Вплив лазерного опромінення насіння на ростові показники та вміст хлорофілів у робінії звичайної за умов забруднення ґрунту сполуками сірки та фтору

Abstract

The result of erosion is inefficient application facilities of contamination of agriculture, technogenic emissions of industrial enterprises, pollution of car and chemicals; deflation and contamination of soils, transformates in oppression of vital functions of plants. In particular, the most dangerous thing for plants is the production of phosphates and phosphoric acid that accompanied by contamination of fluorine and sulfur. Therefore, the importance and actuality of this problem is to search new methods that increasing the plants firmness for the contamination of soil. Influence of laser irradiation on plants causes the main interest through the efficiency and unconcern. In this connection, the main aim of this research was understanding and studying the influence of preseed laser irradiation of seed, growing indexes and pigmented composition of Robinia pseudoacacia, contamination of soil by connections of fluorine and sulfur. For this seed of Robinia pseudoacacia exposed the rays as a light-emitting-diode with red laser by power of 100 milliW during 5 non-permanent or twice-permanent seconds with interval of 15 minutes. Grew pip planted in muddy soil, that according to the chart of the threefactor three-level experiment. On the thirtieth day we measured the length of escape and root, and the content of the chlorophyll a and the chlorophyll b by a. We became to the conclusion that the sulfur and fluorine connections have reliable negative influence on grew indexes and pigmented composition of Robinia pseudoacacia. We founded out that the preseed treatment of seed allows to promote the plants main grew processes of red laser rays at the terms of contamination. As a result, after laser influence the length escape increases from 10 to 100 % comparatively with the non-irradiated plants, length of root increases on 2,5-85 %. We can see, that in all variants there is increasing process of content the chlorophyll a and the chlorophyll b on 30-90 %.
