Effects of arbuscular mycorrhizal fungi colonization on Bt corn growth
摘要
Abstract
Taking two Bt-corns 5422Btl ( Bt11 ) and 5422CBCL ( Mon810) that express Cry1Ab and their near-isogenic non-Bt corn (5422) as test materials, this paper studied the effects of inoculating Glomus mosseae on their growth. There was an obvious difference in the colonization rate of G. mosseae on the three corn varieties, and the general trend was 5422Bt1 ＞ 5422CBCL ＞ 5422. Inoculating G. mosseae promoted corn growth, and the effect varied with corn variety and its development stage. For variety 5422, its aboveground biomass and total dry weight at bell stage increased significantly; for variety 5422Btl, its leaf number and stem diameter at jointing stage and its leaf number, stem diameter, aboveground biomass, and total dry weight at bell stage were significantly higher than those of the control; and for variety 5422CBCL, its leaf number at jointing stage and its underground biomass at bell stage also increased significantly. The AMF-dependence and the AMF-inoculation effect on the three corn varieties were in the order of 5422Bt1 ＞ 5422CBCL ＞ 5422, suggesting that the two Bt-corns had better compatibility with G. mosseae. Compared with non Bt-corn, Bt-corn had stronger positive responses in its growth to the AMF inoculation.关键词
