摘要
用60Coγ射线辐照扶芳藤枝条,扦插苗平均分枝数与辐照剂量呈极显著负相关。随着辐照剂量的增大,倾斜和匍匐生长的植株比例呈增加趋势。80 Gy处理有利于使植株的叶色在冬季仍保持绿色。V1代筛选出株高、平均节长、粗/长、叶形指数、叶面积以及枝条枯梢、分叉、叶序变化等性状的变异体。
Branches of Euonymus fortunei were irradiated with ^60 Co γ-rays. The average number of new branches per plant was negatively correlated with irradiation dose. With the increase of irradiation dose, the rates of slanting and creeping types of plant increased. 80Gy irradiation was fit for leaves to keep green in winter than other applied doses. Phenotypic variation were observed in V, generation, including variance in height, average node length, diameter/height, leaf shape index, leaf area, blasted tips, biforked tips and phyllotaxis.
