微量元素对红豆杉菌根菌生长的影响

Effect of minute elements on the growth of mycorrhizal fungi in Taxus chinensis

微量元素对植物的生长发育有着十分重要的意义。对太行山野生红豆杉(Taxus chinensis var.mairei)菌根菌菌丝在分别加有硫酸锌、钼酸铵以及硫酸亚铁的PDA培养基中的生长发育状况进行了试验研究。所得数据同PDA对照组进行比较分析后,结果表明:Mo元素对红豆杉菌根菌菌丝的生长发育有很好的促进作用;Fe元素明显地促进红豆杉菌根菌菌丝的生长发育;Zn元素在一定范围内对红豆杉菌根菌菌丝的生长发育有一定的抑制作用。实验结果揭示出红豆杉菌根菌生长发育的一些营养因素。

Through the experiment that mycorrhizal fungi from Taxus chinensis var. mairei was cultured in PDA medium added with zinc sulfate or ammonium molybdate or ferrous sulfate, we found that the ammonium molybdate and ferrous sulfate play a promoting role in the process of growth and development of mycorrhizal fungi, zinc sulfate obviously inhibits the growth and development of mycorrhizal fungi.
