| 摘 要： | 在室内以甲霜灵为化学对照,80%乙醇为空白对照测试了菊花乙醇提取物对番茄晚疫病菌(Phytophthora infestans)菌丝生长和孢子囊萌发的抑制作用,以及光照、温度对菊花提取物抑菌效果的影响.结果表明:菊花的乙醇提取物抑制番茄晚疫病菌菌丝生长的有效中浓度为稀释470倍,抑制孢子囊萌发的有效中浓度为稀释1 055倍;光照强度在6 000～80 000 lx范围内,温度在40～90℃范围内,菊花提取物的抑菌效果和化学药剂甲霜灵差异不显著.

| Abstract: | The effect of Dendronthema orifolium(Ramat)Tzvel ethanol extract on hyphae growth,spore germination were measured in comparison with 80% ethanol metalaxyl and which was used as control,and the effect of radiant intensity and temperature on the inhibitory efficacy of Dendronthema orifolium(Ramat)Tzvel ethanol extract were also tested.The results showed that the ED50 of Dendronthema orifolium(Ramat)Tzvel ethanol extract to hyphae growth and spore germination was 470 times dilution and 1 055 times dilution,rad... |
