Abstract

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.

一些甜樱桃栽培品种在亚西研究中心气候条件下光合作用过程的动态变化

本研究旨在评估气候条件对雅西水果种植研究站（RSFG）甜樱桃三个栽培品种（"Van"、"Andreiaș "和 "Margonia"）光合作用过程的影响。甜樱桃树种的生态生理反应是通过评估光照强度对光合作用的影响以及测定不同物候期（66 BBCH、75 BBCH 和 89 BBCH）叶片的光合色素和类胡萝卜素含量来确定的。叶片中的色素含量是用分光光度法分析的，根据色素乙醛提取物（1%）在不同波长可见光谱下的光吸收能力值来估算。结果表明，光合作用过程的强度在果实成熟期达到最大值，光合色素（叶绿素 a 和 b）含量的最大值为 14.28 微克/毫升，平均光照强度为 53,000 勒克斯。

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.
