EFFICIENCY OF RESISTANCE INDUCERS IN GROWTH AND DEVELOPMENT OF TOMATOES
The problem of complex long-term stability of crops is still unresolved. In this regard, a promising and desirable is the increase of non-specific resistance of plants to adverse factors of biotic and abiotic nature by forcing the activation of natural defense mechanisms of plants by means of inductors sustainability. The inductors of resistance are compounds of biological origin or chemically synthesized compounds. It was found substances that increase the resistance of vegetative plants of tomatoes to fungal and viral pathogens. One of it is chitosan and salicylic acid. The results of their activities later transfomed into disease of treated plants, and decrease of in the extent the degree of its intensity of the spore formation of fungi pathogenic in leaves of plants treated below, activation of growth processes and morphogenetics seeds and plants, increasing the yield and quality of fruits. Bookmark and conducting experience carried out in the educational-experimental field of Kabardino-Balkarian State Agricultural University. Prototype - tomato varieties «Titan». Grade zoned in the North Caucasus region for cultivation in open field, is used as a fresh and canned, Middle-. Experience was founded on May 3. Between plants was 20-25 cm in the series, the distance between adjacent rows was 90 cm and 50 cm in one row, the calculated area of the power plant - 0,2 m2, Account area of one plot - 10 m2, all the plants on one plot - 48-50 pieces, all plots - 6. During experimental studies have been conducted to determine the effect of a certain inductor on the growth and yield of tomato plants. Research carried out by us in 2015, showed high efficacy of plant resistance inductors in growing tomatoes. Processed tomatoes inductors stability had increased vigor and germination. The highest germination was observed in the variant with salicylic acid (0,01%) and the lowest - with chitosan (0,1%) + salicylic acid (0,1%), respectively, 67,8 and 56%. Seed treatment with biologically active substances used as resistance inductors, improves yield and quality of tomato fruits. Maximum productivity is achieved by using salicylic acid without impurities, which is 35,4 t/ha.
