摘　　要：对3种园林植物(矮牵牛、夏菊、藤本月季)的生长状况和耐热性生理指标进行了测定分析和指标评价研究。结果表明:其可溶性蛋白含量、脯氨酸含量和SOD酶活性与其耐热性呈正相关。在夏季高温高湿条件下,"普通矮牵牛"(常见品种)不能渡夏的原因是由于耐热性生理活性水平低,藤本月季不利于花芽分化和成花,菊花的开花习性主要受光周期的影响。Roses, the To investigate heat tolerance of three garden plants, Petunia, Summer chrysanthemum and Climbing growth phenotypes and physiological indices of heat tolerance were evaluated and measured respectively during the growth periods. The results showed that it was positively relative to heat tolerance for soluble protein and proline contents and the SOD activities. Under the summer environmental conditions with high temperature and humidity. ＇ Ordinary Petunia＇ failed to survive through the summer owing to low values of proline content and SOD activities, however it did harm to flower bud differentiation and flower formation in Climbing Roses and the photoperiod affected the flowering habit in Chrysanthemum.
