摘要
以枇杷为试材，对抗枇杷根腐病病菌的6株枇杷主干内生真菌进行生物学特性研究。结果表明：PDA、PSA和CA培养基为最适合各参试菌株菌丝生长的培养基；葡萄糖、蔗糖、麦芽糖为最适合各参试菌株菌丝生长的碳源；牛肉膏、酵母膏、蛋白胨为最适合各参试菌株茵丝生长的氮源；25-30℃最适合各参试菌株菌丝生长；所有参试菌株适宜菌丝生长的pH值为中性或偏碱性；全光照处理有利于参试菌株菌丝生长。
Taking Eriobotrya japonica as material,the biological characteristics of 6 Eriobotrya japonica endophyte strains significantly antagonized pathogen of Eriobotrya japonica root rot were studied. The results showed that the proper growth mediums of the strains were PDA, PSA and CA. In the tested carbon sources, the proper carbon sources were glucose,sucrose and maltose. In the tested nitrogen sources, the proper nitrogen sources were beef extract,yeast extract and peptone. And the proper pH value of all the tested strains was neutral or alkaline,the proper temperature was 25-30 degrees celsius and illumination was beneficial for mycelium growth. This conclusion provided theoretical parameter for the fermentation.
