Abstract

Due to global climate warming, frequency of negative weather effects (rainfall amounts, distribution, sortness) are increasing. Rainfallamounts and frequency has also great effect of sweet cherry fruit quality around fruit ripening. Determination of optimal technologicalbasics (such as first class fruit quality and economic value) are an important task in dynamically growing sweet cherry production. This canbe solved with introduction of a new intensive training system. One of the solutions can be rain protecting foil which can reduce fruitcracking and fruit rot. Without this option sweet cherry can not be grown in many countries. In this study, fruit quality parameters werecompared from a 10 year old intensive (4 x 1m) sweet cherry orchard. The effect of rain protecting foil was tested in comparison with fruitsfrom not covered tree

Highlights

Due to global climate warming, frequency and unpredictability of negative weather effects are increasing
Rain protecting foil resulted in larger fruit size except for cultivar ’Linda’
Tendency for fruit width and height was similar to fruit size

Summary

Introduction

Due to global climate warming, frequency and unpredictability of negative weather effects are increasing This jeopardizes the most the production safety so solutions against them are extremely important task. There was an extremely large amount of rainfall in the season of 2010 (516mm, between 10 April and 26 September) In addition this rainfall occurred during fruit ripening fruit cracking and secondary fruit pathogens occurred on fruits. We can hardly count on the favorable fruit characteristics reducing the damage caused by increasing frequency of extreme weather conditions (Soltész, 2010), changing training system can be priority for the solution. This can be rain protecting for in case of sweet cherry. Competitiveness is increased if outside appearance, inner content characteristics and other quality parameters are excellent (Thurzó, 2005)
