The effect of various concentrations of NaCl in the culture solution (up to 400 mM) on growth (fresh weight, dry weight, chlorophyll content) and net CO gas exchange was studied in two halophytes, Mesembryanthemum nodiflorum L. and Suaeda maritima (L.) Dum. Mesembryanthemum nodiflorum reaches optimal growth at concentrations of 100 to 200 mM NaCl in the culture medium, whereas growth of Suaeda maritima is stimulated up to concentrations of 400 mM NaCl. Independent of this stimulated plant growth, net CO uptake in the light appears to be decreased with increased salinity when net CO assimilation is calculated on a fresh weight or dry weight basis. However, expressed per mg chlorophyll, net CO uptake is clearly correlated with plant productivity at different levels of salinity.
研究了培养液中不同浓度的NaCl（高达400 mM）对两种盐生植物——松叶菊（Mesembryanthemum nodiflorum L.）和盐地碱蓬（Suaeda maritima (L.) Dum.）生长（鲜重、干重、叶绿素含量）及净CO₂气体交换的影响。松叶菊在培养基中NaCl浓度为100至200 mM时生长达到最佳状态，而盐地碱蓬在NaCl浓度高达400 mM时生长受到促进。尽管植物生长受到这种刺激，但当以鲜重或干重为基础计算净CO₂同化量时，光照下的净CO₂吸收似乎会随着盐度的增加而降低。然而，以每毫克叶绿素表示时，净CO₂吸收在不同盐度水平下与植物生产力明显相关。
