| 摘 要： | 研究了花期阶段不同浓度NaCl(0、10‰、20‰、30‰、40‰、50‰和60‰)对海蓬子(Salicornia bigelovii)生长、光合色素、光合作用参数、抗氧化和离子含量的影响.结果表明:10‰NaCl盐处理下海蓬子株高、茎生物量、叶绿素(Chl)含量、净光合速率(Pn)、气孔导度(Gs)、蒸腾速率(Tr)、胞间CO2浓度(Ci)、茎SOD活性和POD活性等指标值均显著高于其它处理,而高盐(40‰NaCl及其以上)胁迫下,上述指标值均表现为下降,同时茎K+含量也显著下降,而茎Na+、Cl、Na+/K+和MDA含量等显著上升.相关分析显示,生物量与Chl a/Chl b呈现显著正相关,与株高、茎Pn、Gs、Ci、Chl、Chl含量、K+含量、SOD和POD活性呈现极显著正相关,与气孔限制值(Ls)、Car/Chl、MDA含量、Cl含量和Na+/K+等均呈极显著负相关.综上所述,10‰NaCl处理是花期海蓬子生长和光合生长的最适宜盐度,而无盐和高盐下海蓬子光合抑制主要是来自气孔因素,同时高盐胁迫下还伴随着非气孔限制.
