丛枝菌根菌对大田菜豆生长、产量及品质的影响

Effects of Arbuscular mycorrhizal fungi on growth,yield and quality of Phaseolus vulgaris L.in field

摘要: 1996～1997年研究了3种丛枝菌根菌Glomus mosseae(Nicol B & Gerd) Gerd & Trappe、 Glomus versiforme Karsten Berch和Gigaspora rosea Nicolson & Schenck对大田菜豆(Phaseolus vulgaris L.)生长、产量及品质的影响。结果表明，3种丛枝菌根菌均可显著增加菜豆植株N、P、K等元素和叶绿素含量，提高光合速率，促进菜豆植株生长，增加产量和豆荚粗蛋白与碳水化合物含量，改善豆荚品质。其中 Glomus versiforme的侵染率最高，促进菜豆生长和增产效应最显著。

Abstract: ffects of Arbuscular mycorrhizal(AM) fungi:Glomus mosseae(Nicol & Gerd) Gerd & Trappe,Glomus versiforme Karsten Berch and Gigaspora rosea Nicolson & Schenck on growth,yield and quality of Phaseolus vulgaris L.in field have been investigated from 1996 to 1997.Results show that inoculating it against AM fungi will increase the contents of N,P,K,Ca,Mg,Cu in Phaseolus vulgaris and its leaf chlorophyll,to enhance its transpiration rate,stomatal conductance and photosynthetic rate,and those to improve its growth and yield.Comparing the control to treatments,the contents of Vc,raw protein and carbonhydrate in pod are also increased.It suggests that Glomus versiforme should be the most effective in colonization and its benefit to Phaseolus vulgaris growth in field.
