摘要:
在土培条件下采用模拟盐胁迫方法,研究6个辣椒(Capsicum annum L.)品种在盐胁迫下萌芽期和幼苗期的生理特性。结果表明,盐胁迫使所有供试辣椒品种萌芽期的发芽率、发芽势、发芽指数、苗长、胚根长、苗质量和胚根质量均不同程度降低;幼苗期的超氧化物歧化酶(SOD)、过氧化物酶(POD)、抗坏血酸过氧化物酶(APX)活性和可溶性糖含量总体表现为增加,过氧化氢酶(CAT)活性总体呈下降趋势,可溶性蛋白含量不同品种表现不同。方差分析发现相对发芽率、相对发芽势等14个相对性状指标均达到显著水平,基于品种因子得分值进行系统聚类分析将供试辣椒品种(系)分为3类,Y08-27和S-322尖椒为耐盐性较强的品种(系),Y148-1、Y802-1为耐盐性中等品系,Y802-2、Y08-29属于盐敏感品系。
