Аpplication of the interpolymer complex in growing cucumbers on Light chestnut soil

Abstract

The effect of the addition of IPC from natural polymers of chitosan and sodium alginate to the saline light
chestnut soil on the growth and development of the cucumber cultivar "Aprelskii F1" under the conditions of a
laboratory vegetation experiment was studied. A method of pre-sowing seed soaking in aqueous solutions of IPC and a
technology of two-solution treatment of the soil surface with IPC to stimulate the germination, growth and development
of cucumbers are proposed.
The bioactive effect of the use of chitosan and IPC for germination, energy, speed and amity of seed germination
in comparison with the control and sodium alginate is noted.
When assessing the effect of polymer treatment of the soil surface on the studied plants, linear growth was
measured, quantitative indicators and the leaf surface damaged by peronosporosis were calculated. The positive effect
of IPC and chitosan on the growth and development of plants was established. At the stage of flowering and fruiting,
the maximum inhibitory activity of the disease of peronosporosis of leaves and fruits was observed with the use of IPC
and chitosan. The growth-stimulating and antifungal bioactivity of chitosan and IPK can be attributed to the positive
charge of the ammonium salt of chitosan. Cationic amino groups with a higher positive charge density were more likely
to interact with the anionic components of the cell wall.
