中文摘要:
      探索了不同温度、光照、pH、营养等条件对贵州栀子叶枯病病原菌菌丝生长、孢子萌发(或产孢)的影响,以期系统掌握该病原菌的生物学特性,为栀子叶枯病防治提供理论依据。研究结果表明:栀子叶枯病菌菌丝在10~35℃温度范围内均能生长,孢子均能萌发,菌丝生长和孢子萌发最适温度为25℃;连续光照或光暗交替有利于菌丝生长和产孢;在pH 5~6之间,是病原菌菌丝生长和孢子萌发最适pH;该病原菌适宜于PDA、PSA 等培养基袁单糖、双糖、多糖等碳源以及有机氮和无机氮均能利用。
英文摘要:
      This paper aimed to study the biological characteristics of the pathogen (Pestalotiopsis maculiformans)causing leaf blight on Gardenia jasminoides Eills in Guizhou province, the effects of temperature, illumination, pH, nutritional condition on the mycelium growth and the germination of conidiospore (sporulation) of the pathogen were explored, the study of this paper systematically made a research on the biological characteristics of Pestalotiopsis maculiformans, it could provid a theoretical basis for the prevention and control of the Gardenia disease. The temperature range was 10~35℃for the mycelia growth and the conidiospore germination of the pathogen, the optimal temperature for mycelia growth and conidiospore germination was 25℃. The mycelia grows well and sporulation under the full light or light/darkalternation. The optimal pH was 5~6 for mycelia growth and conidiospore germination and the optimal culture medium for mycelia growth and conidiospore were PDA, PSA and so on, The pathogen could use monosaccharide, disaccharide, polysaccharide,and the pathogen could use organic and inorganic nitrogen.
