摘要:

绣球(Hydrangea macrophylla)因其丰富的花色和花型而成为重要的园林观赏植物,但杭州夏季高温高湿的气候限制了其应用。因此,本研究通过人工气候箱模拟高温高湿复合环境,结合形态观测和生理指标测定,系统评价了8个绣球的耐湿热性。结果显示,在高温下纱织小姐的可溶性糖、脯氨酸积累更快,可溶性蛋白含量更高,超氧化物歧化酶(SOD)和过氧化物酶(POD)活性的上升幅度更大,进而增强了其渗透保护和活性氧清除能力;甜蜜幻想的丙二醛(MDA)含量更低,膜脂过氧化程度较轻,显示出了不同的耐胁迫策略。综上,纱织小姐具有更强的酶活性提升能力,表现出更强的耐湿热性适应性。本研究筛选出了适配杭州湿热气候的绣球品种,为耐湿热绣球品种的栽培管理与遗传改良奠定了基础。

Abstract:

Hydrangea macrophylla is an important ornamental plant due to its rich flower colors and diverse forms. However, its application in Hangzhou is limited by the high temperature and humidity in summer. Present study systematically evaluated the heat and humidity tolerance of eight H. macrophylla cultivars by simulating a high-temperature and high-humidity environment using the artificial climate chambers, combined with morphological observation and physiological index measurements. The results showed that Miss Saori exhibited faster accumulation of soluble sugars and proline, higher soluble protein content, and greater increases in SOD and POD activities under high temperatures, enhancing its osmotic regulation and reactive oxygen species scavenging capacity. In contrast, Sweet Fantasy displayed lower MDA content, indicating milder membrane lipid peroxidation and a different stress resistance strategy. In conclusion, Miss Saori demonstrated stronger heat and humidity adaptability due to its superior enzyme activity enhancement. Present study not only provides H. macrophylla cultivars suitable for hot and humid climate in Hangzhou, but also provides a foundation for the cultivation management and genetic improvement of heat- and humidity- tolerant hydrangea varieties.
