Features of fruits growing of feijoa cultivars Nikitskaya Aromatnaya and Aromatnaya Fantazia

Abstract

The studies on the dynamics of the increase in fruit mass during 2015-2017 of two cultivars of feijoa of breeding of the Nikitsky Botanical Gardens: Nikitskaya Aromatnaya and Aromatnaya Fantazia. The study of fruit growth patterns makes it possible to establish optimal schedules for their growth in specific soil and climatic conditions, which affects the timing of agrotechnical measures. Three growth periods were found in feijoa cultivars: the first is rapid growth, the second is relatively slowed down, the third is the rapid increase in the mass of the fruit before ripening. The decrease in the growth rate of fetal weight occurs in the third decade of August and lasts from 10 to 30 days. It depends on the biological characteristics of the cultivar and the weather conditions of the Southern Coast of the Crimea during the formation of the fruit. Under dry conditions, feijoa slows down the processes of active growth, the culture needs additional moisture, especially it reacts to air dryness.
