Abstracts |
The effects of Glomus mosseae (GM) on growth and physiological characters of Atractylodes macrocephala Koidz. under different P-applied levels in the pot culture were studied. The results showed that GM and Atractylodes macrocephala had symbiosed efficiently. Inoculating GM significantly increased mycorrhizal infection rate at 0-0.4 g P/kg soil level. The infection rate reached the highest level at 0.05 g P/kg soil, but the infection rate reduced with the increase of phosphorus levels. Effect of inoculating was obvious to underground part. At 0.1 g P/kg soil level, the root was the longest, the adult plant was the highest and the dry weight of underground part was the most. It was found that GM could increase the content of soluble sugar and soluble protein, improve activity of protective enzymes under suitable phosphorus level. In a word, inoculation effect of GM was the best under 0.05-0.1 g P/kg soil. |
