In order to help ZJU-China( Zhejiang University) detect the inhibitory effect of Trichoderma on the process of Phytophthora making inroads into tobacco, we did a lot of work as follows:
Respectively inoculated Phytophthora and Trichoderma into tissue culture tobacco with differentiated root, stem and leaf.
Specific method of inoculation: dig a some amount of medium (about 0.5cmX0.5cm), then use about 6ml up water to rinse its mycelia and spores, finally take 1ml solution from it, then pour it into the tissue culture bottle which with tobacco.
Trichoderma, Phytophthora, Trichoderma and Phytophthora, the control (up water) four groups inoculated at the same time, each with three repetitions. After inoculation, these plants were placed at 25℃ in incubator. We took photos everyday from different but fixed angles at 10:00 and 22:00 to record their growth status and health condition. We feed back the state of the plants regularly. After 15 days, we can saw these plants changed obviously. On the 30th day, we took them out of the bottles, got their fresh weight, then put into the dryer 105℃ for 0.5h.80℃ for 10h to get their dry weight.
