摘 要 ：诱导抗虫棉株对棉铃虫营养代谢功能的影响表明，胚轴切断法结合假单胞杆菌（Ｄ－２２５１）诱导处理的棉株可使棉铃虫相对生长率（ＲＧＲ）、相对取食量（ＲＣＲ）和近似消化率（ＡＤ）明显降低，分别降低２２．９５％、２６．１２％和２７．２３％，仅用胚轴切断法处理的棉株可使ＧＲＧ、ＲＣＲ和ＡＤ分别降低１７．２５％、２１．４４％和４．０９％。对诱导处理棉株体内植物多元酚和抗虫萜烯类的测定结果表明，经过胚轴切断法后，

Abstract:As the cotton plants has been cut off at plumular axis in 2 - 3 leaves stage and treated with the somatotropin ABT to promote the root regeneration, the relative growth rate (RGR), relative consumption rate (RCR) and approximate digestibility (AD) of cott
