摘要
本试验通过对青钱柳10个无性系在不同子代测定林中的树高、地径、一级分枝数量、最大梢长、叶长、叶宽及叶形指数等生长指标进行调查,对其叶片中总黄酮、总萜类、多糖、锌及铁元素含量进行测定,并采用隶属函数法对各项评价指标进行综合评价,以期评选出表现优良的青钱柳无性系,为江西省青钱柳产业发展提供良好的种质资源。结果表明,10个供试无性系的树高均值为105.42 cm,分布在60.1~152.0 cm之间;地径均值为12.69 mm,分布在6.8~19.72 mm之间;一级分枝数量平均为5.7个,分布在3~10个之间;最大梢长的均值为38.47 cm,分布在14.6~79.0 cm之间;叶长均值为11.97 cm,分布在6.7~17.9 cm之间;叶宽均值为3.76 cm,分布在2.3~5.6 cm之间;叶形指数均值为3.23,分布在2.0937~4.3703之间。总黄酮含量均值为14.15%,分布在10.61%~19.74%之间;总萜类含量均值为1.20%,分布在0.53%~2.16%之间;多糖含量均值为3.1 g·kg^(-1),分布在0.9~11.9 g·kg^(-1)之间;锌元素含量均值为52.11 mg·kg^(-1),分布在29.2~78 mg·kg^(-1)之间;铁元素含量均值为102.04 mg·kg^(-1),分布在74.2~142 mg·kg^(-1)之间。根据各指标的隶属函数值对供试无性系进行综合评价,结果显示无性系YF08的各指标平均隶属函数值为0.5225,排名第一;其次为无性系XS18,达到0.4991;排第三位的为无性系WN40,其平均隶属函数值为0.4901。该结果表明该三个无性系的综合表现是所有供试无性系中最为优良的,存在进一步选育的空间。
In this study,the tree height,ground diameter,number of primary branches,maximum tip length,leaf length,leaf width,leaf shape index and the contents of total flavonoids,total terpenes,polysaccharides,zinc and iron in leaves of 10 Cyclocaria sinensis clones were investigated and analyzed in different progeny.In order to select the clones with good performance and provide good germplasm resources for the development of Cyclocchiana industry in Jiangxi Province.The results showed that the average tree height of the 10 tested clones was 105.42 cm,which distributed in the range from 60.1 to 152.0 cm.The average ground diameter was 12.69 mm,which distributed in the range from 6.8 to 19.72 mm.The average number of primary branches was 5.7,which distributed from 3 to 10.The average maximum tip length was 38.47 cm,and the distribution was from 14.6 to 79.0 cm.The average leaf length was 11.97 cm,and the distribution was from 6.7 to 17.9 cm.The average leaf width was 3.76 cm,the distribution was from 2.3 to 5.6 cm.The average leaf shape index was 3.23,which ranged from 2.0937 to 4.3703.The mean content of the total flavonoids was 14.15%,with a distribution from 10.61%to 19.74%,the mean content of the total terpenoids was 1.20%,with a distribution form 0.53%to 2.16%.The mean content of polysaccharides was 3.1 g·kg^(-1),with a distribution from 0.9 to 11.9 g·kg^(-1).The average content of zinc was 52.11 mg·kg^(-1),which ranged from 29.2 to 78 mg·kg^(-1).The average content of iron was 102.04 mg·kg^(-1),which ranged from 74.2 to 142 mg·kg^(-1),According to the membership function value of each index,the results of comprehensive evaluation of the tested clones showed that the average membership function value of each index of YF08 was 0.5225.The second was XS18,which reached 0.4991.In third place was WN40,whose average membership function value was 0.4901.The results showed that the combined performance of the three clones was the best among all the clones tested.
