THE DYNAMICS OF THE PHOTOSYNTHESIS PROCESS IN SOME SWEET CHERRY CULTIVARS UNDER THE CLIMATE CONDITIONS AT RSFG IASI
The purpose of this study was to evaluate the influence of climatic conditions in the photosynthesis process at three cultivars of sweet cherry (‘Van’, ‘Andreiaș’ and ‘Margonia’) from the Research Station for Fruit Growing (RSFG) Iași. The ecophysiological response of the sweet cherry tree species was determined by evaluating the influence of light intensity on photosynthesis, as well as by determining the content of photosynthetic and carotenoid pigments of the leaves in different phenological stages (66 BBCH, 75 BBCH and 89 BBCH). The content of pigments in the leaves was analyzed spectrophotometrically, being estimated by the value of the light absorption capacity of the acetonic extract of pigments (1%) in the visible spectrum at different wavelengths. The obtained results showed that the intensity of the photosynthesis process has maximum values in the fruit ripening phenophase, the content in photosynthetic pigments (chlorophyll a and b) registering maximum values of 14.28 µg/mL, at an average light intensity of 53,000 lux.
期刊介绍：
FRUIT GROWING RESEARCH is an international journal, which has been issued under the care of the Research Institute for Fruit Growing Pitesti, Romania. Fruit growing research is an annual journal aimed at disseminating significant research and original papers on genetic resources, breeding of deciduous fruit trees species; fruit sustainable technologies – environment protection; propagation, virology and tissue culture, postharvest, that can be of interest to a wide audience of plant scientists in all areas of fruit growing. An international Editorial Board advises the journal.
