| 摘 要： | 为研究根际pH对檀香的生长和寄主偏好性的影响,用便携式酸度计检测了中国科学院华南植物园檀香园及附近的61种植物根部的pH值,并考察了檀香在不同pH梯度下的生长情况.结果表明,几乎所有优良寄主根部的pH值均为50～6.0;在pH 5.5的培养条件下,檀香茎和根的长度明显比在其他pH值下的要长.这说明檀香生长的最佳根际pH...

| Abstract: | The effects of rhizospheric pH value of host on growth of Indian sandalwood (Santalum album L.) and preference to host were studied. Rhizospheric pH values of 61 hosts of S. album were measured by using portable precise acidimeter, and the growth status of S. album under a gradient rhizospheric pH were observed. The results showed that rhizospheric pH of almost all fine hosts ranged from 5.0 to 6.0, and the root length and shoot height of S. album grown at pH 5.5 were significantly higher than those grown at other pHs. It was suggested that the optimum pH of Indian sandalwood was 5.5. It is helpful to choose a fine host of S. album. |
