Abstract

Photosynthetic rate (Pn) and the partitioning of noncyclic photosynthetic electron transport to photorespiration (JO) in seedlings of four subtropical woody plants growing at three light intensities were studied in the summer time by measurements of chlorophyll fluorescence and CO2 exchange. ExceptSchima superba, an upper canopy tree species, the tree speciesCastanopsis fissa and two understory shrubsPsychotria rubra, Ardisia quinquegona had the highestP n at 36% of sunlight intensity. The total photosynthetic electron transport rate (JF) and the ratio ofJ O/JF were elevated in leaves under full sunlight.J O/JF ratio reached 0.5–0.6 and coincided with the increasing of oxygenation rate of Rubisco (VO), the activity of glycolate oxidase and photorespiration rate at full sunlight. It is suggested that an increasing partitioning proportion of photosynthetic electron transport to photorespiration might be one of the protective regulation mechanisms in forest plant under strong summer light and high temperature conditions.
