摘要
广东省南昆山独特的地理环境孕育了珍稀天然无咖啡碱毛叶茶资源。为摸清‘南昆山毛叶茶’野生资源现状并为其保护及利用提供理论参考,对野生‘南昆山毛叶茶’进行了系统调查及性状研究。结果发现,‘南昆山毛叶茶’野生资源主要呈聚集群落形式存在,群落与群落间相距较远。所调查的104份野生毛叶茶资源均属乔木型或小乔木型,树冠较小,分支较为聚拢向上;叶型变异丰富,多属大叶;叶片较厚,栅栏组织排列紧密;新梢嫩芽茸毛密而顺长;绝大部分野生毛叶茶可可碱含量较高,咖啡碱含量较低,非表型儿茶素GCG和C是主导儿茶素组分。
The unique geographical environment of Nankun Mountain in Guangdong Province has nurtured rare natural caffeine free wild Camellia ptilophylla resources.In order to understand the current situation of the resources and provide theoretical reference for their protection and utilization,we conducted a systematic investigation and trait study on them.The results showed that Camellia ptilophylla mainly exist in the form of aggregated communities,with communities far apart from each other..A total of 104 wild Camellia ptilophylla were investigated all belong to arbor or small arbor type,with smaller tree crowns and more concentrated and upward branches;Rich variation in leaf shape,mostly belonging to large leaves;The leaves are thick and the palisade tissue is arranged tightly;The tender buds of new shoots have dense and smooth hairs;.Most of wild Camellia ptilophylla have a higher content of theobromine and a lower content of caffeine,,with non phenotypic catechins GCG and C being the dominant catechin components.
