摘要:
以辣椒幼苗为材料,研究低温弱光[16 ℃/4 ℃,100 μmol/(m2·s)]和低温[16 ℃/4 ℃,300 μmol/(m2·s)] 对辣椒叶绿素含量、光合作用、叶绿素荧光参数和生理特性的影响,为辣椒冬春设施生产中的温、光、肥管理提供理论依据。结果表明,当低温弱光或低温处理时,叶片叶绿素含量、净光合速率(Pn)、蒸腾速率(Tr)、初始荧光(Fo)、最大荧光(Fm)、最大光化学效率(Fv/Fm)和光化学猝灭系数(qP)都降低,随着低温弱光和低温处理时间的延长,降低越明显,且低温弱光处理下降幅度更大;但叶片胞间CO2浓度(Ci)增大。不同处理下,叶片丙二醛(MDA)含量呈逐渐升高趋势,低温弱光处理下MDA含量高于低温处理,叶片超氧化物歧化酶(SOD)和脯氨酸(Pro)含量呈逐渐降低趋势。结果表明,低温弱光处理对辣椒造成的伤害比低温处理更为严重。
