| heal.abstract | Diurnal and seasonal fluctuations in water potential (T), stomatal conductance (g(s)), transpiration rate (E), and net photosynthetic rate (P-N) were monitored in Capparis spinosa L., a Mediterranean plant growing during summer, i.e. at the period considered the most stressful for local plant life. In spite of the complete absence of rain, T exhibited a modest drop at midday (-2.7 MPa), but was fully recovered overnight, indicating sufficient access to water sources. The stomata remained open throughout the day and season and the high E resulted in leaf temperatures up to 3.9 degreesC below air temperature. Additionally, P-N of the fully exposed leaves was higher than 25 mol m(-2) s(-1) for more than 10 h per day throughout the summer growth period. No symptoms of photooxidative stress were shown, as judged by maximum photosystem 2 photochemical efficiency (F-v/F-m) and the function of xanthophyll cycle. Indeed, diurnal inter-conversions of the xanthophyll cycle components were modest during the summer and a more intensive function of the cycle was only evident during leaf senescence in autumn. In comparison with a semi-deciduous and an evergreen sclerophyll co-existing in the same ecosystem, C spinosa assimilated up to 3.4 times more CO2 per in 2 during its growth period (May to October) and up to 1.8 times more on an annual basis. | en |
