Influence of Rhizospheric pH Value of Host on Growth of Indian Sandalwood and Preference to Host

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.
