福建省主要适生观赏草品种盆栽观赏性评价

Evaluation of Ornamental Value of Main Potted Ornamental Grass Varieties Suitable for Fujian Province

通过对福建省主要适生观赏草品种的盆栽观赏性评价,筛选出盆栽观赏性价值高的观赏草,使其加快投入花卉市场,丰富市场上的观赏草盆栽品种,促进中国观赏草盆栽事业的发展。测定了花色、叶色、株高、叶片数、观赏期等5个指标,采用灰色关联度分析法对16种观赏草盆栽的株型紧凑度、花序观赏性、叶色、植株观赏性、整体搭配效果、观赏期、生长势7个性状进行了观赏性评价。综合评价比较高的品种有粉黛乱子草,其与理想种的关联度为0. 650 5;其次是金叶石菖蒲、金钱菖蒲和黄金姬菖蒲,它们与理想草种的关联度比较接近,分别为0. 638 3、0. 630 3和0. 629 4,具有较好的综合性状;关联度较低的是细叶芒和花叶蒲苇,其与理想种的关联度为0. 488 7和0. 484 5。

The evaluation of ornamental value of potted ornamental grass varieties suitable for Fujian Province was carried out to screen out the ornamental grasses with the high potted ornamental value,in order to provide technical supports for the quick screening of ornamental grass cultivars suitable for potted planting,to put them into flower markets,to enrich ornamental potted varieties on the market and further promote the development of ornamental potted grass in China.Five indicators of flower color,leaf color,plant height,leaf number and the ornamental period were measured,and then 7 characters of 16 ornamental grass pots were measured using the grey correlation analysis method,including the degree of plant compactness,inflorescence,leaf color,plant ornamental quality,overall collocation effect,ornamental period and the growth potential quality.The whitefly grasshopper stood out in the comprehensive evaluation with the association degree to the ideal species at 0.6505,which was followed by stone calamus with the gold leaf,money calamus and gold jirushipu.Their associations to ideal grass species were relatively close,i.e.,0.6383,0.6303 and 0.6294,respectively,which indicated that they have a good overall character.Lepidopteris glauca and P.sinica were the two species with lower degree of association,whose associations to ideal species were respectively 0.4887 and 0.4845.
