| Abstract: |
| Disease-resistance induced by phytoextraction is one of the new disease-prevention methods. Natural virus-resistant substances from plants are hot spots of researches on bio-prevention in recent years. Two varieties of muskmelon (Cucumis melo L.) Yindi and Kalakesai were exposed under different inductors to investigate the responses of photosynthetic characteristics and fruit yield and quality in Gansu Province. The results indicated that the inductor could significantly enhance net photosynthetic rate(Pn) and stomatal conductance (Gs) of the two varieties in the process of growth and development of melon and it could improve the yield and solubility of fruit. The Pn increased by 39.6% and 32.0% respectively in Yindi and Kalakesai under the treatment of BTH+SA at the earl
y flowering stage. Under the treatment before harvest, the yield and solubility of fruit was enhanced significantly. The effect was the best when BTH+SA was sprayed at early flowering stage, in which the yield and solubility of fruit of Yindi increased by 22.6% and 9.0%, and those of Kalakesai increased by 22.6% and 9% compared with control. The effect of all the treatments was more remarkable on the solubility of fruit of Kalakesai than that of Yindi. There was no signifiant difference either between twice and once spraying, or between mixed inductor and single inductor. |
