Abstract:
Photosynthetic characteristics were carried out with three strawberry cultivars(‘Siji’，‘Tianchali’，‘Hongyan’)In order to understand photosynthetic physiological characteristic hotosynthetic characteristics were carried out with three strawberry cultivars(‘Siji’，to provide reference for improving its yield and quality.The results showed that the individual leave net photosynthetic rate，stomatic conductance and transpiration rate had two peaks during a day，and synchronous increased or decreased.An obvious midday depression was observed.There was a significant difference in midday depression，maximum net photosynthetic rate and transpiration rate among the three cultivars.Two peaks of Pn of ‘Siji’ were higher than other two cultivars，the photosynthetic midday depression of ‘Hongyan’ lasted for a short period and the overall lower transpiration rate.Diurnal variation of intercellular CO2 concentration was negatively significantly correlated with Pn，showed that stoma was not a major regulation factor of midday depression.There was also a significant difference in different cultivars，different types of photosynthetic pigment，photosynthetic pigment content was related with photosynthetic rate，but not in a certain proportional relationship.
