Abstract
In greenhouse experiments, susceptible rice cultivar Yuanfengzao seedlings pretreated (in seedcoating) with Trichoderma harzianum NF9 exhibited moderate resistance against blast and bacterial leaf blight diseases after challenge inoculation with corresponding pathogens in comparison with susceptible response in seedlings untreated with the NF9 strain. Enzyme activities of PAL and POD in rice seedlings pretreated with the Trichoderma strain were increased after challenge inoculation with pathogens. At 120 h after inoculation with both Magnaporthe grisea strain SY1 and H16, POD activities in NF9 treated rice seedlings were significantly higher than that in untreated ones, whereas no significant diffrence in PAL activity were found between two ones. At 16 h and 96 h after inoculation with Xathomonas oryzae pv. oryzae CR1, and at 120 h after inoculation with X. oryzae pv. oryzae CR7 PAL activity in NF9 treated rice seedlings was significantly higher than that in untreated ones, whereas no significant diffrence in POD activity were found between two ones.
