Introduction. There is a growing demand in the international market forexcellent-quality dates of cultivars such as ‘Barhee’ that are consumed at the bisirstage. Materials and methods. The effects of GA3, BA and NAApostharvest dipping treatments at different concentrations on the quality characteristicsof bisir ‘Barhee’ dates during cold storage were investigated. Results anddiscussion. The total soluble solids (TSS) concentration was lower in the BA- andNAA-treated fruit than in control fruit. Similarly, the GA3-treated fruit at150 mg·L-1 contained a lower TSS concentration than control fruit. TheGA3 at 150 mg·L-1, BA at 60 mg·L-1 and NAA at (100 and150) mg·L-1 increased vitamin C concentration compared with other treatments.Acidity and total phenol concentrations were not affected by any of the treatments. Thedate soluble tannin concentration was higher than control fruit only in the dates treatedwith 20 mg BA·L-1. The weight loss % was lower in the BA-treated fruit at (20and 60) mg·L-1 compared with all other treatments, while GA3treatment at 50 mg·L-1 increased fruit weight loss % compared with controlfruit. The percentage of dates at the rutab stage (index for fruit ripening) was lower forfruit treated with GA3than for control fruit. Also, the rutab stage % was lowerfor fruit treated with BA at 40 mg·L-1 and NAA at 150 mg·L-1compared with control fruit. The TSS concentration decreased during storage from theinitial day to day 20. However, there were no further decreases in the TSS concentrationafter (40 and 60) days of storage. The acidity concentration was slightly increased duringstorage. The vitamin C concentration increased until 40 days of storage, then a slightdecrease occurred. The total phenol concentration decreased after (40 and 60) days ofstorage compared with the initial level. The soluble tannin concentration slightlyincreased at day 20 but sharply decreased after (40 and 60) days of storage compared withthe initial level. Both weight loss and rutab stage % gradually increased during storage.There were significant interaction effects between growth regulators and storage period onTSS, vitamin C concentration, weight loss and rutab stage %.
