THE EFFECT OF THE “REGALIS” PREPARATION ON THE FORMATION OF ORGANS OF APPLE PLANTS AND BIOCHEMICAL PARAMETERS OF THE GALA VARIETY ON THE ROOTSTOCK P 59

abstract 1602006005 issue 160 pp. 50 – 61 30.06.2020 ru 340
The work shows the effect of the Regalis preparation on the formation and biochemical composition of organs of apple tree plants (using the Gala variety as an example). Experiments were carried out in 2016-2019. Field experiments were carried out in JSC company "Agrocomplex" named after N.I. Tkachev in the Vyselkovsky district. Planting bookmark - 2007. Tree planting scheme 4.0 × 1.0 m., Irrigation - drip. The soil of the study area is ordinary chernozem (carbonate). It was found that under the action of treatments with the Regalis preparation significant changes are recorded in the structure of fouling wood and the area of the sheet apparatus. The use of a growth regulator helps to accelerate the completion of tree growth processes. This is evidenced by a decrease in the content of IAA in the tops of shoots, by 12% in comparison with the control. The “Regalis” had a significant impact on ensuring the stable fruiting of plants of the Gala apple tree. The annual one-three-time treatment of trees with this preparation in a dose of 1.25 kg / ha provided a stable increase in yield to 14.2-16.3 kg from one tree. Moreover, on average for four years, the best results were recorded in the variant with 2-fold treatment with Regalis (16.3 kg-tree). Further analysis of the yield and commercial qualities of the obtained fruits showed that two and three-fold processing contributed to the production of fruits from 38.5 to 40.8 t / ha, which is 10-11.7 t higher than the control, while increasing the yield of marketable fruits up to 13.3 - 14.0 tons
