Study the efficiency of seaweed extract in improving of the storage ability of jujube fruits (Ziziphus mauritiana Lam. Cv. Tufahi)
Abstract
The present study was carried out on jujube fruits of cultivar Tufahi, planted in a commercial orchard located in the Al-Hartha district of Basrah governorate during the 2022-2023 season. Nine trees were chosen for their similarity in terms of growth strength and age, as well as their identical agricultural practices. The experiment included spraying trees with the seaweed extract 'agazone' at concentrations (0, 1, 2) mg.L‾¹ for three times. The fruits were picked when they reached maturity, and those that were undamaged and of comparable bulk were chosen and placed in bags made of perforated polyethylene (8 holes per bag, each hole 4 mm in diameter). The bag held one kilogram of fruits, which were subsequently kept for four weeks at 4°C. In comparison to the control treatment, the most significant findings demonstrated the superiority of the seaweed extract treatment, particularly the concentration of 2 mg.L‾¹, in lowering the percentage of decay and weight loss while preserving the maximum levels of organic acids and vitamin C. The results revealed that the percentage of decay as well as the fruit content of total soluble solids and total sugars rose with increasing storage duration.
