- Abstract:
- Photosynthesis is an indispensable physiological activity of plant growth.There are many factors that affect the efficiency of photosynthesis.The changes of photosynthetic performance of plant leaves in acidic environment can be used to provide the theoretical basis for the application of electricity functional water，expand its scope of application.In this study，the electrolyzed water was used to sterilization the grape leaves，at the same time;it was found that the electricity function water also had the effect on the photosynthesis of the grapes.With ‘Summer black’‘Gold finger’‘Benni Fuji’‘Rosario Bianco’ 4 varieties as the object，comparison of four different processing methods:only spray acidic Electrolyzed functional water (AEW)，after spraying acidic electrolyzed water，spray basicity electrolyzed water (AEW/BEW)，spraying basicity electrolyzed water with acidic electrolyzed water (BEW/AEW)，and sprinkling tap water.The results showed that，by analyzing the physiological parameters of photosynthetic responses of grape leaves，it was found that different spraying methods had different effects on photosynthesis of grape.Among them，four grape varieties by AEW treatment，apparent quantum efficiency α and maximum net photosynthetic rate (Pmax) was significantly higher than that of other treatment groups，‘Gold Finger’ apparent quantum efficiency α was nearly 100% higher，the maximum net photosynthetic rate increased by 20%，other varieties also have 5%-10% increased，it is indicated that AEW treatment could improve the efficiency of the grape to use low light and strong light.Compared with the control group，the light saturation point (LSP) of the AEW treatment group was slightly lower than that of the control group，the value of ‘Benni Fuji’ less than 5%，while other species reduced less than 5%，which indicated that AEW could reduce the adaptability of leaves to strong light;light compensation point (LCP) was higher than that of other treatment groups，and the value was higher than 8%，and other species were higher than 5%，which indicated that AEW could improve the adaptability of leaves to low light.As for the dark respiration rate，the treatment group was slightly higher than that of the control group，the ‘Summer black’ was higher than 5%，the ‘Golden finger’ was higher than 20%，the ‘Rosario Bianco’ was higher than 25%，and the ‘Benni Fuji’ was higher than 35%.This indicated an increase in consumption.After treatment with BEW/AEW and TW，the physiological parameters were equivalent，and the physiological parameters after AEW/BEW treatment were lower than those of other treatments.It showed that AEW had not only the effect of sterilization，but also had the effect of promoting the photosynthesis of plant leaves.The other treatments could not improve the photosynthesis of plant leaves or even inhibit it by AEW/BEW treatment.The mechanism of AEW to improve the photosynthetic efficiency of plant leaves needs to be further studied.
