| 摘 要： | 研究干旱胁迫下天彭牡丹的生理生化响应及观赏特性变化,为天彭牡丹培育关键技术体系提供理论依据和技术支持.以盆栽天彭牡丹红丹兰为试材,采用称重控水法,设置对照、轻度胁迫、中度胁迫和量度胁迫4个水平,于破绽期、初花期、盛花期、谢花期、花后期Ⅰ、花后期Ⅱ6个时期进行各项生理生化及观赏特性指标测定.随着干旱胁迫强度的增加和时间的延长,天彭牡丹叶片脯氨酸含量、可溶性糖含量、可溶性蛋白含量均呈逐渐增大的趋势且花期变长；而叶片相对含水量逐渐降低,花朵大小逐渐变小；对天彭牡丹花瓣的花色素苷含量也有显著影响(LS＞CK＞MS＞HS).天彭牡丹抗旱能力较强,各指标对中度和重度胁迫均敏感,适当的水分管理可提高天彭牡丹的观赏价值.

| Abstract: | Effect of drought stress on physiological-biochemical and ornamental characteristics changes of Tianpeng Tree Peony was studied for key technology of breeding and planting.With potted Paeonia suffruticosa 'Hongdan Lan' as material,the treatment was artificially controlled by weighting and setting four levels,such as control level,light drought stress level,middle drought stress level,heavy drought stress level.The physiological-biochemical indexes of leaves and ornamental characteristics were tested at bud-... |
