| 摘要: |
| 1984～1986年通过田间自然鉴定和接种鉴定的方法,研究了原产我国的葡萄属18个种或变种,88个株系对黑痘病和白腐病的抗性。结果表明,这些种感染黑痘病的严重度为2.33～12.78％,在自然发病条件下不感白腐病,接种后白腐病的发病率为5.00～92.50％。种内不同株系间也存在着抗病和感病的类型。本文还对接种方法进行了探讨。研究表明,田间喷雾接种黑痘病的浓度为1×104孢子/ml;白腐病接种,田间以针刺果实2×105孢子/ml和室内以针刺果实2×106孢子/ml为宜。 |

| Abstract: |
| Resistance to grape anthracnose ( Sphaceloma ampelinum de Bary) and grape white rot ( Coniathyrium diplodiella ‘Speg.’ Sace) of 18 vitis species or varieties native to China ,including 88 clones, were studied by field evaluation and inoculation in 1984-1986. The results showed that the serious infection of these species by grape anthracnose was 2.33～12.78%. Although these species were not infected by grape White rot in field conditions, their incidence was 5.00～92.50% after inoculation. However ,there exist both resistant and susceptible biotypes in various clones within the same species. Also, this paper discusses the method of inoculation. The research revealed that the inoculation concentration of grape anthracnose was 1×104 Spores/ml by spraying in field. The suitable methods to inoculate grape white rot were acupuncture fruits with 2×105 Spores/ml in the fields and with 2×105 Spores/ml in the lab. |
