Effect of NaCl on growth, morphology, and camptothecin accumulation in Camptotheca acuminata seedlings

Abstract: camptothecin accumulation in Camptotheca acuminata seedlings. Can. J. Plant Sci. 83: 931-938. NaCl salt is shown to increase alkaloid accumulation in some plant species, but creates an extensive problem in plant cultivation. The effect of NaCl on Camptotheca acuminata Decaisne growth, morphology, and camptothecin accumulation (concentration and yield) was studied in a hydroponic culture system. High NaCl levels (above 75 mM) in growth media significantly reduced plant height, weight, leaf number, and leaf leng… Show more

“…Interestingly, for the 75 mM NaCl treatment, an increase in photosynthetic rate compared to the control was noticeable. This 'stimulating' effect is consistent with other reports in the literature [49][50][51].This may result from better performance of the oxygen-evolving complex (OEC) based on data that suggests beneficial interaction between Cl − and the Mn 4 O 5 Ca cluster of OEC [52]. The stimulation of plant performance under low NaCl concentrations, and inhibition under higher concentrations, is called hormesis and is well-documented in the literature [53].…”
