Photochemistry and Antioxidative Capacity of Female and Male Taxus baccata L. Acclimated to Different Nutritional Environments.

ABSTRACT: In dioecious woody plants, females often make a greater reproductive effort than male individuals at the cost of lower growth rate. We hypothesized that a greater reproductive effort of female compared with male Taxus baccata individuals would be associated with lower female photochemical capacity and higher activity of antioxidant enzymes. Differences between the genders would change seasonally and would be more remarkable under nutrient deficiency. Electron transport rate (ETR_max), saturation photosynthetic photon flux corresponding to maximum electron transport rate (PPF_sat), quantum yield of PSII photochemistry at PPF_sat (Φ_PPFsat), and chlorophyll a fluorescence and activity of antioxidant enzymes were determined in needles of <
