英文摘要	长期盐胁迫处理实验表明,随着nA Cl浓度增加,不同三角梅品种的地上部和地下部生物量均呈下降趋势。与对照相比,盐浓度为5%时,勤花三角梅生物量下降幅度最小,为27.94%;樱花三角梅下降最大,为67.03%。当盐浓度为4%时,樱花三角梅、白苞三角梅和勤花三角梅的光量子产量分别为0.36、0.30和0.36,分别为对照的78.23%、79.64%和74.82%;金心鸳鸯三角梅的光量子产量为0.05,仅为对照的15.53%。白苞三角梅的光化学猝灭系数Q P值随着盐浓度的升高无明显变化;金心鸳鸯三角梅、勤花三角梅和樱花三角梅的Q P值随着盐浓度的升高而降低。4个三角梅品种的抗盐胁迫能力为:白苞三角梅>樱花三角梅>勤花三角梅>金心鸳鸯三角梅。; The long-term Na Cl salt stress experiments showed that with the increasing of Na Cl concentration, shoot and root biomass of different Bougainvillea cultivars were decreased.At 5% Na Cl concentration, biomass of ‘Miss Manila' had the least decline of 27.94%; however, ‘Imperial Delight' had the largest decline of 67.03%, compared with the control.When the Na Cl concentration was 4%, the quantum yield of ‘Imperial Delight', ‘Shubhra' and ‘Miss Manila' were 0.36, 0.30 and 0.36, with 78.23%, 79.64% and 74.82% of the control, respectively; the quantum yield of ‘Thimma' was 0.05, only 15.53% of the control.With the increasing of Na Cl concentration, photochemical quenching coefficient q P of ‘Shubhra' had no obvious change; but q P value of ‘Thimma', ‘Miss Manila' and ‘Imperial Delight' decreased significantly.The resistance ability to Na Cl salt stress of four Bougainvillea cultivars was ‘Shubhra' > ‘Imperial Delight'> ‘Miss Manila' > ‘Thimma'.; 厦门市科学技术局项目(3502Z20124013)
