60Co-γ射线辐照澳洲坚果种子后的苗期辐射效应
The Radiation Effects of 60Co-γ Rays Irradiation on Macadamia Seeds at Seedings Stage
摘要
Abstract
To study the radiation effects of 60Co-γ rays irradiation on Macadamia seeds.The seeds of four Macadamia cultivars were irradiated by different doses (0、40、100、200 Gy)of 60Co-γ rays,and then the effects of irradiation on mutation populations were investigated.Results showed that the average extending of diameter per annum of three cultivars (Yunao 57,Yunao 51,Yunao 58) was inhibited with irradiation dose increase.However,there was a little promotion on the average extending of diameter per annum of Yunao 41.Compared with CK populations,the coefficient of variation in mutation populations are larger as well as the maximum value,minimum value and the range,enriched the diversity among plants.Based on the percentage about the number of flowering and the number of fruiting between mutation populations and CK populations,4 mutants with good traits were selected.It provides evidence that the mutation breeding could be used for new variety selection of Macadamia with high-yield and high-quality.关键词
