摘　　要：采用实地调查和实验室分析相结合的方法,对藤县大果红山茶(Cammellia magnocarpa)形态特征与主要经济性状进行调查分析。结果表明,藤县大果红山茶茶树高5～10 m,树皮呈灰色,表面光滑;果实为蒴果,呈青红色,果形有球形、卵形、梨形和盘形等;单株平均有鲜果62个,单果重337.11～720.83 g;按茶树种植密度1110株/ha计,每公顷可产鲜果32767.20 kg,产油1028.02 kg。说明藤县大果红山茶原始茶林经济性状优良,遗传多样性丰富,具有广阔的开发应用前景。A field investigation combined with laboratory analysis was conducted to study the morphological and main economical characteristics of C. magnocarpa in Tengxian. The height of C. magnocarpa was 5-10 m and the color of bark was gray with smooth surface. The fruit was in the form of greenish red capsule and its shape varied from spherical, ovate, puriform to dish like. The average number of fruits per plant was 60 and the weight of a single fruit ranged from 337.1- 483.0 g. At the planting density of 1110 plants per ha, the average yield of fresh fruits was estimated as 32767.20 kg per ha and the average yield of oil as 1028.02 kg per ha. The results revealed great genetic diversity of C. magnocarpa with varying economic charactersistics. Therefore, it can be explored for further utilization in breeding programs.
