Тип записи:Публикация, STUDY OF THE HEAVY METALS EFFECT ON THE PIGMENT SYSTEM OF CORN VARIETIESThe degree of adaptation of plants to changes in environmental factors, new environmental conditions depends on the composition of chlorophylls and carotenoids, which are the main photoreceptors of photosynthetic cells. However, the degree of exposure of plants to the pigment complex depends on the type of plant, growth conditions, the composition and concentration of toxicants and the duration of their action. The article describes the effect of heavy metal ions on the photosynthetic pigments of 14-day-old corn varieties (Turan-170, Turan-480, Kazakhstan-435, Tauelsizdik-20), resistant and non-resistant varieties. During the experiment, we concluded that the varieties Turan-170, Turan-480, Tauelsizdik-20 are resistant, and Kazakhstan-435 are intolerant in terms of the content of carotenoids, chlorophyll-a, chlorophyll-b pigments in corn varieties (Figures 2,3,4,5). This is because Kazakhstan-435 may have varietal characteristics. In general, heavy metals have a negative effect on plants, reduce the content of chlorophyll and carotenoids, cause shifts in the structure of the membranes of chloroplasts, which negatively affects the intensity of photosynthesis. - Некоторые метрики заблокированы вашиминастройками согласия
Тип записи:Публикация, Жиделер тұқымдасы (Elaeagnаceae) жемісіндегі натрий мен калий мөлшерін атомды-абсорбциялық спектрометрия әдісімен анықтауOn this article describes method determination of sodium and potassium in fruit of medicinal plants family Elaeagnаceae by atomic absorption spectrometry. According to their content in living organisms, potassium and sodium are indispensable macronutrient, they are actively involved in metabolism, therefore these elements were identified from the species medicinal plants of the family Elaeagnаceae. As the objects of the study we collected three populations of the family Elaeagnaceae, they are Hippophae rhamnoides and Elaeagnus oxycarpa, they were collected in the Almaty region, Karasai district and Khengen district. During the experiment was performed the calibration schedule by comparing the elements of study in the fruit of family Elaeagnаceae with a standard solution. Usually prepared three comparative solutions and experimental solution, but during the reaserch work were prepared six solutions. Standard solutions of potassium and sodium (100 μg / ml) were prepared by mixing with ionized water accordıng to GSO 7474-98. In accordance with the results, a high concentration was determined from the fruits of the species Elaeagnaceae family. The World Health Organization pays great attention to drugs derived from medicinal plants. Therefore, nowadays it is important to study the healing properties of medicinal plants. From the fruits of the species belonging to the family Elaeagnаceae, as a valuable medicinal raw material for traditional and national medicine was demonstrated methods of use for various purposes and rules for collection. Key words: Elaeаgnаceae, Hippophaе rhamnoides, Elaeagnus oxycarpa, medicinal plants.
