【摘要】 用60 Coγ射线与稀土复合处理甜菜种子 ,对甜菜块根含糖量和产量的影响进行了研究。结果表明 ,用60 Coγ射线 5 0Gy剂量辐照甜菜种子后再用稀土元素 75 0g hm2 进行浸种处理 ,能促进甜菜的根系生长 ,使甜菜块根的含糖量比对照提高了 1 1 9% ;产量与对照相比增产了1 3 5 % ,差异达显著水平更多还原

【Abstract】 The effect on sugar content and yield of beet was studied by using 60Co γ-ray and rare earth elements(REE) to treat seeds of beet.The results indicated that 60Co γ-ray of 50Gy and seed-soaking in 750g/hm 2 of farm REE could improve the root growth of beet,raise the sugar content of beetroot by 11.9% and yield by 13.5% compared to that of CK.The differences reached the significant level.更多还原
