日照市引种藤本月季品种综合评价

Comprehensive Evaluation of Varieties of Climbing Rose in Rizhao City

以引进的18个藤本月季品种为研究对象,测定株高、冠幅、花径、花瓣数、单朵花期、花期、生长速度、抗性8个指标,采用单因素方差和灰色关联度分析进行综合评价,筛选出适宜在日照市推广应用的藤本月季品种。结果表明:红色龙沙宝石的株高为438.12 cm、冠幅251.20 cm、花瓣数107.00片、生长速度0.49 cm/d,且均显著(P<0.05)高于其余品种,抗性得分最高,达97.00分。花期排名前5位依次为安吉拉、红色龙沙宝石、西方大地、橘红火焰、夏令营,在120~130 d。单朵花期时长均在5.00~8.00 d,其中西方大地最长,达8.00 d。欢笑格鲁吉亚、我的心、澳洲黄金3个品种的多个性状显著(P<0.05)低于其他品种,其中我的心生长速度最慢,澳洲黄金抗性得分最低,仅70.00分。灰色关联度分析结果显示,表现最好的为红色龙沙宝石和西方大地,且红色龙沙宝石长势最旺、抗性最好,红色龙沙宝石与理想参考品种关联度高达0.9000以上,适宜在日照地区栽植;加权关联度表现为橘红火焰>藤宝贝>御用马车>大游行>安吉拉>藤彩虹>花魂>夏令营>伊蕾莎斯特,均高于0.6000,建议可在日照市推广应用;光谱、海格瑞、黄金庆典表现一般,加权关联度在0.5500~0.6000;詹姆斯高威、澳洲黄金、欢笑格鲁吉亚、我的心表现差,与理性参考品种关联度低于0.5200,不适宜在日照市绿化中应用。

In this study,the 18 different types of climbing rose as the research object,among the plant height,crown width,flower diameter,number of petals,single flower period,flowering period,growth rate,and resistance was detected,a single-factor analysis of variance and gray correlation analysis was used for comprehensive evaluation,and the suitable varieties of climbing rose for popularization and application in Rizhao City were selected.The results showed that the plant height of Red Eden Rose was 438.12 cm,the crown width was 251.20 cm,the number of petals was 107,and the growth rate of 0.49cm/d,which was significantly higher than other varieties(P<0.05),and the resistance score was up to 97 points.The top five in the order of flowering were Angela>Red Eden Rose>Westerland>Cl Rainbow's End>Maidy,which lasted between 120-130 days.The flowering period of a single flower was 5-8 days,of which the highest was 8 days in the Westerland.Teasing Georgia,Mon Coeur,and Australian Gold has significantly lower performance in multiple traits(P<0.05)than other varieties.Among them,Mon Coeur grew the slowest and the Australian gold resistance score was 70.The Grey Relational Analysis demonstrated that both the Red Eden Rose and Westerland have the well performances,and Red Eden Rose was the most prosperous and resistant,and the correlation with the ideal reference variety was over 0.9,which is very suitable for planting in Rizhao area.The order of good performance was Orange Fire>Meilivoine>Parkdirektor Riggers>Parade>Angela>climbing Rainbow>Chivalry>Maidy>Ines Sastre,and the weighted correlation was higher than 0.6.It is recommended to promote the application in Rizhao,Spectra,Highgrove,and Golden Celebration performed averagely,with a correlation between 0.55-0.6.James Galway,Australian Gold,Teasing Georgia,and Mon Coeur performed the worst,with a correlation of less than 0.52 with a rational reference variety,which is not suitable for application in the greening of Rizhao City.
