Effects of Drought on Pome Fruit Species

Abstract

Apple, pear, quince, persimmon, loquat, medlar and hawthorn are among the pome fruit species with significant production potential in the world. Temperature is the most important climatic factor which can lead to limiting the cultivation. The increase in drought with global climate change and the difficulty in accessing water resources are emerging as the most important effects of temperature in recent years. With the effect of morphological, biochemical, physiological and molecular changes in pome fruit species under water stress, it leads to a decrease in quality parameters, yield and negatively affecting the economic yield value of pome fruit trees. Resistance breeding, kaolin, melatonin, anti-transpirant (brasinolide), stem reduction, silica, nitric oxide, nutrient application, inoculation with mycorrhizal fungi and plant growth-promoting rhizobacteria, soil tillage practices and shade cover systems are different methods and applications that are widely used in order to reduce the negative effects of water stress on pome fruit trees. In this study, the effects of drought on some pome fruit species were tried to be revealed.
