在盆栽条件下用丛枝菌根真菌(Arbuscular mycorrhiza fungi)接种黄檗一年生实生苗,研究丛枝菌根对黄檗(Phellodendron amurense Rupr.)生长代谢的影响。结果表明,丛枝菌根显著提高了黄檗的生长及吸收能力,苗木株高、地径及主根长等都显著大于对照植株,增强了苗木根系活力,提高了叶片吸收NPK的能力;接种G.mosseae和G.diaphanum的苗木平均高比对照苗木增加了近20 cm;根系活力与对照相比提高了2.5~2.7倍。丛枝菌根促进了黄檗的生长发育,提高了叶片光合效率,促进根系对矿质营养的吸收,叶片N、P、K含量均有提高,其中接种G.diaphanum的苗木光合效率提高最为突出,光合速率为12.23μmol·m-2·s-1。研究结果可以为黄檗的菌根化育苗和资源保护提供技术依据。
The arbuscular mycorrhizal fungi (Arbuscular mycorrhiza fungi) were used to inoculate the annual seedlings of Phellodendron amurense Rupr. The effects of arbuscular mycorrhiza on the growth and metabolism of Phellodendron amurense Rupr. Were studied. The results showed that arbuscular mycorrhizae significantly increased the growth and absorption capacity of P. amurense. The seedling height, root diameter and root length were significantly higher than those of the control plants, which enhanced the seedling root activity and increased the ability of leaf to absorb NPK. The average number of seedlings of mosseae and G.diaphanum increased by nearly 20 cm compared with the control seedlings, and the root activity increased by 2.5-2.7 folds compared with the control. Arbuscular mycorrhizae promoted the growth and development of P. przewalskii, increased the photosynthetic efficiency of leaves, and promoted the uptake of mineral nutrients by root system. The content of N, P and K in leaves increased, of which the photosynthetic efficiency of G.diaphanum inoculation was most prominent. Photosynthesis The rate was 12.23μmol · m-2 · s-1. The research results can provide the technical basis for mycorrhizal breeding and resource conservation of barberry.
