Title: The Modified Fruit Quality by the Application of Different Kinds of Polyamines in Apricot Tree (Pronusarmeniaca)
Abstract: As polyamines are implicated in cell division, metabolism and senescence processes, they can be applied to influence fruit development process. With the aim of evaluating the polyamine induced changes in fruit qualities of apricot, Pronusarmeniaca, the current research was conducted on the basis of completely randomized block design. Apricot trees (Pronusarmeniaca) were treated with four different concentrations (0, 10, 20 and 30 mM) of various polyamines (putresin, spermin or spermidine) in ten different treatment groups. Stems were sprayed by the mentioned polyamines two times at two different flowering stages. The application of different kinds of polyamines especially spermine and spermidine resulted in the increased total soluble solid contents in fruit tissues. Putresin was the most effective treatment on fruit diameter and length in comparison to two other polyamines. The application of putresin and spermidine led to the elevated pH of fruit juice. The improved fruit firmness and fresh weight resulted from the exogenously applied polyamine treatments which reflected the alleviated senescence process. The promoted various polyamine contents in fruit tissues were observed in polyamine treated samples. The application of different used polyamines had enhancing effects on the fruit set. The obtained results from the present research indicated that the fruit quality of apricot tree affected by the applied polyamines. According to our results it could be stated that the application of various kinds of polyamines including putresin, spermin and spermidine could influence fruit set, quality and senescence which is an important factor in the related trade and industry.
