摘要
桑椹菌核病是制约果桑生产的一个瓶颈性问题,目前多采用化学药剂对其进行防治.试验用红外高温热敏对桑椹菌核病菌的子囊盘进行照射,设立3个不同处理时间,即30s,45s,60s,研究红外线对子囊孢子杀灭的瞬时温度.结果表明,当红外高温热敏装置对其子囊盘照射30s和45s可使子囊盘变形皱缩,但不能使子囊盘内的子囊孢子灭活;照射60s,其温度上升为125℃,不仅能使子囊盘明显变形皱缩,而且可以有效地杀灭子囊盘内的子囊孢子.其试验结果可为工业上生产手持式红外高温热敏装置提供生物学实验依据.
Mulberry fruit sclerotiniosis is a bottleneck problem during mulberry tree growth, and chemical agents are usually used for its control. In a research reported in this paper, infrared high-temperature ther- mistor was employed to irradiate the apothecia of the pathogenic fungi of mulberry fruit sclerotiniosis for 30s, 45s and 60s, and the instantaneous temperature for killing the ascospores was determined. Deforma- tion and shrinkage of the apothecia were noticed after they were exposed to the infrared high-temperature thermistor device for 30s or 45s, but the ascospores in them were not inactivated. The temperature rose to 125 ℃ after 60s exposure, and obvious deformation and shrinkage of the apothecia occurred and the asco- spores in them were killed. The data presented herein can provide a biological experimental basis for the industrial production of handheld infrared high-temperature thermistor devices.
