Influence of the biological characteristics of the variety on the productivity of the plantation and the quality of the apricot fruits during the fruiting period

Abstract

The researches were carried out in the spring of 2015 from the company "Agroparc Management" SRL, located in the southern part of the country. As biological research material, trees from apricot varieties were used: Wonder Cot, Magic Cot, Spring Blush, Lilly Cot, Perle Cot, Pinkcot, Sweet Cot, Orange Red, Big Red, Faralia, Kioto and Farbaly. The Orange Red variety was taken as a control. The varieties were grafted onto Mirobalan 29C rootstock. The trees formed by open vase crown type. Planting distance 5.0 x 3.0 m. The lot is not irrigated. The soil between the intervals, between the rows and between the trees in the row was maintained as black field. The atmospheric precipitation that fell in abundance in the months of April (73.6 mm) and May (46.0 mm) in the southern part of the country had a considerable impact on the quality of the fruits of the early ripening apricot varieties (Wonder Cot, Spring Blush, Magic Cot, Pinkcot). Medium and late ripening cultivars had slower fruit development due to insufficient moisture during the development period.
