摘要
本文研究了主要生态条件对ＶＡ菌根真菌侵染烟草的影响。结果表明：山东植烟土壤类型中，以轻壤质普通棕壤最利于ＶＡ菌根真菌的侵染和增殖，其次为中壤质普通棕壤、轻壤质淋溶褐土、中壤质淋溶褐土和轻壤质普通褐土，此类土壤中ＶＡＭ真菌的种类多、数量大；而壤砂质粗骨棕壤、重壤质普通棕壤和重壤质淋溶褐土中ＶＡＭ真菌种类少，孢子量少。山东植烟土壤中ＶＡＭ真菌的优势属为球囊霉属Ｇｌｏｍｕｓ，少数为无轴囊霉属Ａｃａｕｌｏｓｐｏｒａ。常见种为摩西球囊霉Ｇ·ｍｏｓｅａｅ、透光球囊霉Ｇ·ｄｉａｐｈａｎｕｍ、幼套球囊霉Ｇ·ｅｔｕｎｉｃａｔｕｍ、近明球囊霉Ｇ·ｃｌａｒｏｉｄｅｕｍ和苏格兰球囊霉Ｇ·ｃａｌｅｄｏｎｉｕｍ等。不同类型的烟草与ＶＡＭ真菌的不同种之间存在一定选择性。烟草在不同生育期对ＶＡＭ真菌的侵染反应存在差异，以幼苗期接种反应最好。
The influence of ecological conditions to the infection of VAM fungi on tobacco roots was studied.The results showed that among the soil types in tobacco plantation area of shandong province,the light loamy burogem was the most favorable type for the infection and multiplication of the fungi.The next ones are medium loamy burogem,light loamy eluvial cinnamon soil,medium loamy eluvial cinnamon soll and light loamy cinnamon soil.In these soils the VAM fungi were in multi species and large quantities.There were fewer species and lesser spores of the fungi in loamy sandy fragnuntal burogem,heavy loamy burogem and heavy loamy eluvail cinnamon soil.The dominant genera of VAM fungi in tobacco plantation soil in Shandong was the Glomus and the Acaulospora was a minor genera.In the genera Glomus,G·mosseae,G·diaphanum,G·etunicatum,G·claroideum and G·caledonium were found ordinarily.Different types of tobacco had different preference for VAM fungi species.The infection of VAM fungi to tobacco plant were different in various growth stages of tobacco.Inoculation with VAM fungi in seeding stage made the best infection.
