Abstract:
The biological characteristics of the main pathogen causing the postharvest diseases of melon cultivar ‘Yujinxiang’ (honeydew type) in Ningxia province semi arid climate area were studied.The effects of temperature,pH,illumination on the mycelium growth and the germination of conidiophores of the pathogen were explored in order to provide a theoretical basis for the prevention and control of the melon postharvest diseases.The results indicated that the temperature range was 10～35℃ for the mycelia growth and conidiophores of  Trichothecium roseum,for the Fusarium spp.and Alternaria alternate,it was 10～35℃.The optimal temperature was 25℃.For  Trichothecium roseum,the range of pH was 4～10 for mycelia growth,4～8 for conidiophores germination,while optimal pH was 6.For Fusarium spp.and Alternaria alternate,it was 3～10 for mycelia growth,2～10 for conidiophores germination.The optimal pH was 7 for mycelium growth and the germination of conidiophores.Light
hardly affected the growth of these fungi mycelia growth and conidiophores germination.
