摘　　要：为分析不同无花果的耐盐特性,为后续的耐盐品种选育研究奠定基础,以‘布兰瑞克’无花果扦插苗为试材,研究不同程度盐胁迫对植株生理指标变化趋势影响。结果表明,0.2%盐胁迫下各指标与对照组无明显差异,0.4%盐胁迫中后期开始有一定影响,而0.6%盐胁迫初期时相关指标便有极显著差异,表明该盐环境为植株能够承受的极限。在此基础上,以宿迁地区引种的‘布兰瑞克’、‘波姬红’、‘绿抗1号’、‘金傲芬’及‘美利亚’5个无花果品种扦插苗为试材,分析0.6%盐胁迫下植株生理变化,研究不同品种的耐盐特性,结果表明,不同品种无花果盐胁迫表现差异性较大,黄肉品种‘金傲芬’耐盐特性优于‘美利亚’;红肉品种‘布兰瑞克’耐盐性强于‘波姬红’,‘绿抗1号’高于‘布兰瑞克’;红肉品种耐盐性整体上强于黄肉品种。To analyze salt tolerance level of different fig cultivars, and provide foundation for salt tolerantcultivar breeding, the cutting seedlings of‘Bulanruike＇were used as materials for studying the changingtendency of physiological indexes under different salt stress levels. The results showed that the indexes of figseedlings had no significant change under the stress of 0.2% Na Cl, and certain changes were observed under0.4% Na Cl in the middle and late period, and under 0.6% Na Cl, the indexes had significant differences fromthose of the initial period, indicating that 0.6% Na Cl was the limit of salt tolerance of fig. Based on this, weanalyzed the physiological indexes＇ change of the cutting seedlings of 5 introduced fig cultivars in Suqian,namely‘Bulanruike＇,‘Bojihong＇,‘Lvkang 1＇,‘Jinaofen＇,‘Meiliya＇, under 0.6% Na Cl. The results showedthat the performance also varied considerably among different fig cultivars under salt stress, the sequence ofthe salt tolerance was‘Jinaofen＇〉‘Meiliya＇in yellow fleshed cultivars; the sequence of the salt tolerance ofred fleshed cultivars were‘Bulanruike＇〉‘Bojihong＇,‘Lvkang 1＇〉‘Bulanruike＇; and the salt tolerancelevel of red fleshed cultivars were stronger than that of the yellow.
