云南省曲靖市茶树种质资源调查与分析

Investigation and Analysis of Tea Germplasm Resources in Qujing City of Yunnan Province

对曲靖市内茶树资源进行了全面调查,发现曲靖市内茶种主要为茶和大厂茶及普洱茶等,在人工栽培与野生资源中均有分布,主要集中在曲靖市的富源县、师宗县、宣威市等地,区域特征明显。富源的大茶树分布较散,数量不多,以大厂茶为主;而师宗县大茶树分布较集中,数量较少,以大厂茶和茶为主。宣威市发现人工栽培的云南大叶茶种和小叶种茶曲靖市的大厂茶茎干粗大,有明显的花香,种子更新能力很强,树下有大量的幼苗生长,与其他地区的野生茶有明显差异,小叶种茶生长为乔木型,最大一株基部干径达96 cm,这在小叶种的记录中很罕见。

We investigated the tea germplasm resources in Qujing City,and found out that the main tea germplasm resources were Camellia sinensis,Camellia tachangensis and Camellia assamica,which were cultivated variety and wild resources.The tea germplasm resources mainly distributed in Fuyuan County,Shizong County and Xuanwei City,which showed obvious regional characteristics.The distribution of the big tea trees was relatively scattered and the quantity was not great in Fuyuan County,and tea germplasm was mainly Camellia tachangensis.The distribution of the big tea trees was relatively centralized and the quantity was not large in Shizong County,with the tea germplasm mainly Camellia tachangensis and Camellia sinensis.Larger leaf tea and leaflet tea had been found in Xuanwei City which belonged to Camellia sinensis.The individual of Camellia tachangensis was more larger with significant flower fragrance and strong seed renewal capacity in Qujing City.There were many seedlings growing under the big tea,which had significant differences with wild tea in other areas.Leaflet tea grows as bigger tree type,and maximum basal stem diameter was up to 96 cm,which was rare in the records of leaflet Camellia sinensis.
