%X By artificial pollination, dynamic survey of fruits setting rates, and analyzing the seed setting rates and fruits characters among different kinds of pollinations, four kinds of <em>Camellia</em> species were tested to study the characteristics of self-compatibility. The self-compatibility of four kinds of Camellia species was different, and the self-compatibility indexes of all materials were ranged in 0-0.29. The self-compatible indexes among four kinds of camellia species were <em>C.yuhsienensis</em> Hu(0.2888)&gt; <em>C.polyodonta</em> How(0.2511)&gt; <em>C.chekiangoleosa</em> Hu(0.1222)&gt; <em>C.semiserrata</em> Chi(0). All of the materials were considered as self-incompatible species because the self-compatibility of four kinds of Camellia species were less than 1. The average fruit setting rates and seed setting rates between different pollinations was outcrossing&gt; opening&gt; geitonogamy&gt; selfing. The character degree of self-pollination fruits was inferior to cross-pollination fruits. Fruits dropped faster after self-pollination, and fruit setting rates of cross-pollination was higher than that of self-pollination. Four kinds of Camellia species were completely self-incompatible. High self-incompatibility was the main factor causing flower and fruit dropping and low production.
