| 摘 要： | 以叶片和果实病情指数为依据,研究了海南省7个芒果品种的炭疽痛生态位.结果表明,芒果炭疽病对叶片和果实的侵染效应差别较小,对时间、空间和营养3资源的利用程度不尽相同.时间生态位宽度指数(平均值)分别为0.117 7和0.263 9,说明芒果炭疽病在时间维上的利用程度小,其发生和发展具有条件性;空间生态位宽度指数(平均值)为0.704 7和0.904 0,病菌能够充分利用各空问资源;营养生态宽度指数为0.666 2和0.579 6.说明病菌可以侵染各品种,但品种间的抗病性有较明显差异,台农1号抗病性较强,红芒6号、凯特和白玉较易感病. |

| Abstract: | This paper studied niche of mango anthracnose according to disease index of leaf and fruit about seven cultivars in Hainan province. The results showed that effect of infection on leaf and fruit was finely discriminating, while the using capability to resource was different. The average of temporal niche breadth of mango anthracnose was 0.1177 according to disease index of leaf ,while 0.2639 according to disease index of fruit. That suggested that breaking out of mango anthracnose was conditional. The avera... |
