【摘要】：地被菊(Chrysanthemum morifolium Ramat.cv.)不僅具有較強的觀賞價值,而且具有很強的抗逆性。在沈陽地區(qū)乃至東北地區(qū)的綠化、美化中起到了十分重要的作用,但是我們對地被菊觀賞價值和抗逆性的評價,未進行過完整的定量分析,尤其對地被菊系列品種群的系統(tǒng)評價,未進行過定量研究�；诖�,本文從觀賞性和抗逆性角度,對沈陽農(nóng)業(yè)大學自主選育的20個地被菊品種進行系統(tǒng)評價。本文運用層次分析法相關函數(shù)進行綜合評價,得出評價地被菊性狀指標的權重值,然后通過建立理想品種,利用灰色關聯(lián)度法得出各個品種的灰色關聯(lián)度,按照與理想品種之間的關聯(lián)程度設定劃分等級的評價標準,對20個地被菊品種進行等級劃分,本研究取得的主要結果有:(1)、調(diào)查結果表明①地被菊品種雙粉匙、粉磐石、金殿堂、436、wy29、十月荷花、早玉盤、晚妝深粉、橙黃磐石、黃磐石可歸為一類,這些品種特點是:花色純正,重瓣或花型較特殊,花徑均比較大,生長勢強健,但是生長適應性一般。②地被菊品種天柱山1號、夕陽紅可歸為一類,這些品種特點是:生長勢較強,生長適應性比較強,觀賞價值也較高,但是花型、花色一般。③地被菊品種鴻運、中國紅、MT010、越16、黃鶯、08-55越可歸為一類,這些品種特點是:鴻運的幅高比較小,花徑較小;中國紅的花序數(shù)較少,重瓣性較差;MT010的株高較高;越16株高較高,冠幅較小,幅高比較小;黃鶯的株高較高,冠幅較小,花序數(shù)少;08-55越的花序數(shù)較少,抗病性差。這些品種生長狀況普通,觀賞價值一般。(2)、通過調(diào)查株高、冠幅、幅高比、開花整齊度、花序數(shù)、始花時間、花期、盛花期、花色、花徑、著花繁密度、重瓣性、生長勢、繁殖系數(shù)、萌動性、抗倒伏能力、抗病蟲能力這17個評價指標,運用層次分析法和灰色關聯(lián)度分析法得出綜合評價結果。①綜合評價值為Ⅰ級的地被菊品種有10種,分別為:雙粉匙、粉磐石、金殿堂、436、wy29、十月荷花、早玉盤、晚妝深粉、橙黃磐石、黃磐石。②綜合評價值為Ⅱ級的地被菊品種有2種,分別為:天柱山1號、夕陽紅。③綜合評價值為Ⅲ級的地被菊品種有6種,分別為:鴻運、中國紅、MT010、越16、黃鶯、08-55 越。④綜合評價值為Ⅳ級的地被菊品種有2種,分別為:國慶紅、喇叭瓣。
[Abstract]:Chrysanthemum morifolium Ramat.cv. not only has strong ornamental value, but also has strong resistance to adversity. It plays a very important role in greening and beautifying in Shenyang and even northeast China. However, we have not evaluated the ornamental value and adversity resistance of ground bed chrysanthemum, especially to the ground. Based on the view of ornamental and adversity, this paper makes a systematic evaluation of 20 species of chrysanthemum from the angle of ornamental and adversity. This paper makes a comprehensive evaluation by the correlation function of the analytic hierarchy process (AHP), and obtains the weight value of the evaluation of the index of the property of the chrysanthemum, and then through the evaluation. After establishing the ideal variety, the grey correlation degree of various varieties was obtained by the grey correlation degree method. According to the evaluation criteria of the grade between the ideal varieties and the degree of correlation between the ideal varieties, the grade of 20 ground covered chrysanthemum varieties was classified. The main results of this study were as follows: (1) the results of the survey showed that (1) the two flour spoons, the powder rock, and the gold of the ground covered chrysanthemum were found. Palace, 436, wy29, October lotus, early jade plate, late makeup deep powder, orange pan rock, yellow rock can be classified as a class, these varieties are characterized by pure flower color, double or flower type is more special, the flower diameter is relatively large, growth potential strong, but the growth adaptability of Mount Tianzhu 1, sunset red can be classified as a class, these varieties characteristic is: Growth Strong potential, strong growth adaptability and high ornamental value, but flower type, flower color is general. (3) ground by chrysanthemum variety Hongyun, Chinese red, MT010, the more 16, the yellow warbler, 08-55 can be classified as one category, the characteristics are: Hongyun is relatively small, small diameter; the number of red flowers in China is less, MT010 is higher, the higher the height of the plant; the 16 plant height is higher. Higher, smaller crown, smaller height, the yellow warbler has higher plant height, smaller crown width, less inflorescence, less inflorescence of 08-55 and poor disease resistance. These varieties have common growth conditions and general ornamental value. (2) through investigation of plant height, crown width, height ratio, flower neatness, inflorescence number, flowering time, florescence, flowering period, flower color, flower diameter, flower propagation density The 17 evaluation indexes, such as double sex, birth growth, reproduction coefficient, germination, resistance to lodging and disease resistant and insect resistance, have been evaluated by analytic hierarchy process and grey correlation analysis. (1) 10 species of ground cover chrysanthemum varieties with a comprehensive evaluation value of grade I are: Double powder, powder rock, golden palace, 436, wy29, October lotus, early jade plate and late. There are 2 kinds of chrysanthemum varieties that are evaluated as grade II, respectively: Mount Tianzhu 1 and sunset red. (3) there are 6 species of ground covered chrysanthemum with comprehensive evaluation value of grade III, respectively: Hongyun, China red, MT010, 16, yellow warbler, and 08-55. (4) there are 2 kinds of ground covered chrysanthemum varieties with comprehensive evaluation value of grade IV, respectively national day. Red, trumpet.
