The responsiveness of the table grape varieties Vostorg (with bisexual flower) and Talisman (with functionally female flower) to growth regulators has been studied using gibberellin, Mycephyt, Zircon, Epin-extra and their mixtures. Terms of treatment: before flowering, during mass flowering, at the end of flowering and during the period of berry growth. The following parameters were evaluated: the mass of the bunch, berries and stem; the number of well-developed and shot berries in the bunch; the yield and sugar content of the berries. The highest yield increases constituted 9,3 t/ha for Talisman variety (Mycephyt, 10 mg/l) and 7,9 t/ha for Vostorg variety (Mycephyt, 100 mg/l). The positive effect was achieved at the expense of the higher bunch mass, higher number of berries in the bunch and higher berry size. The highest bunch mass (563,2 g) was obtained with Vostorg variety using the mixture Mycephyt (10 mg/l + Zircon (0,4 ml/l + Epin-extra (0,1 ml/l). An increase in the number of both well developed and shot berries was noted in the majority of variants. The exception were three variants (Vostorg) using: 1) gibberellin (100 mg/l), 2) Mycephyt (100 mg/l) and 3) the mixture Mycephyt (10 mg/l) + Zircon (0,4 ml/l). In these cases there was an increase in the number of well developed berries while the number of shot berries was reduced. In two variants (Talisman) using Epin-extra (0,1 ml/l) and the mixture Mycephyt (10 ml/l + Zircon (0,4 ml/l), a negative effect was noted on the formation of well developed berries, their number being distinctly lower than in the control (water spraying). The growth regulators exerted a stimulatory effect on the mass concentration of sugars in berry juice. |
