The effect of the treatment with Nad and Ana based product on the productivity and quality of large fruit

Abstract

Ca obiect de studiu a fost luat soiul de măr Idared altoit pe portaltoiul M9, pomii au fost conduşi ca fus zvelt ameliorat, distanţa de plantare 3,5 x 0,8 m. Pentru a studia influenţa regulatorului de creştere Auxiger (NAD – 1,5 g/L + ANA – 0,6 g/L) asupra greutăţii medii, productivităţii plantaţiei de măr şi diametrului mediu a fructelor au fost montate următoarele variante: 1. Martor - fără tratare; 2. Auxiger, 0,9 l/ha; 3. Auxiger, 1,8 L/ha. S-a efectuat un singur tratament în perioada de creştere intensivă a fructelor, când diametrul lor era de 22-25 mm (09.06.2016). Cercetările au fost efectuate pe parcursul anului 2016. Cercetările, au demonstrat, că regulatorul de creştere Auxiger sporeşte greutatea medie, producţia de fructe şi diametrul mediu a lor şi poate fi inclus în sistemul tehnologic de cultivare a mărului aplicat o singură dată în doza de 1,8 L/ha când diametrul lor va fi de 22-25 mm.

The study subject of the experience was Idared apple variety grafted on M9, trees were trained as slender spindles for distance 3.5 x 0.8 m. To study influence of growth regulator Auxiger (NAD – 1.5 g/L + ANA – 0.6 g/L) on average weight of fruits, fruit production and fruit size were experimented the following variants of treatment: 1. Control – without treatment; 2. Auxiger, 0.9 L/ha; 3. Auxiger, 1.8 L/ha. Growth regulator was sprayed one time, during the period of intensive fruit growing, when the fruits diameter was 22-25 mm (09.06.16). The research was conducted during the period of 2016 year. In the present research work, we demonstrated that Auxiger increase average weight of fruits, fruit production and fruit size and may be included in the technology system for cultivation of apple, applied one spray at 1.8 L/ha when the fruits diameter was 22-25 mm.
