中文摘要：

以田间栽培的6个葡萄品种（矢福罗莎、维多利亚、红宝石无核、红霞、藤稔、早熟红无核）为试材，观察根系丛枝菌根的发育状况及其与土壤有效磷的关系。结果表明，6个葡萄品种中以藤稔的菌根侵染状况和结构发育状况较好，维多利亚的较差。丛枝菌根的结构发育在〈0．4mm和〉2．0mm粗度根段上较差，在0．4-0．8mm、0．8-1．2mm、1．6．2．0mm根段粗度上分别观察到侵入点、丛枝数和泡囊数最高。葡萄丛枝菌根的发育与根际土壤有效磷没有表现显著相关关系。

英文摘要：

Experiment was conducted in field with 6 grape cuhivars including Yatomi Rosa,Victoria, Flame Seedless,Red Glow, Fujiminori and Ruby for studying the arbuscular mucorrhizal status and analyzing the correlation between available soil P and arbuscular mycorrhizae. The results showed that in these 6 grape cuhivars, Fujiminori cultivar expressed better mycorrhizal colonization and structure development but Victoria cultivar had worse development. Mycorrhizal structure developed less on the root thickness of 〈0.4 to 〉2.0 mm, some entry dots, versicles and arbuscles were found much on the root thickness of 0.4 to 0.8 mm, 0.8-1.2 mm and 1.6 to 2.0 mm. There was no significant correlation between mycorrhizal devepment and soil available P.
