摘要：【目的】探明不同家系木姜叶柯(Lithocarpus polystachyus)的叶功能性状和主要活性成分含量,并分析两者的相关性,为木姜叶柯经济生态型优良种质选择和遗传改良提供科学依据。【方法】以采自9个种源16个家系的木姜叶柯叶片为材料,测定其形态特征指标、养分含量和主要活性成分含量,并比较其差异。【结果】家系来源对木姜叶柯叶片的形态特征、养分含量及主要活性成分含量具有显著影响,且叶片功能性状和主要活性成分间存在显著相关性。湖南城步家系(LNT2)表现出最优的资源利用效率,其叶干质量(0.25 g)、叶体积(550.75 mm^(3))和叶干物质含量(34.62%)均最高,而比叶面积(110.97 cm^(2)/g)最小;江西安福家系(AF)的根皮苷含量(27.93 mg/g)最高;湖南绥宁家系(C2)的三叶苷含量(37.12 mg/g)和根皮素含量(3.68 mg/g)最高;二氢查耳酮含量较高的3个家系分别是AF(60.08 mg/g)、C2(54.92 mg/g)和江西分宜家系(NZ,44.88 mg/g)。叶主要活性成分含量在家系间的变异幅度较大,其中,根皮苷和三叶苷含量的变异系数最大,分别为48.12%和45.93%。【结论】木姜叶柯家系间叶功能性状与活性成分变异丰富。湖南城步家系(LNT2)资源利用效率高,湖南绥宁(C2)、江西分宜(NZ)和江西安福家系(AF)活性成分含量突出,是优质种质选育的理想材料。
[Purpose]To investigate the functional traits and content of main active components in leaves of Lithocarpus litseifolius among different families,as well as their interrelationships,providing a scientific basis for the selection and genetic improvement of economically and ecologically superior germplasm of L.litseifolius.[Methods]Leaf samples were collected from 16 families originating from nine provenances of L.litseifolius.The morphological traits,nutrient contents,and main active component contents of the samples were measured,and their differences were analyzed.[Results]The family origin significantly influenced the leaf morphological traits,nutrient contents,and main active components contents of L.litseifolius.Significant correlations were also found between leaf functional traits and the main active components.The Hunan Chengbu family(LNT2)exhibited the highest resource use efficiency,possessing the highest leaf dry weight(0.25 g),leaf volume(550.75 mm^(3)),and leaf dry matter content(34.62%),while having the lowest specific leaf area(110.97 cm^(2)/g).The Jiangxi Anfu family(AF)had the highest phloridzin content(27.93 mg/g).The Hunan Suining family(C2)showed the highest trilobatin content(37.12 mg/g)and phloretin content(3.68 mg/g).The families with higher dihydrochalcone content were AF(60.08 mg/g),C2(54.92 mg/g),and Jiangxi Fenyi family(NZ,44.88 mg/g).The variation range of the main active components contents in leaves among the families was relatively large,and the coefficient of variation of phloridzin and trilobatin content was the largest,which was 48.12%and 45.93%,respectively.[Conclusion]Substantial variation exists in functional traits and active components among L.litseifolius families.The Hunan Chengbu family(LNT2)demonstrates high resource use efficiency,the Hunan Suining(C2),Jiangxi Fenyi(NZ),and Jiangxi Anfu(AF)families exhibit outstanding active component contents,making them promising candidates for breeding superior germplasm.
