青岛耐冬山茶的多样性：Ⅰ分布与形态变异

青岛崂山沿海岛屿有天然古山茶（ＣａｍｅｌｌｉａｊａｐｏｎｉｃａＬ．）分布，为山茶类植物中的耐寒类型，而被称作“耐冬”。耐冬古山茶个体间有形态上的明显变异。在野生状态下，产生了长蕊、少瓣、大花类等性状分化稳定的多种类型。青岛海岛耐冬山茶不仅有较高观赏价值，且可视为北方山茶的基因库。本文介绍了青岛耐冬山茶的分布与现状、生态生物学特征及其不同的变异类型，并对耐冬山茶多样性研究的意义作了简要说明。

Studies on the diversity of Naidong Camellia in Qingdao I Distribution and morphological variation

The wild ancient camellia (Camellia japonica L. ) is distributed on off-shore islands near Mount Lao inQingdao. As the cold-resistant tape,it was so-called "Naidong Camellia" by the local people. Accordingto the stable morphologlcal diversity,the Naidong Camellia can be divided into such groups as "long androecium","less petals","grand flower",etc. Naidong Camellia on off-shore islands in Qingdao has attracted much attention not only for the high appreciating value,but also for its being natural gene-poolof Camellia in North China. This paper dealt with the distribution of Naidong Camellia and its presentstatus,some ecobiotic traits and the morphological variation. The siginificance of the studies for NaidongCamellia diversity was also discussed.
