Abstract:
Seeds of a small fruit watermelon cultivar ‘Heijin’ and a big fruit watermelon cultivar ‘Shuangsebingqilin’ were used as test materials，using single factor variable method，the temperature condition for small fruit watermelon seed germination was preliminarily optimized and the effect of biological control fungus Trichoderma koningiopsis T-51 on the germination of watermelon seeds was evaluated.The results showed the small fruit watermelon was preferred to germinating better in warm conditions，the seed soaking at 30-35 ℃，and germinating at 32-34 ℃ get the best germination.The watermelon seeds soaked in 1×107 conidia?mL-1 of T-51 conidia suspension for 8-10 hours，the germinative energy of ‘Heijin’ seed was up to 59% when T-51 treated，and the germination index (GI) and seed vigor index (VI) were increased by 14.12% and 25.17%，respectively.The germinative energy of ‘Shuangsebingqilin’ 10-year-old seed was increased from 13% to 29% after T-51 treated，and the GI and VI were increased by 48.61% and 103.73%，respectively，which showed significantly promotion.The above results indicated that，in early maturing cultivation of watermelon，using T.koningiopsis T-51 conidia suspension to soak watermelon seed could accelerate seed germination，increase seed vigor，make the seedling growth tidy and strong，and save labor and cost.These results also indicated that T-51 could promote watermelon old seed germination，which was important for the recovery of watermelon genitive resources and the improvement of seeds utilization.
