Étude des effets de l'augmentation de la température sur la croissance du pêcher et la qualité des fruits

Abstract : In the Mediterranean basin, precipitation is expected to decline as a consequence of climate change, and so will induce drought duration in summer and increase its intensity. This work focuses on characterizing the effect of the temperature increasing (in tunnels) during the early development of the fruit, of the plant growth, fruit development and its composition, to characterize the impact of heat stress on fruit quality at harvest. Our results show that trees, subjected to high temperature during the cell division of fruit, are significantly impacted about vegetative and generative growth. They accelerate their growth rate especially after being out of tunnels. This heat treatment also increased the dry matter content of the fruit. Further measurements (cells number, cell size, biochemical composition) are interesting to take into account to better understand the effects of temperature on fruit quality.
