摘要
为掌握武夷山不同区位茶园的茶树叶片功能性状,分析比较不同茶树对环境空间变异的影响,揭示植物对环境的适应机制,以正岩、半岩、洲茶分布区的105、水仙及肉桂3个品种茶为研究对象,采用叶厚度、叶面积、叶干质量、比叶面积、叶干物质含量等指标评价各品种茶的叶片功能性状。结果表明:水仙的叶片厚度为0.55~1.04mm;叶面积为648.00~3118.00mm;比叶面积为7348.79~32956.81mm^2/g;叶干物质含量为8.84%~39.59%;相对水分亏缺为0.54%~9.01%。肉桂的叶片厚度为0.40~0.78mm;叶面积为329.00~1801.00mm;比叶面积为6745.21~20955.22mm^2/g;叶干物质含量为21.93%~41.49%;相对水分亏缺为0.68%~32.74%。105的叶片厚度为0.56~0.79mm;叶面积为383.00~1211.00mm;比叶面积为7469.10~16305.73mm^2/g;叶干物质含量为22.59%~36.54%;相对水分亏缺为1.56%~66.04%。由相关性可知,水仙、肉桂、105茶树种叶片的比叶面积(SLA)与中干物质含量LDMC成负相关,且相关性在0.01上表示极为显著,叶面积AR与茶叶片厚度TH成正相关,与比叶面积SLA、相对水分缺失RMD成负相关。
In order to understand the functional characteristics of tea leaves in different tea gardens in Wuyishan, analyze and compare the effects of different tea plants on the spatial variability of the environment, and reveal the adaptive mechanism of plants to the environment, Narcissus, Cinnamomum cassia and 105 tea varieties in Zhengyan, Hemiyan and Zhoucha tea districts were taken as the research objects, and leaf thickness, leaf area, leaf dry mass, specific leaf area and leaf dry matter content were used to evaluate them. Functional traits of leaves of tea varieties. The results showed that the leaf thickness was 0.55 to 1.04 mm, the leaf area was 648.00 to 3 118.00 mm, the specific leaf area was 7348.79 to 32 956.81 mm^2/g, the leaf dry matter content was 8.84% to 39.59%, and the relative water deficit was 0.54% to 9.01%. The leaf thickness of Cinnamomum Cassia was 0.40 to 0.78 mm, the leaf area was 329.00 to 1801.00 mm, the specific leaf area was 6745.21 to 20955.22 mm^2/g, the leaf dry matter content was 21.93% to 41.49%, and the relative water deficit was 0.68% to 32.74%. The leaf thickness of 105 was 0.56 to 0.79 mm, leaf area was 383.00 to 1 211.00 mm, specific leaf area was 7 469.10 to 16 305.73 mm^2/g, leaf dry matter content was 22.59% to 36.54%, relative water deficit was 1.56% to 66.04%. According to the correlation, SLA in leaves of Narcissus, Cinnamomum cassia and 105 tea species was negatively correlated with LDMC, and the correlation was extremely significant at0.01. AR was positively correlated with TH and negatively correlated with SLA and RMD.
