藤本月季在衡陽地區(qū)的適應性綜合評價與篩選

摘 要：為了了解不同藤本月季品種在衡陽地區(qū)的生態(tài)適應性，篩選出在衡陽地區(qū)綜合表現(xiàn)優(yōu)異的藤本月季品種，運用層次分析法（AHP）對從云南省引進的15個藤本月季品種進行了適應性綜合評價和篩選。結果表明：建立的包括觀賞特性、生產(chǎn)特性和抗逆性共3個約束層和14個標準層性狀指標的衡陽地區(qū)藤本月季適應性綜合評價體系中，約束層指標權重大小為：觀賞特性（0.458）＞抗逆性（0.416）＞生產(chǎn)特性（0.126），說明觀賞特性和抗逆性是衡陽地區(qū)評價藤本月季適應性時需要考慮的首要因子；標準層14個因子的總排序依次為：抗熱性＞抗病蟲害＞植株蔓性＞花色＞單朵花期＞花徑＞生長勢＞花瓣質(zhì)地＞花瓣數(shù)量＞勤花性＞分枝數(shù)＞花香＞單株花量＞主莖粗，說明抗熱性是最重要的指標。根據(jù)適應性綜合評價值大小排序，紅色龍沙寶石、安吉拉、海格瑞和情書4個品種的適應性綜合評價等級為Ⅰ級，可以在衡陽地區(qū)推廣，其中適應性綜合評價值最高的品種紅色龍沙寶石十分適合應用于垂直綠化栽培；古董、格拉漢托馬斯、白色龍沙寶石和黃木香4個品種的適應性綜合評價等級為Ⅱ級，可作為備選推廣品種。

關鍵詞：藤本月季；適應性；層次分析法；綜合評價；篩選；衡陽地區(qū)

Abstract：The analytic hierarchy process （AHP） was employed to construct an evaluation system for comprehensively evaluating ecological adaptability of 15 climbing rose varieties introduced from Yunnan Province in Hengyang area， and screen out varieties with excellent comprehensive performance. The results showed that in the comprehensive evaluation system of adaptability whose constraint layer contained 3 indexes （ornamental characteristics， production characteristics and stress resistance） and criterion layer contained 14 indexes， the index weights at the constraint layer ranked as： ornamental characteristics （0.458）＞ stress resistance （0.416）＞ production characteristics （0.126）， illustrating that ornamental characteristics and stress resistance were the primary factors considered in the adaptability evaluation. The weights of 14 indexes of the standard layer were in the order： heat resistance＞ disease and pest resistance ＞ vine character＞ flower color ＞ single flower period ＞ flower diameter ＞ growing potential ＞ petal texture ＞ petal number ＞ flower frequency ＞ branch number ＞ floral fragrance ＞ flower number per plant ＞ stem thickness， demonstrating that heat resistance was the primary index. According to the evaluation results of adaptability， Clg Red Eden Rose， Angela， Highgrove and Billet Doux ranked grade I in climbing rose varieties， suitable for promotion in Hengyang area; among them， Clg Red Eden Rose scoring the highest was very suitable for vertical greenery. Antique， Graham Thomas， Clg White Eden Rose and Yellow Banks Rose ranked grade II， which can be used as spare materials for promotion.
