通过对中棉、陆地棉（抗、感棉花枯萎病品种）和海岛棉根系分泌物中葡萄糖、蔗糖及不同氨基酸成分和含量的测定表明：棉花感病品种根分泌物中葡萄糖和蔗糖的含量是抗病品种的２～３倍；在所测定的６个棉花品种中共含有１２种氨基酸，其种类和含量依棉花品种不同而异。不同糖的浓度对菌落生长速度影响不大，但影响菌落的旺盛程度及色素的形成。在所测定的１２种氨基酸中，丙氨酸、天冬氨酸、组氨酸、脯氨酸和异亮氨酸对棉枯萎菌的生长略有刺激作用，精氨酸、谷氨酸、赖氨酸、丝氨酸则有抑制作用。
Through the determination of the composition and content of glucose, sucrose and different amino acids in the cotton (Upland cotton), upland cotton (resistance to cotton fusarium wilt) and the root exudates of G. barbadense, the content of glucose and sucrose in root exudates of cotton susceptible varieties was Resistant varieties 2 to 3 times; measured in 6 cotton varieties contain a total of 12 kinds of amino acids, the type and content varies with cotton varieties vary. The concentration of different sugars had little effect on the growth rate of colonies, but affected the exuberant degree of colony and the formation of pigment. Among the 12 amino acids tested, alanine, aspartic acid, histidine, proline and isoleucine slightly stimulated the growth of cotton fescue. Arginine, glutamic acid, Amino acids, serine inhibition.
