Abstract
A great importance in developing the photosynthesis with the trees, bushes and herbal fruit plants is represented by the presence or absence of the inflorescences on the branches, the number of leaves, the foliar surface, the number of fruit. In this article we have studied the diurnal and seasonal course of the rate of photosynthesis with the apple tree. The photosynthesis process presents variations during day, characterized by high values in the morning, followed by a decrease in the rate of photosynthesis. During springtime the values of the photosynthesis intensity are low, with a rise in intensity during summer months, after which one can notice a decrease of the photosynthesis intensity. It has been established that the rate of photosynthesis is dependent on the position of the leaf on the twig (at the base, middle or at the top), as well as on the presence or absence of fruit in the bouquet. Maximum values of the rate of photosynthesis were obtained with the leaves positioned at the middle of the twig and with the fruit-bearing bouquet.
