Abstract:

Purpose – The aim of this research is to determine the effects of pre-harvest harpin (H) and modified atmosphere packaging (MAP) on the storage and fruit quality of cherry tomato (Lycopersicon esculentum Mill. cvs. “Alona” and “Cluster”).

Design/methodology/approach – H was used at 50?g 100 l-1 concentration. First application was done on the seedlings in 3-4 leaf stages and the other four applications were repeated at 20-day intervals. Then, treated and untreated fruits were stored in plastic film materials with various O2 and CO2 permeabilities.

Findings – Weight loss was significantly higher in tomatoes stored under normal atmosphere (NA) compared to MAP. Initial total soluble solids of 3-4 percent increased to 7-9 percent in without H (WH)+NA. Firmness was measured as 0.44 (“Alona”) and 1.20?kg (“Cluster”) in H+NA and 0.17 (“Alona”) and 0.30?kg (“Cluster”) in WH+NA at the end of storage. The acidity and ascorbic acid contents of tomatoes decreased during storage. Between H and WH treatments the levels of lycopene and ß-carotene were different significantly. At the end of the study, H gave successful results in both cultivars. This success was even higher especially when the H was combined with MAP. This combination slowed down the changes in TSS, firmness values. Therefore, H+50µ PE (polyethylene) treatment was effective with regard to delaying the maturity along the storage and fruit quality in cherry tomatoes.

Originality/value – He is a plant activator. It is the first bacterial hypersensitive response (HR)-elicitor characterized. Effectiveness of H is evaluated on quality changes in treated cherry tomato fruits.
