| 摘 要： | 通过盆栽试验,进行了4种藤本月季品种抗旱性的比较研究。在正常供水与水分胁迫条件下,分别测定与品种抗旱性有关的多项生理生化指标。把藤本月季各性状的抗旱系数作为衡量各单项抗旱能力大小的指标,用主成分分析将各单项抗旱系数综合成几个新的、相互独立的综合指标,再利用隶属函数求出综合指标的隶属值,较为准确地评价了各藤本月季品种的抗旱性。结果表明,藤本月季主要的抗旱途径为生理性抗旱,4种藤本月季品种抗旱性由强到弱为:欢腾、夏令营、西方大帝、莫扎特。评价结果为西北干旱地区特殊空间的园林绿化选择应用藤本月季品种提供了理论依据。 |
| 关 键 词： | 藤本月季 抗旱性 主成分分析 隶属函数 综合评价 |

| Abstract: | The drought resistance of four climbing rose(Rosa chinensis) cultivars was investigated by pot culture,and the physiological and biochemical indices related to drought resistance were measured under normal and water stress conditions.Taking each drought resistance coefficient as an index to measure single drought-resistance capacity,all drought resistance coefficients were synthesized into several new independent comprehensive indices by using principal component analysis.On the bases of above results,subor... |
| Keywords: | climbing rose drought resistance principal component analysis subordinate function comprehensive evaluation |
