Abstract:

Based on the fern resources collected and preserved in Shenzhen Fairy Lake Botanical Garden,the evaluation system was constructed using the analytic hierarchy process to comprehensively evaluate the ornamental value of 42 species of fern with potential for garden application. The results showed that among the primary indicators,leaves accounted for the largest weight,which was 46.73%,followed by habitat conditions(27.72%),rhizomes(16.01%),and spore sac group(9.54%). Among the secondary indicators,leaf color,vigor,overall leaf morphology,and stem direction accounted for more than 10.00% of the total weight of the ornamental value of fern,which had a great influence on the evaluation results. Among them,the total weight of leaf color reached 19.98%,which was the key indicator affecting the ornamental value of fern. According to the indicator weights and scoring criteria,the 42 species of fern were comprehensively scored and divided into four levels:Level I(score>4.0)was for species with high ornamental value,totaling 7 species;Level Ⅱ(3.5<score≤4.0)was for species with relatively high ornamental value,totaling 11 species;Level Ⅲ(3.0<score≤3.5)was for species with average ornamental value,totaling 15 species;Level Ⅳ(score≤3.0)was for species with low ornamental value,totaling 9 species. In addition,the results of cluster analysis showed that seven Class I fern species,including Blechnum gibbumNephrolepis cordifoliaSphaeropteris lepiferaBrainea insignisGymnosphaera henryiNephrolepis biserrata,and Alsophila gigantea,all grew well and performed outstandingly in the ornamental traits of their leaves and rhizomes,which had good prospects for garden application and could be developed and utilized on a large scale.
