荸荠秆枯菌(CylindrosporiumeleocharidisLentz)生长发育温度8~35℃,最适于菌丝体生长、产孢的温度为25~30℃,20~28℃孢子萌芽率较高。致死温度46℃10min。病菌在RH75%以上生长良好,其产孢量则随湿度升高而增加。RH81%以上孢子可以发芽,饱和湿度再加水滴时发芽率最高。PH4.50~9.13均较适于病菌生长,产孢量则以在PH6.94~9.13时较多,PH4.20~7.60较适宜孢子发芽。连续黑光灯照射有促进孢子形成和菌丝体旺盛生长的作用。此菌对多种单糖、双糖和多糖都能利用,以蜜二糖、麦芽糖、葡萄糖等产孢量较多。适于病菌生长和产孢的氮源是甘氨酸、DL-α-氨基丙酸和氨基乙酸,脲素较差。
The growth and development temperature of CylindrosporiumeleocharidisLentz was 8 ~ 35 ℃, which was the most suitable for mycelial growth. The temperature of sporulation was 25 ~ 30 ℃, and the spore germination rate was higher at 20 ~ 28 ℃. Lethal temperature 46 ℃ 10min. The germs grew well above RH75%, while their sporulation increased with the increase of humidity. RH81% Spores can germinate, saturated humidity and water droplets when the highest germination rate. PH4.50 ~ 9.13 were more suitable for the growth of germs, while the amount of spores is more in PH6.94 ~ 9.13, PH4.20 ~ 7.60 more suitable for spore germination. Continuous black light irradiation to promote the formation of spores and mycelium strong growth. The bacteria on a variety of monosaccharides, disaccharides and polysaccharides can be used to melibiose, maltose, glucose and other sporulation more. Nitrogen sources suitable for germ growth and sporulation are glycine, DL-α-aminopropionic acid and glycine, and urea is poor.
