Abstract

In order to provide some references for pakchoi stress resistance cultivation,by using pot experiment,the effects of exogenous ALA on plant growth and photosynthesis of pakchoi were studied under 100 mmol/L NaCl stress.The results showed that the group with 100 mmol/L NaCl+100 mg/L ALA compared with the group with 100mmol/L NaCl,increased the aboveground dry weight by 4.0%,the underground part dry weight by 15.9%,decreased the minimal fluorescence(Fo)by 11.5%,decreased the PSⅡ maximal photochemical efficiency(Fv/Fm)6.6%,the potential photochemical efficiency(Fv/Fo)36.3%,the photosynthetic rate(Pn)21.7%,the transpiration rate(Tr)15.0%,the stomatal conductance(Gs)19.3%,the total chlorophyll 14.4%.Exogenous ALA treatment might remit the effects of NaCl stress on photosynthetic rate of pakchoi.
