From figure 6 we can see that the errors bars don’t overlap; this means a highly significant difference exists between fractal dimension from control and treated roots. These results showed that the treatment of the corn plant with this anionic clay increases the fractal dimension of the roots. CONCLUSIONS 1. In this work we pointed out the importance of concept of fractal structure in physiological characterization of root architecture. Due the fact that the fractal dimension is a direct measure of the relative degree of complexity of the figure, we can conclude that this chemical compound influences the root architecture and this clay contributes to the increase of the root contribution to the water transport in plant and plant development. 2. We determined the planar fractal dimension (2D) of the roots, with the aid of the above mentioned photos, but for better results we must use the 3D fractal dimension and connect it with the morphological changes in root system.

INTERACTION BETWEEN CATION (NI 2+ ) AND ANIONS SULFATE AND CLORINE (SO4 2- AND Cl - ) IN THE EXPRESSION OF PEROXIDASE ACTIVITY OF SUGAR BEET DEPENDING ON THE DOSE OF NICKEL AND TEMPORARY WATER STRESS INTERACŢIUNEA DINTRE CATIONUL NICHEL (NI 2+ ) ŞI ANIONII SULFAT ŞI CLOR (SO 4 2- ŞI Cl - ) ÎN MANIFESTAREA ACTIVITĂŢII PEROXIDAZEI LA SFECLA DE ZAHĂR ÎN DEPENDENŢĂ DE DOZELE DE NICHEL ŞI STRESUL HIDRIC TEMPORAR LISNIC S. 1 , TOMA S. 1 , CORETSCAIA Iulia 1 e-mail: slisnic@rambler.ru Abstract. The excess of Ni in the environment causing significant alterations in plant growth and development, carbohydrate metabolism, increased activity of peroxidase (POD) in leaves, roots and apoplast of these organs. Lower POD activity in leaves and apoplast under Ni environmental pollution of SO4 2- anion compared to Cl - anion, especially in water culture conditions, demonstrates the interdependence of the Ni cation and anion that accompanies it on the cation in solution nutrition: increased toxicity in the form of chloride Ni compared to sulfate. POD activity in leaves, roots and apoplast of these organs is in the close interdependence of changes in plant metabolism and are crucial in the expression level of tolerance of plants to increasing doses of nickel in the environment. This interdependence is manifested both in optimal soil moisture conditions (70% WSC), and temporary water stress (35% WSC). Key words: Nickel, peroxidase, apoplast, sugar beets, water stress. Rezumat. Excesul de Ni în mediu cauzează alterări semnificative în creşterea şi dezvoltarea plantelor, în metabolismul carbohidraţilor, majorează activitatea peroxidazei (POD) în frunze, rădăcini şi în apoplastul acestor organe. Activitatea mai scăzută a POD în frunze şi apoplast la poluarea mediului cu Ni şi anionul de SO4 2- în comparaţie cu anionul de Cl - , în special în condiţiile culturii hidroponice, demonstrează de interdependenţă dintre cationul de Ni şi anionul ce-l însoţeşte pe cation în soluţia nutritivă: majorarea toxicităţii Ni sub formă de clorură de Ni în comparaţie cu sulfatul de Ni. Activitatea POD în frunze, rădăcini şi apoplastul acestor organe este în strânsă interdependenţă de modificările în metabolismul plantelor şi sunt decisive în manifestarea gradului de toleranţă a plantei la dozele crescânde de Ni în mediu. Această interdependenţă se manifestă atât în condiţii optimale de umiditate a solului (70% CTAs), cât şi de stres hidric temporar (35% CTAs). Cuvinte cheie: nichel, peroxidaza, apoplast, sfecla de zahăr, stres hidric. 1 Institute of Genetics and Plant Physiology of Academy of Sciences, Republic of Moldova 49
