Influence of presowing treatment with nanocomposites upon photosynthetic apparatus of hybrid of corn

Abstract

The purpose. To study influence of newly synthesized nanocomposites (on the basis of saponite) on the content of green pigments and the square of leaf blade at plants of corn of hybrid Kharkovskii 340 MV. Methods. Laboratory, statistical. Results. It is shown that presowing treatment of seeds of corn by solutions of nanocomposites Saponite (H), Nb-Saponite (Cl), Nb-Saponite (Et) increases on the average the assimilatory surface of the square of leaf blade of plants for 20,4%. By results of spectrophotometric analysis they fixed growth of the sum of chlorophyll pigments (a + b) at plants which seeds were treated with nanocomposites Nb-Saponite (Cl) and Nb-Saponite (Et) in concentration of 300 mg/l on 41,2 and 40,6% in comparison with the control. Conclusions. It is determined that presowing treatment of seeds of hybrid of corn with nanocomposites promotes increase in the square of leaf blade and green pigments at plants.
