e0“ALA played a positive role in alleviating the effect of suboptimal temperature and light intensity on photosynthesis of cucumber seedlings”
e1“suboptimal temperature and light intensity decreased the net photosynthetic rate(Pn),stomatal conductance(Gs),carboxylation efficiency(CE),apparent quantum yield(AQY),actual photochemical efficiency of PSⅡ(ΦPSⅡ),photochemical quenching(qP),antenna transformation efficiency(Fv'/Fm'),and activities of RuBPCase and FDPase of cucumber seedlings,but increased the intercellular CO2 concentration(Ci)”
e2“compared with the normal temperature and light intensity,suboptimal temperature and light intensity led to significant decrease in the light compensation point(LCP)and CO2 compensation point(CCP)”
