The right cognition of the world distribution of citrus fruits - precise guideline for their methodical introduction - for selection.
2021
An overview of the world distribution area of citrus crops is given. There is an opinion that its correct cognition/knowledge is a good guide for the methodical selection of citrus fruits. The paper draws a red line on the idea that after the release from the rainforest phytocenosis, in the process of cultivation in open ground, in completely different climatic conditions - in different modes of moisture, soil and atmosphere, citrus fruits do not lose their natural characteristics, but as a result of natural mixing, they obtained great biological plasticity, great adaptation to low temperatures, soil and air dryness. The fact that citrus fruits have gone far in terms of adaptation to different thermal regimes is indicated by the data and the scale of their distribution. The practice of induction of citrus crops has convinced everyone that the quality of adaptation of lemons, oranges and mandarins is very high and that their promising varieties and forms can be found even further away from the place of origin, which is clearly evidenced by the humid subtropical zone of Georgia.
