The use of mycorrhizal drug Mycosoil in seed production of tomato and sweet pepper

Abstract

Research has been conducted on the effect of the Mycosoil drug on economically valuable traits of tomato of Anahit-351 and Lia varieties, as well as pepper of Hayk and Loshtak varieties. After seed treatment with the Mycosoil drug, seed germination of tomatoes increased by 1.9–2.9%, and of peppers by 4.2–4.4%. Mycosoil contributed to an increase in germination energy: for Anahit-351 tomato variety by 4.3%, and for Lia variety by 6.6%. The germination energy of Hayk and Loshtak pepper varieties increased, respectively, by 1.6–2.5%. For all tomato varieties, the yield gain varied from 9.2 to 9.6%, and for Loshtak pepper variety – 7.5 %. An increase in fruit mass was observed in tomatoes: within 20.6–23.1 g, and in peppers – 5.4–11.1 g. Both the number of seeds formed in one fruit and the mass of 1000 seeds increased. The increase in the number of seeds for tomato varieties ranged between 3.8–4.8 seeds, for pepper – 3.3–7.9 seeds per fruit, and the mass of 1000 seeds increased in the range of 0.5–0.6 g for tomato and 0.3–0.6 g for pepper. When studying the effect of Mycosoil on seedlings in tomato of Anahit and Lia varieties in the variant of Fusarium + Mycosoil, the FAM signal showed values of 20.05–25.40 and it was lower than with control + Fusarium (35.61–38.74).
