| 摘 要： | 通过测定热处理对潜伏侵染于芒果果实中的胶胞炭疽菌(Colletotrichum gloeosporioides Penz.)和香蕉果实中的芭蕉炭疽菌C.musae(Berk.& Curt.)Arx.]离体培养菌的生长、繁殖和致病性的影响,结果表明:当温度达55℃和60℃,时间20 min时,对菌体的生长和孢子萌发可起明显抑制或杀伤作用,并降低其致病性。2种炭疽菌中,芭蕉炭疽菌比胶胞炭疽菌对热更敏感。作者认为,果实采后热处理时,应根据果实种类和不同菌,采用不同的处理温度和时间,才能得到更好的效果。

| Abstract: | The tests on effects of heat treatment were conducted on mycelial growth,spore germination and pathogenicity of Colletotrichum musae (Berk.& Curt.)Arx.from banana fruit and C.gloeosporioides Penz.from mango fruit in latent infection.The results showed that mycelial growth and spore germination were suppressed while the pathogenicity were reduced when the pathogens were subjected to 55℃ and 60℃ for 20 mins.C.musae was more susceptible to heat than C.gloeosporioides was.Therefore,the authors suggested that the heating duration and the temperature for postharvest treatment should be set according to the types of fruit and pathogen. |
