丛枝菌根真菌对超旱生植物刺山柑生长及相关生理指标的影响

Effects of Arbuscular Mycorrhiza Fungi on Growth and Some Physiological Indices of Capparis spinosa

采用盆栽试验研究接种丛枝菌根真菌(arbuscular mycorrhiza fungi简称AMF)摩西球囊霉(Glomus mosseae,G.m)和地表球囊霉(Glomus versiforme,G.v)对超旱生植物刺山柑(Capparis spinosa L.)幼苗生长及相关生理指标的影响。结果表明:①不同AM真菌的侵染率不同,以G.m的侵染率最高,为39.15%;②与未接菌刺山柑植株相比,接种G.m和G.v均能够明显促进刺山柑植株生长,显著提高植株生物量,尤其是根部生长量;③随着菌根侵染率的提高,接种AM真菌提高了刺山柑植株叶片叶绿素、可溶性糖和脯氨酸含量,降低了叶片丙二醛(MDA)含量,叶片超氧化物歧化酶(SOD)、过氧化物酶(POD)、过氧化氢酶(CAT)活性增强,植株地上部分和根系的N、P含量显著增加;④接种AM真菌能够明显促进刺山柑的生长,2种AM真菌接种处理中以摩西球囊霉接种效应更为明显。

The effects of AM fungi （Glomus mosseae, Glomus versiforme） on growth and physiological indices of Capparis spinosa in the pot culture were studied. The results showed that the infection rate of different AM fungi was different, and the highest infection rate of G. m was 39.15% ; compared with the control group, inoculation of G. m and G. v could obviously promote the growth of Capparis spinosa, plant biomass was significantly increased, especially the roots; with the mycorrhizal infection rate increasing, the inoculation of AM fungi improved the content of chlorophyll, soluble sugar and proline, reduced the content of MDA in leaves, and the activities of SOD, POD and CAT were enhanced. The contents of N and P in aerial part and roots were significantly increased; two kinds of AM fungal inoculation could obviously promote the growth of Capparis spinosa, the effect of inoculation of Glomus mosseae was more obvious.
