摘要: 以上海自然气候条件为背景,选取群体花期、最大开放率、相对电导率、脯氨酸含量和光能利用率等5个与月季耐热性强弱密切相关的性状为指标,应用隶属函数分析、主成分分析和聚类分析对13个月季品种进行耐热性评价。结果表明:13个月季品种中阿比沙林卡(Rosa cv. ‘Abhisarika’)、矮仙女(Rosa cv. ‘Black Lady’)和红帽子(Rosa cv. ‘Red Hat’)属强耐热品种;欢笑(Rosa cv. ‘Bright Smile’)和拉维尼亚(Rosa cv. ‘Lawinia’)耐热性较强;金玛利(Rosa cv. ‘Golden Marie’)、Rosa cv. ‘Berrrcrd Buffet’(法)、Rosa cv. ‘Shocking Blue’(德)、我的选择(Rosa cv. ‘My choice’)和Rosa cv. ‘ANITA PEREIRE’(法)为中等耐热品种;橘红潮(Rosa cv. ‘Orange Wave’)、安吉拉(Rosa cv. ‘Angela’)和Rosa cv. ‘MY KONOS’ (法)耐热性较弱。建议在上海地区及江淮流域选择阿比沙林卡和欢笑进行推广应用。

Abstract: Based on the natural climate conditions of Shanghai, and taking flowering period, maximum flower opening rate, relative conductivity, proline content, and light utilization efficiency as the indices of rose heatresistance, the heatresistance of 13 rose varieties in the field was evaluated by the methods of subordinative function analysis, principal component analysis, and hierarchical cluster analysis. Among the 13 varieties, Rosa cv. ‘Abhisarika’, Rosa cv. ‘Black Lady’, and Rosa cv. ‘Red Hat’ had most stronger heatresistance, Rosa cv. ‘Bright Smile’ and Rosa cv. ‘Lawinia’ had stronger heatresistance, Rosa cv. ‘Golden Marie’, Rosa cv. ‘Berrrcrd Buffet’, Rosa cv. ‘Shocking Blue’, Rosa cv. ‘My choice’, and Rosa cv. ‘ANITA PEREIRE’ had midlevel heatresistance, and Rosa cv. ‘Orange Wave’, Rosa cv. ‘Angela’, and Rosa cv. ‘MY KONOS’ had low level heatresistance. Rosa cv. ‘Abhisarika’ and Rosa cv. ‘Bright Smile’ were recommended to be popularized in the gardens and parks in Shanghai and JiangHuai basins.
