摘要:
为探究纳米硒和红蓝光配比对生菜生长和光合特性的影响,以意大利耐抽薹生菜为试材,采用水培法,在红蓝光比例为4∶1、1∶2及单独红光与蓝光照射条件下,分别用不同浓度(0、24、48 μmol /L)纳米硒溶液对生菜叶面进行喷施处理。结果表明:(1)在4∶1红蓝光、1∶2红蓝光及红光照射条件下,喷施纳米硒均能有效提高生菜生物量,其中在4∶1红蓝光照射下喷施48 μmol/L硒溶液时,植株生物量最高且增幅最大。(2)增加蓝光比例可提高叶片叶绿素含量,且在单独蓝光照射下喷施48 μmol/L硒溶液时,叶绿素含量最高且增幅最大。(3)纳米硒在4∶1红蓝光下可提高叶片净光合速率与蒸腾速率,并降低其水分利用率,在单独红光照射下增大了气孔导度,在单独蓝光照射下可提高水分利用率,并降低其胞间CO2浓度、蒸腾速率与气孔导度。综上,在4∶1红蓝光照射下喷施48 μmol/L硒溶液对生菜光合作用和生物量积累的促进效果最好。
