【摘要】 采用土培试验研究了不同施P水平下接种AM真菌摩西球囊霉 (Glomusmosseae)和苏格兰球囊霉(Glomuscaledonium )对烤烟不同叶位烟叶生长和化学成分的影响 .结果表明 ,接种AM真菌提高了烟草根系菌根侵染率 ,增加了烟叶总干重 ,其中对下位和上位烟叶效果明显 ,中位叶因菌种而异 .接种G .mosseae显著提高了中位叶总糖、烟碱、P、K含量和上位叶K含量 ,而接种G .caledonium则提高了下位叶总糖和上位叶总糖、还原糖、烟碱含量 ,促进了上、下位烟叶P含量的增加 .烟叶N、Mg、Fe、Zn含量因菌种和施P量不同而变化 .施P量为 0 .0 5 6～ 0 .112 g·kg-1土时接种效果最好 .更多还原

【Abstract】 The effects of AM fungi on the growth and chemical composition of tobacco leaf i n pot culture under different P levels was investigated by inoculation Glomus mosseae and G.caledonium .The results showed that mycorrhizal infection rat e could be promoted by inoculation,and increased total dry weight of tobacco lea f.Significant inoculation effect on leaf dry weight of lower and upper position was found. G.mosseae significantly increased the content of total sugar,nicot ine,P,K of middle position leaf and K of upper position leaf. G.caledonium si gnificantly increased the content of total sugar,P of lower position leaf and to tal sugar,reducing sugar,nicotine,P of upper position leaf.The content of N,Mg,F e and Zn of tobacco leaf was closed related to AM fungal species and P applied levels.Inoculation effect of AM fungi was the best under 0.056～0.112g P·kg -1 soil.更多还原
