Influence of type of solution and storage temperature on some storage traits for two dates cultivars

Abstract EN

The experiment was conducted in one of the private orchards in the Seyahi village, Babylon province to know the Influence of type of solution and storage temperature on some storage traits for two cultivars of dates (Maktoom and Barhi).

The experiment included spraying fruits with gibberellin (GA3) solutions at a concentration of (250 mg.

L-1), licorice extract at a concentration of (4 g.

L-1) and a control treatment for both cultivars.

The fruits were then stored at the cooling temperature of 5 °C and the traditional freezing at a temperature (-18 °C) for 60 days, the experiment was implemented according to the Randomized Complete Block Design (RCBD) as a factorial experiment.

The results were analyzed using the Genastat program, The difference between the averages was compared according to the least significant difference test (L.

S.

D) at the 5% probability level.

The most important results can be summarized as follows: Maktoom cultivar was significantly excelled on the Barhi cultivar by giving it the highest percentage of total soluble solids (TSS).

While the fruits treated with gibberellin (GA3) were significantly excelled on the fruits treated with licorice by giving them the lowest average of weight loss and respiration.

The fruits treated with licorice extract have excelled by giving them the highest average of Total Soluble Solids and Pectin.

The cryopreservation method was significantly excelled in reducing the average of weight loss and the average respiration rate for fruits compared to the cryopreservation method, which has excelled by increasing the percentage of total soluble solids and lower the percentage of pectin.
