| １９９２～１９９４年将在河北、河南采集的枣缩果病病果，经柯赫法则程序诊断及对分离菌鉴定、明确导致枣缩果病的病原有盾壳霉属的一种真菌Ｃｏｎｉｏｔｈｙｒｉｕｍｓｐ．、细链隔孢菌ＡｌｔｅｒｎａｒｉａｔｅｎｕｉｓＮｅｅｓ．、半知菌亚门无孢目有隔有色丝状菌３种弱寄生真菌和１种细菌。以上４种菌年累计分离率依次为１４．９０％、１２．６９％、１１．４７％、１０．６６％；而这４种菌占已出现菌落比分别为３０．２８％、２５．７９％、２３．３０％以及２０．６３％。 |
| 英文摘要: |
| Diseased fruits of Jujube fruit shrink were collected in eight counties of Hebei and Henan Provinces in 1992 to 1994. Pathogens isolated from diseased fruits were diagnosed and identified according to Koch’s prin-ciples. The pathogens are Coniothyrium sp., Alternaria tenuis Nees,a fungus belonging to Agonomycetes and a kind of bacterium. The former three are weak pathogenic fungi different occurrence frequencies were obtained in dif-ferent years and locations. In 1992～1994,the total iselating rates of the four pathogens were 14.9%, 12. 69%,11. 47%and 10.66% respectively. The proportions for the four pathogens were 30.28%, 25. 79%, 23. 30%and 20.63%respotivrly. |
