摘要
Abstract
Preharvest and postharvest application of Harpin was evaluated for its ability to induce resistance in muskmelon fruit and control rots. Preharvest treatments were 30 mg L-1, 60 mg L-1 Harpin or 1 mg L-1 Imazalil either 1 week or 1 day before harvest.The CK was untreated. Fruit were then inoculated with Fusarium semitectum or Trichothecium roseum 48 h after harvest,and stored at 23 ± 1℃, RH (relative humidity) 50-60% for 4 d. All treatments were effective in reducing the lesion area with 60 mg L-1 Harpin the most effectively. No treatments inhibited infection rate. Postharvest treatment was fruit dips of 30 mg L-1, 60 mg L-1 Harpin, 0.1 mg L-1 Imazalil. Fruit were inoculated with F. semitectum or T. roseum 24, 72, 120 or 168 h after treatment, and stored at 23 ± 1 ℃, RH 50-60% for 4 days. All treatments were effective in reducing the lesion area with 60 mg L-1 Harpin the most effectively. No treatments inhibited the infection rate. Postharvest Harpin treatment induced the peroxidase activity increase, peroxidase activity reached maximum after 8 d and the activation lasted at least 10 d.关键词
