ABSTRACT
            Trees of pome fruits (apple, pear and quince) and stone fruits (apricot, peach, plum, and cherry) grown under warm winter areas  face some problems causing low or limited fruit production. Such problems are: late leaf defoliation, insufficient chilling requirements, bad cultural practices, misusing of breaking dormancy agents and self incompatibility in some cultivars.   Such problems and their solutions will be discussed. The following solution will be reviewed and clarified: Breaking seed dormancy of deciduous rootstocks, select suitable low chilling requirement cultivars, applications of leaf  defoliation agents, suitable cultural practices (Correct training and pruning – Suitable Irrigation system) and recommended timing and concentrations of dormancy breaking agents.
