Abstract:
‘Jingxin No.4’ watermelon was used as test material.The effect of dibutyl phthalate on photosynthesis and Fusarium wilt of watermelon was studied under greenhouse conditions.The results showed that 1.0 mL?L-1 dibutyl phthalate had notable impact on promoting growth,net photosynthetic rate,transpiration rate,intercellular CO2 concentration and stomatal conductance,it also could reduce the incidence of watermelon wilt disease index and had good control effects(37.5%).When the concentration was up to 2.0 mL?L-1,the growth net photosynthetic rate,transpiration rate,intercellular CO2 concentration and stomatal conductance of watermelon seedlings largely decreased.In addition,2.0 mL?L-1 dibutyl phthalate had little positive efficacy(9.4%) on inhibition of Fusarium wilt.There would be a positive effect on prevention the watermelon Fusarium wilt to use dibutyl phthalate appropriately in production of watermelon.
