Influence of weather conditions on Rubus caesius fruiting in the floodplain forests of thesteppe Pridonya

The article devoted to research of influence of weather conditions of vegetation period on yield of Rubuscaesius in the main groups of types of floodplain forests of the steppe Pridonya[1]. Relevance of research is due to the fact that, yield and quality of fruits, growth and development of Rubus depends not only on the morphology of the species, but also on weather and climatic conditions, to which it is quite demanding. In this case, the limiting factor for the growth of Rubusis winter negative temperatures. Frost damages mainly the aboveground part. The second significant adverse factor for it is considered drought, and especially prolonged, in combination with the action of high temperatures (heat), as well as dry winds [2].All this is typical for the steppe Pridonya especially in the summer period, including the Sholokhovskiydistrict of Rostov Region, where there were conducted experimental researches. The authors has studied the indicators of yield of Rubuscaesius in the dominant groups of forest types over the five-year period (2012, 2013, 2014, 2017, 2018), considered the features of weather conditions of studied vegetation periods, as well as there was studied the nature of dependence of the Rubuscaesius yield on temperature indicators and precipitation by the months of vegetation periods...
