EFFECT OF PLANTING SCHEME ON STORING OF STRAWBERRIES

Abstract

The article is devoted to the results of the study of physical quality parameters, weight loss and the production yield o f strawberries o f Polka and Pegas varieties during refrigeration storage, depending on the scheme of planting on their cultivation: banded arrangement 80+25х35 cm (control) and band with width of 90 cm. The berries are kept for eight days at a temperature of 0 ± 1°C and a relative humidity of 90-95%. It was established that the average weight o f berries grown on the scheme 80+25х35 cm to 3,3-3,6 g and 3,8-5,7 cm3 in volume surpassed the indices of grapes grown with banded arrangement. However, the density of berries grown with banded arrangement was 6,5-13,8% more than in the control.The average weight and volume of berries of Polka variety depending on planting scheme, was less than similar indices of strawberries of Pegasus variety in 1,6-1,8 times.During the first day of storing strawberries lost from 0,5 to 0,9% o f its weight, depending on the variety of plants and planting schemes. With increasing of period of life of berries the loss of mass raised gradually and in eight days it reached the level of 5,7-7,7%. Moreover, the strawberries grown on tape scheme they were higher in 0,8-1,4%, due to their higher average weight and volume and, consequently, surface evaporation. The difference in weight loss between the varieties of strawberries was not statistically significant.Product analysis of strawberries at the end of the storage period has shown that berries grown band with 3,4 and 15,0% higher yield marketable products grown on banded arrangement against the scheme. The amount of technical shortages in these embodiments experiment made 30,4-30,5% vs. 33,8-45,5% under control. Higher loss of weight that found in strawberries grown on tape scheme contributed to a significant loss of tissue turgor and fresh signs that affected the amount of technical defects. Strawberries o f Pegas variety grown with tape scheme had significantly higher yield of marketable products.
