摘要 收集27個玉簪屬品種進(jìn)行形態(tài)生長指標(biāo)、栽植成活率及生長分株數(shù)的觀測記錄，通過成活率高低及分株能力初次篩選到20種，篩選的玉簪品種分為4個葉色類型，即黃色葉、花色葉、綠色葉、藍(lán)色葉。耐陰試驗(yàn)表明，結(jié)合品種形態(tài)生長指標(biāo)最終篩選到12種，確定4個葉色類型及每個類型適合推廣應(yīng)用的品種。

Abstract 27 species of Hosta were collected to observe and record the morphological growth index， planting survival rate and the number of growing branches. Through the survival rate and branch ability， 20 species were screened for the first time. The screened Hosta varieties were divided into four leaf color types， namely yellow leaf type， flower color leaf type， green leaf type and blue leaf type. The shade tolerance test showed that combined with the morphological growth index of varieties， 12 varieties were selected， and four leaf color types and varieties suitable for popularization and application of each type were determined.

近幾年，沈陽市園林科學(xué)研究院先后從國內(nèi)外引進(jìn)27個玉簪屬品種，與普通的玉簪品種相比具有葉色類型豐富、觀賞期長、植株高大健壯、抗病性強(qiáng)等特點(diǎn)[1]。（剩余2452字）
