Özet: This research was carried out to determine the effects of different deficit irrigation strategies on phenolic compounds of Braeburn apples grafted on M9 rootstock during postharvest storage. This study involves six different irrigation treatments; none deficit irrigation, I1; continuous deficit irrigation, I2; deficit irrigation between the 40th and 70th days after full bloom, DAFB, I3; deficit irrigation between the 70th and 100th DAFB, I4; deficit irrigation between the 100th and 130th DAFB, I5; deficit irrigation between the 130th and 160th DAFB, I6. Fruits were harvested on optimum harvest time and stored at 0oC temperature and 90±5 % relative humidity for 7 months. The phenolic compounds were quantified by HPLC-DAD at harvest, 3., 5. and 7. months of cold storage. Among all treatments, epicatechin was found as main phenolic compound. Results indicate that, amount of phenolic compounds was affected by different irrigation regimes and cold storage period for Braeburn apple variety
