WebNov 1, 2024 · November 1, 2024 by Yulios. Temperature and pH are two environmental factors that can affect the rate of photosynthesis. Elevated temperatures can increase the rate of photosynthesis, but too high of a temperature can actually decrease the rate. The optimal pH for photosynthesis is around 7.0, but rates can still be high outside of this … WebIncreasing the CO 2 concentration in cocoa increased photosynthesis (Pn) by 27%, which resulted in high biomass accumulation, thus improving the whole plant water use efficiency (WUE). The impact of high temperature (T max 2] could ameliorate the negative effect of high temperature and water deficit stress to certain extent. However, the ...
