Abstract

Introduction: Strawberry is the fruit with the highest production among berries with a global production of over nine million tons (FAOSTAT 2017). The strawberry is one of the favorite fruits throughout the world and may be classified as a functional food as it is a rich source of phytochemicals and vitamins, both of which have relevant biological activities in human health. There is insufficient information concerning the use of Fe-EDTA in this plant. Therefore, the aim of this study was to investigate the effect of Fe-EDTA fertilizer on phenylalanine ammonia lyase enzyme activity and antioxidant properties of Strawberry fruit during developmental stages Material and Methods: The experiment was factorial based on a randomized complete block design with three replications. Experimental factor was consisted of Iron chelate (Fe-EDTA) in 0 (control) and 1400 μ mol/L levels. This experiment was carried out at Faculty of Agriculture, University of Zanjan in 2018. At the end of experiments the Strawberry fruits were harvested to measure the quality and antioxidant capacity. Finally, data analysis was done using SPSS 22 and means were compared by Duncan’ s multiple range tests at 5% level of probability. Results and Discussion: Effect of foliar application of Fe-EDTA on physicochemical characteristics of Strawberry fruits during developmental stages is presented in Table 1. Results showed that ascorbic acid and TSS were significantly increased by Fe-EDTA treatment. Also, the results showed that the Strawberry fruits treated with exogenous application of Fe-EDTA exhibited higher phenols and flavonoids accumulation in comparison to the controls. In addition, Strawberry fruits treated with Fe-EDTA exhibited higher DPPH and PAL enzyme activity concomitant with higher phenols and flavonoids accumulation. The interaction was significant in all properties. This basic iron sources is considered to be important for Strawberry fruit quality and production since they not only provide nutrients for fruit and plant growth, but also accelerate fruit ripening in strawberry plant. The experiments clearly demonstrated the beneficial effects of foliar Fe-EDTA application on quantity and quality characteristics of Strawberry fruits. These results are in agreement with those obtained by Pestana et al., (2010) and Amaliotis et al., (2002) of strawberry growth and crop yield improved by foliar application of Iron chelate. Conclusion: Generally, the findings of current study elucidated that the use of Iron chelate had strong impact on PAL enzymatic activity and quality properties of Strawberry fruits during ripening stages in this study.
