【摘要】：地被菊(Chrysanthemum morifolium Ramat.cv.)不仅具有较强的观赏价值,而且具有很强的抗逆性。在沈阳地区乃至东北地区的绿化、美化中起到了十分重要的作用,但是我们对地被菊观赏价值和抗逆性的评价,未进行过完整的定量分析,尤其对地被菊系列品种群的系统评价,未进行过定量研究。基于此,本文从观赏性和抗逆性角度,对沈阳农业大学自主选育的20个地被菊品种进行系统评价。本文运用层次分析法相关函数进行综合评价,得出评价地被菊性状指标的权重值,然后通过建立理想品种,利用灰色关联度法得出各个品种的灰色关联度,按照与理想品种之间的关联程度设定划分等级的评价标准,对20个地被菊品种进行等级划分,本研究取得的主要结果有:(1)、调查结果表明①地被菊品种双粉匙、粉磐石、金殿堂、436、wy29、十月荷花、早玉盘、晚妆深粉、橙黄磐石、黄磐石可归为一类,这些品种特点是:花色纯正,重瓣或花型较特殊,花径均比较大,生长势强健,但是生长适应性一般。②地被菊品种天柱山1号、夕阳红可归为一类,这些品种特点是:生长势较强,生长适应性比较强,观赏价值也较高,但是花型、花色一般。③地被菊品种鸿运、中国红、MT010、越16、黄莺、08-55越可归为一类,这些品种特点是:鸿运的幅高比较小,花径较小;中国红的花序数较少,重瓣性较差;MT010的株高较高;越16株高较高,冠幅较小,幅高比较小;黄莺的株高较高,冠幅较小,花序数少;08-55越的花序数较少,抗病性差。这些品种生长状况普通,观赏价值一般。(2)、通过调查株高、冠幅、幅高比、开花整齐度、花序数、始花时间、花期、盛花期、花色、花径、着花繁密度、重瓣性、生长势、繁殖系数、萌动性、抗倒伏能力、抗病虫能力这17个评价指标,运用层次分析法和灰色关联度分析法得出综合评价结果。①综合评价值为Ⅰ级的地被菊品种有10种,分别为:双粉匙、粉磐石、金殿堂、436、wy29、十月荷花、早玉盘、晚妆深粉、橙黄磐石、黄磐石。②综合评价值为Ⅱ级的地被菊品种有2种,分别为:天柱山1号、夕阳红。③综合评价值为Ⅲ级的地被菊品种有6种,分别为:鸿运、中国红、MT010、越16、黄莺、08-55 越。④综合评价值为Ⅳ级的地被菊品种有2种,分别为:国庆红、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.
