爱玉子雌性品系主要农艺性状的灰色关联度分析

目的]通过评估爱玉子雌性品系的综合价值,筛选出优质的品系进行示范与推广,为爱玉子高产栽培提供科学依据。方法]应用灰色理论关联度分析法综合评估栽种爱玉子10个雌性品系的叶面积、花序数、花序长、花序宽、果胶含量、果胶酶活性6个主要的农艺性状。结果]大洋T84的加权关联度最大,综合品质最高,W13、新25的综合品质较好,适合在福建地区推广与示范,其余品系较差。结论]不同爱玉子雌性品系之间的个体性状和综合性状差异较大,应根据具体情况对品系加以筛选后推广栽培。

Research on the Main Agronomic Traits of Female Ficus awkeotsang Makino Line with Grey Relational Analysis

Objective] The scientific basis of Ficus awkeotsang Makino cultivation was provided through the evaluation of the integrated value of its female line and the selection of its elite line for demonstration and extension. Method] Six major agronomic traits,such as the leaf area,the number,length and width of inflorescence,the content of pectin,the activity of pectinase,of 10 female Ficus awkeotsang Makino plants were assessed with the method of grey correlation analysis. Results] The weighted correlation of the line Dayang T84 was largest with the best integrated quality; W13 and Xin 25 with better comprehensive quality,being suited to the extension and demonstration in the Fujian Province; and the other lines were poor. Conclusion] There were quite difference in the individual character and comprehensive trait of different female awkeotsang lines and the extension and cultivation the Ficus awkeotsang Makino line should depend on the actual circumstances after its screening.
