张氏红山茶(Camellia changii Ye)是珍稀濒危植物,最早发现于中国广东省阳春市鹅凰嶂自然保护区。其具有抗逆性强、四季开花、花大色艳等特点,是培育茶花新品种非常珍贵的种质资源。目前,现存的野生原种数量极其稀少,濒临灭绝边缘,因此对张氏红山茶的更深入研究对于拯救濒危植物、保存珍贵种质资源具有重要意义。本文系统地综述20余年来张氏红山茶的生物学特性、遗传繁育、濒危机制等方面的的研究进展,并对前人的研究成果做了相应补充,提出一些看法和推测,为张氏红山茶的更深入研究起到一定的导向或参考作用。

Camellia changii Ye is a rare and endangered plant which was discovered in E'huangzhang nature reserve,located at Yangchun City,Guangdong Province.It is a very good germplasm resource for breeding new varieties because of the strong stress resistance,perpetual bloom,bigger and colorful flower and so on.Since there exists rarely wild stock seed which is almost endangered,the further study for Camellia changii Ye is very important to rescue endangered plants and preserve precious germplasm resources.The research progress on biological characteristics,genetic and breeding,endangered mechanism of Camellia changii Ye in the past 20 years is systematically reviewed in this paper.Moreover,corresponding supplement to the former research achievements is given,and some opinions and speculations are also proposed,which is referenced to the further research on Camellia changii Ye.
