Abstract:
Taking processing tomato variety ‘TD4606’ as material,the biological characters and lesion sporulation of Fulvia fulva (Cooke) Ciferri from Shihezi city of Xinjiang province were preliminary studied.The results showed that the suitable temperature for lesion sporulation was 15~25℃,20℃ was the optimal temperature.Lesions hardly sporulated at 4℃ and 35℃.The optimum temperature for the colony growth was 20~25℃,and colony grew slowly below 15℃ or above 30℃.Lesions could sporulate under the relative humidity of 75% to 100%,and the quantity of sporulation increased with the time and the going up of humidity.The optimal pH of colony growth and lesion sporulation was 6.0.Lesions sporulated more and colonies grew faster in dark than in light.The ultraviolet rays inhabited the lesion sporulation and the colony growth.Spores mainly dispersed at night.The highest quantity of spores was found at 70 cm parts within the tomato plant from 20 cm to 90 cm.
