稀土元素镧对中国樱桃试管苗生长的影响

Effect of Rare Earth La on Growth of Cherry Plantlets in Vitro

研究了 L a对中国樱桃试管苗再生与生长的作用。结果表明 ,适宜浓度的 La( 1 0～ 40 mg/L )能够促进樱桃试管苗的生长与分化 ,有利于对培养基中微量元素的吸收。但高浓度 L

The effects of La on regeneration and growth of Chinese cherry were studied. The results showed that the optimum concentration of La (10~10 mg/L) could promote the growth of plantlets and increase differentiation ration, as well as was beneficial to absorption of element. Howerer, La in high level inhibited the growth of cherry plantlets.
