The dynamics and diagnosis of the toxic effects of contaminated soil on the stability of seedlings wheat furious

Abstract

Ukraine is such a country where agricultural sector of industry is highly developed. Soil surface is the greatest national wealth. The life quality of the whole population depends on its condition. Agricultural soils have the highest priority in protection and utilization among other soils; and unfortunately just agricultural soils come under man-made influence to the utmost. Poltava oblast has one of the richest natural resources of Ukraine-fertile soils. It was investigated the germination and early development of vegetative organs of spring wheat that was chosen as the test plant for determination of phytotoxicity of different levels of the modulated oil contamination of soil in Poltava region. Macroscopic and morphometric experiment of structural changes in vegetative organs were conducted fourth leaf of the seedlings of wheat spring. New method of identification morphometric features of lamina by of homotopic geometrical models was offered. The usage of homotopic geometrical models feature the minimization of fault of the morphometric measuring gives the opportunity and to use the classic metrics for research of structural changes of cuts, to conduct the analysis of dynamics and determine the orientation of structural changes of biological objects in experimental terms. Investigated the dynamics of spring wheat seedlings mikromorfolohiyi depending on the content of crude oil in the soil. Found that small amounts of oil pollution (5 ml/kg) stimulate anabolic processes in the leaf blade, which is manifested in increasing their size and number of structural elements. with relatively large doses of oil contamination of soil (30 ml/kg) mass of soil significantly retards the development of structural elements of the leaf blade. The conducted researches and morphometric data gave an opportunity to discover three basic effects of influence on the germination and early development of spring wheat under conditions of the modulated oil pollution of the soil (5, 10, 20, 30, 40, 50 ml/kg). The first effect is stimulant, favorable influence of the small doses of oil (≤ 5 ml/kg) on germination and growth of spring wheat. The second effect is resistance. It is revealed in tolerance of wheat furious in action of oil contamination of soil (10-20 ml/kg). The third effect is phytotoxic. The first morphological signs of oppression of seed germination and deceleration the growth of seedlings of spring wheat in the condition of oil contamination of soil (≥ 20 ml/kg) are revealed. An increase in the concentration of oil contamination of the soil to 50 ml/kg of leads to a delay in the growth of seedlings, a decrease in the amount of chlorenchyme in the leaf plate, destruction and death of wheat furious.

Реакція Сільськогосподарських Рослин На Забруднення Ґрунту Нафтою

“…В Україні проводяться комплексні дослідження з розробки технологій використання нафтозабруднених земель для потреб сільського господарства [9,6,11]. З огляду на те, що на Полтавщині значна частина АПК знаходиться в нафтовидобувних районах, актуальним питанням залишається наукове обґрунтування екологічної оцінки агрофітоценозів, що підпадають під техногенний вплив, міграції хімічних речовин та їх наслідків у системі «ґрунт − рослина» [13,21,22], небезпечності використання зеленої маси та зерна, отриманих на нафтозабруднених ґрунтах [17].…”
