Abstract

fetched live from OpenAlex

In the present study,the response characteristics of gas exchange parameters for the diurnal variation of the mulberry leaf to simulated acid rain with different p H have been studied to reveal the mechanism and the effects of simulated acid rain on plant photosynthetic productivity. The results showed that net photosynthesis rate( Pn)present obviously photosynthetic depression at midday in treatment of CK( no acid rain),while three treatments of simulated acid rain could increase Pnat midday. During photosynthetic noon-break,stomatal conductance( Gs)and stomatal limitation value( Ls) decreased,but the intercellular CO2concentration( Ci) increased,the results of correlation analysis showed that Pnand Ciwas significantly negative correlation,which indicated that CO2 assimilation have been inhibited. The corresponding parameters under acid rain treatments showed similar change trends with CK excepted with that the Ciwas lower than that of CK,and Gswas higher than CK,indicating that the simulated acid rain treatments could promote stomatal opening and CO2 assimilation of mulberry leaf during midday depression. Atmospheric temperature( T) significantly positively correlated with leaf saturation water vapor pressure deficit( Vpdl) and transpiration rate( Tr),respectively. However,there was significant negative correlation between T and atmospheric relative humidity( RH). Meanwhile,the value of RH was near the minimum value during midday depression of photosynthesis,which indicated that CO2 assimilation inhibition most come from water shortage. While Tr,Gsand Lsin treatments of simulated acid rain with p H≥4. 5 were higher than that of CK,and the water use efficiency( WUE) in simulated acid rain had no significant difference with CK which indicated that simulated acid rain could promote mulberry leaf intercellular water supplying. In treatments of simulated acid rain with p H 3. 5,the photosynthetic assimilation total( PT),average Pnand Gswere significantly lower than that of CK,while the corresponding parameters of p H 5. 6 and p H 4. 5 were higher than that of CK. These results suggested that treatments of simulated acid rain with p H≥4. 5 had significant promoting effects on the photosynthesis of mulberry.In the region with mild acid rain pollution,the mulberry could be employed as plants for returning farmland to forest and landscape to absorb atmospheric SO2 and nitrogen oxides and adapt or lighten the atmosphere of acid rain pollution.

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.
