本研究选用6个不同生长势的葡萄品种扦插苗为材料,通过盆栽接种试验,探讨摩西球囊霉(Glomus mosseae,Gm)对参试材料丛枝菌根真菌(AMF)侵染率及菌丝酶活性的影响,并分析AMF对试材无机营养吸收能力的影响。结果表明,接种Gm能够显著提高参试材料的AMF侵染率,且强生长势品种的侵染率显著高于弱生长势品种;接种后能够不同程度地提高试材的菌丝酶(ALP和SDH)活性,6个品种的菌丝酶活性大小依次为玫瑰蜜>早黑蜜>水晶>维拉莎>京秀>红地球;丛枝菌根的形成对各试材无机营养的吸收均有影响;其中,对促进大量元素吸收的效果优于微量元素,使试材根、茎、叶中的大量元素含量均显著高于CK,但却出现部分试材的微量元素含量低于CK的情况,其中以茎最为典型;接种对不同品种无机营养吸收的贡献率表现各异,相对而言弱生长势品种的贡献率大于强生长势品种。
In this study, six different growth potential grape seedlings were used as materials to investigate the effects of Glomus mosseae (Gm) on the infection rate of arbuscular mycorrhizal fungi (AMF) and mycelium Enzyme activity, and analyze the AMF on inorganic nutrient absorption capacity of the test material. The results showed that inoculation with Gm could significantly improve the AMF infection rate of the tested materials, and the infection rates of the strong growing potential varieties were significantly higher than those of the weak growing potential varieties. After inoculation, the mycelial enzyme (ALP and SDH ). The mycelial activity of six cultivars were as follows: rose honey> black honey> crystal> verasha> Jingxiu> red globe; the formation of arbuscular mycorrhizas affected the absorption of inorganic nutrients ; Among them, to promote the absorption of a large number of elements better than trace elements, so that a large number of elements in the roots, stems and leaves were significantly higher than CK, but there are some of the trace elements in the content of CK lower than the case, Among them, the stems were the most typical. Inoculation showed different contribution rates to the inorganic nutrient absorption of different varieties, while the contribution rate of weakly growing varieties was greater than that of strong growing ones.
