中文摘要：

以2个不同转化事件的Bt玉米5422Bt1（Bt11）和5422CBCL（Mon810）及其同源常规玉米5422为对象,研究接种摩西球囊霉（Glomus mosseae）对Bt玉米与常规玉米生长的影响。结果表明：3个品系玉米接菌处理的菌根侵染率明显不同,菌根侵染各参数值总体呈现5422Bt1〉5422CBCL〉5422趋势;接种处理均促进了玉米的生长,其效应随玉米品系和生育期的不同而呈现差异,喇叭口期5422的地上部干重和总干重显著增加,拔节期5422Bt1的叶片数、茎粗以及喇叭口期的叶片数、茎粗、地上部干重、总干重显著高于对照,5422CBCL拔节期的叶片数和喇叭口期地下部干重增加显著;3个玉米品系菌根真菌依赖性与接菌效应为5422Bt1〉5422CBCL〉5422,2个Bt玉米品系与Glomus mosseae间的兼容性更好,接种处理对Bt玉米的生长促进作用强于常规玉米。

英文摘要：

Taking two Bt-corns 5422Bt1 （Bt11） and 5422CBCL （Mon810） that express Cry1Ab and their near-isogenic non-Bt corn （5422） as test materials,this pap er 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 co rn 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 weigh t at bell stage increased significantly;for variety 5422Btl,its leaf number an d stem diameter at jointing stage and its leaf number,stem diameter,abovegroun d biomass,and total dry weight at bell stage were significantly higher than tho se of the control;and for variety 5422CBCL,its leaf number at jointing stage a nd its underground biomass at bell stage also increased significantly.The AMF- dependence and the AMF-inoculation effect on the three corn varieties were in t he order of 5422Bt1 5422CBCL 5422,suggesting that the two Bt-corns had bet ter compatibility with G.mosseae.Compared with non Bt-corn,Bt-corn had stro nger positive responses in its growth to the AMF inoculation.
