摘要
用不灭菌的沙质黄潮土和建筑河沙作为生长基质,施加一定量稀释的 Hoagland 营养液,在盆栽条件下比较了来源于扦插苗和实生苗的不同植物对 VA 菌根的依赖性。结果表明除了一般被认为不形成 VA 菌根的菊花外,其余植物接种萄根后,不论株高,地上部分、地下部分鲜重和侵染率都大于不接种的对照植物。各种植物对菌根的依赖程度的大小依次为:葡萄、月季、白三叶草、芦笋、非洲紫罗兰、矮牵牛花,玉米、棉花、大豆、烟草、花生、西红柿、绿豆、百合。
Mycorrhizal dependency of various kinds of plants was estimated in pot cultures.Seeds or cuttings inoculated with Glomus spp.were grown in unsterilized sandy fluvo-aquic soil or sand,fertilized with dilute Hoagland's solution.Results showed that the weight of shoot and root of all mycorrhizal seedlings was significantly greater than that of uninoculated seedlings except chrysanthemum which was generally recognized as a nonmycorrhizal family.Mycor- rhizal dependency of different plants decreased in the following order:grape,China rose, white clover,asparagus,violet,petunia,corn,cotton,soybean,tobacco,peanut,tomato,mung- bean,lily and chrysanthemum.Mycorrhizal inoculation also enhanced the flowering of China rose and terminal bud growth of pomegranate.There was no correlation between the percen- rage of mycorrhizal infection and mycorrhizal dependency,although all plants were infected after inoculation.
