摘要
为筛选适宜太原露地应用的优良观赏萱草材料,对不同来源地引种萱草开展了物候期、生长表现和形态特征观测,从适应性和观赏性2个层面评价了6种萱草的园林应用价值,并对其18个主要性状进行了相关性分析,探讨了太原地区萱草引种的评价指标。结果表明,6种供试萱草的适应性由高到低排序为H1>H2>H3>H5>H6>H4;观赏性由高到低排序为H6>H4>H1>H5>H2>H3。相关性分析结果表明,萱草茎叶和花部的数量性状间部分显著相关或极显著相关。从园林应用价值方面考虑,在露地中,H1和H5均表现出最佳的观赏价值和适应性,是太原地区萱草栽培应用的首选。
To select the excellent Hemerocallis materials which adapt to open field in Taiyuan area,the value of landscape architecture of six Hemerocallis was evaluated with the two levels of adaptability and ornamental,mainly including phenological phase,growth performance and morphological characteristics.In addition,the correlation analysis of 18 main characters of Hemerocallis was carried out,then the evaluation indexes of Hemerocallis introduction in Taiyuan was discussed.The results showed that the adaptability of the six tested Hemerocallis was H1>H2>H3>H5>H6>H4.The ornamental value from high to low was H6>H4>H1>H5>H2>H3.The correlation analysis showed that there were significant correlations or extremely significant correlations between the stems,leaves and flowers characteristics of Hemerocallis.Considering the landscape application,H1 and H5 were the most suitable materials for cultivation in Taiyuan because of both high value of ornamental and adaptability.
