Abstract
Plants of muskmelon(cv. Yindi) were sprayed with chitosan at 1 g / L separately at one week before flower, young fruit period, fruit enlarging period and netting period. Results showed that preharvest chitosan treatment improved the activity of defensive-related enzymes of muskmelons. With the increase of the spray times, the activity of polyphenoloxidase(PPO),peroxidase(POD), phenylalanine ammonialyase(PAL) were enhanced, pathogenesis-related protein β-1,3-glucanase(GLU) and chitinase(CHT) activities were improved as well. The four times cumulation of spraying had the most obvious effect on the increase of the muskmelons activity of defensive-related enzymes.
