Shine

Light - an indispensable condition for the implementation of organic substances in the leaves of synthesis, ensuring a sufficient level of photosynthesis, the growth force of shoots and leaves.

In natural conditions, sunlight is the only source of energy that provides photosynthesis. In the light in the leaves of plants there is a synthesis of organic substances from the carbon dioxide of air, water and mineral substances coming from the soil. The need for lighting depends on the breed-varietal characteristics, the period of development, the phase of vegetation of plants, soil-climatic and agro-technical conditions. Most fruit crops are light-loving and, with a lack of light, grow poorly and sharply reduce the yield. But there are also more shade-tolerant breeds capable of tolerating a certain degree of shading. The highest intensity of illumination is required by reproductive organs( inflorescences, flowers and fruits).In the absence of light, they do not develop. Deviation from optimum illumination causes the crushing of leaves. Inadequate illumination, many physiological processes are destroyed( accumulation and metabolism, differentiation of tissues and cells, pollination and fertilization, the formation of fruits and seeds, etc.).With poor lighting inside the crown, the longevity of the fruit organs decreases, their productivity, the quality of the fruit. The assimilation by the plant of substances coming from the environment is directly dependent on the intensity of illumination. For better illumination, the crowns of trees and shrubs are pruned, if the planting is too tight, the plants are thinned out.

Fruit plants are photophilous and with shading reduce the yield and quality of the fruit. The abundance of light available to plants depends on the geographical latitude of the terrain, the pores of the year, the direction and steepness of the slope, the state of the atmosphere, the placement of plants, the density of the crown, etc. Good illumination inside the crown is achieved by its proper formation and pruning.

Excessive thickening of plantings can not be tolerated, since in this case plants shade each other, stretch, weaken and subsequently reduce productivity.
