroxidase(POD),superoxide dismutase(SOD)in leaves.The result showed that the influence on physiologic index of C.drupifera of 60Co-γ irradiation by various kinds dose was different.The chlorophyll content of 50 Gy group of'Fanlong 3'and'Fanlong 5'were significantly lower than those of other groups(P<0.05).The change tends of soluble sugar content on'Fanlong 3'and'Fanlong 5'were different which showed that the 60 Gy of'Fanlong 3'was relatively low and the 70 Gy of'Fanlong 5'was relatively low.The change tends of soluble protein content on'Fanlong 3'and'Fanlong 5'were the same which showed that the soluble protein contents of 60 Gy treatment were relatively low.The change tends of antioxidant enzyme activity on'Fanlong 3'and'Fanlong 5'were different.The SOD activity of high dose group(60 Gy,70 Gy)was relatively low and the POD activity of 40 Gy treatment was relatively high in'Fanlong 3'.The SOD activity of control group was relatively low and that of 70 Gy treatment was relatively high in'Fanlong 5'.The POD activity of 60 Gy treatment was relatively low and that of 50 Gy treatment was relatively high in'Fanlong 5'.关键词
