丛枝菌根真菌对不同番茄品种幼苗素质的影响

Effect of Arbuscular Mycorrhizal Fungus on Qualities of Different Cultivars Tomato(Lycopersicon esculetum) Seedlings

采用盆栽试验的方法,于两个番茄品种旭日与金龙粉王育苗时分别接种G.mosseae,以明确该AM真菌在培育壮苗中的潜力。结果表明,G.mosseae显著的改善了两个番茄品种幼苗的素质,但是金龙粉王较旭日的接种效应明显。旭日与金龙粉王接种G.mosseae后,壮苗指数分别为相应不接种处理的2.38倍与3.49倍。菌根化幼苗的健壮生长在一定程度上依赖于G.mosseae对氮、磷养分吸收的显著促进作用。G.mosseae对氮吸收的菌根效应分别为47.50%与87.52%,对磷吸收的菌根效应分别为23.08%与64.74%。结果表明,将该AM真菌作为潜在的生物肥料引入设施番茄生产培育健壮幼苗是可行的。

To evaluate the potential of G.mosseae in improving the qualities of tomato seedlings,two cultivars Xuri and Jinlongfenwang were selected and pots experiment was conducted.The results indicated that the qualities of seedlings were both improved by inoculating with G.mosseae when the seeds were sown,but G.mosseae is much efficient in mycorrhizal effect on Jinlongfenwang seedlings,which is perfect symbiosis.The indexes of seedling′s quality are 2.38 and 3.49 times for Xuri and Jinlongfenwang respectively compared with the corresponding control.Mycorrhizal effectiveness′s of G.mosseae on N uptakes are 47.50% and 87.52%,and P uptakes are 23.08% and 64.74% for Xuri and Jinlongfenwang respectively.So it is practical to culture strong seedlings by apply G.mosseae as a potential biofertilizer in tomato production under protected conditions.
