The preservation methods as an alternative to chemical control to prevent postharvest quality losses of peppers were examined. The efficacy of harpin treatments on peppers (Capsicum annuum L. cvs. 'Demre', 'Yalova Charleston' and 'Sari Sivri') was tested in the same conditions in two different years. Peppers grown in greenhouse were applied with four treatments consisting of harpin, Botrytis cinerea, harpin+B. cinerea and control. The harpin in B. cinerea treatments reduced the percentage of rotten fruit in cv. 'Demre' from 42.68% to 22.85%, in cv. 'Yalova Charleston' from 60.87% to 26.59% and in cv. 'Sari Sivri' from 32.83% to 12.82%. The harpin and harpin+B. cinerea peppers had a better overall appearance at the end of shelf-life. Changes in percentage of red fruit and fruit color at the end of shelf life proceeded more slowly in the harpin treated fruit. The treatments of harpin gave the best results in all three cultivars. Moreover, the values obtained from fruits subjected to harpin+B. cinerea were better than those of the fruits picked from the plants only subjected to B. cinerea. In the trials, harpin slowed down the changes leading to quality loss in fruits, in all cultivars. Thus, the positive effect of harpin was revealed more clearly especially in the fruits picked from the inoculated plants.

“…Harpin protein is a natural growth regulator [Choi et al 2013]. It is used to promote plant growth and development [Akbudak et al 2007, Chen et al 2008, to stimulate plant defense mechanism [Qiao et al 2010], to improve plant resistance to pests and pathogens and to improve pre and post-harvest fruit quality [Chai et al 2004, Tubajika et al 2007. To reduce the losses throughout the storage durations, post-harvest Harpin treatments were used in apples [De Capdeville et al 2003], pears [Wang et al 2011], melons [Bi et al 2005], oranges [Lucon et al 2010] and grapevines [Tubajika et al 2007].…”

This study was conducted to investigate the effects of pre-harvest Harpin treatments and post-harvest MAP treatments on fruit quality attributes and bioactive compounds of '0900 Ziraat' cherry cultivar throughout cold storage and shelf life of the fruits. Weight loss and decay ratios were significantly reduced with Harpin and MAP treatments. In general, lower L* and chroma values were measured in Harpin-treated fruits. As compared to control fruits, higher firmness, titratable acidity and vitamin C contents were measured in MAP and Harpin + MAP treated fruits throughout the cold storage and shelf life. On the other hand, lower solible solids content (SSC) values were observed in the same treatments. At harvest and shelf life measurements, higher total monomeric anthocyanin (TMA) and total phenolics (TPs) were measured in Harpintreated fruits than in control fruits. Although lower anthocyanin contents were obtained from MAP-treated fruits throughout the cold storage, higher values were observed throughout shelf life. Throughout cold storage and shelf life, MAP-treated fruits had lower total phenolics and total antioxidant activity (according to FRAP and TEAC assay) values than the control and Harpin-treated fruits. It was concluded that Harpin and MAP treatments could be used reduce weight losses and decays throughout the cold storage.
