Abstract
Eastern Europe in the past year or so has undergone unprecedented political and economic changes that took the whole world by storm. Politically, these changes signify the beginning of an end to an unpopular political system which for so long dominated that part of the world, and economically mean an easing of state monopoly and allowance for private investments and foreign capital. Foreign investors, the West not excluded, are attracted by the numerous business opportunities that now exist in these countries and the enormous potentials for economic growth. This review is based on the seminar organised by Aslib on 10.10.90, on Eastern European Business Information, and also based partly on literature review.

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 β‐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.
