【Abstract】 The contents of proteins and amino acids in the seedlings of 14 cotton varieties were analysed. No obvious difference was observed between resistant and susceptible genotypes to fusarium wilt (Fusarium vasinfectun Atk.) in their total protein contents, while the seedlings of resistant genotypes contained more soluble proteins than susceptible ones. Inoculated with the pathogen, the resistant genotype seedlings had 15%～19% lower total free amino acids while the susceptible genotypes had 13%～20% higher total free amino acids than the non inoculated controls, and total amino acids decreased in both resistant and susceptible genotypes.更多还原
