Response of Pomegranate " Cv. Wonderful" Transplants to Mineral Nutrition and Gibberrelic Acid

Abstract

This study was aimed to investigate response of pomegranate " Cv. Wonderful" transplants to mineral nutrition and gibberellic acid, it was conducted at the Coll. of Agriculture Engineering Sciences-University of Baghdad, a factorial experiment was according to R.C.B.D. with three replicates for two consecutive growth seasons 2018-2019 to addition six treatments of nue tharyan fertilizer (N.P.K. 20:20:20 and some micronutrients) with three concentrations (0, 2.5, 5 gm.L-1) for each of the soil fertilization and foliar application, and spraying of gibberellic acid (GA3) with three concentrations (0, 50, 100 mg.L-1), and their interaction. Addition of chemical fertilizer to the soil with highest concentration (5 gm.L-1) was the most effective, where led to a significant increases in average of plant height (66.56, 47.05 cm), leaf chlorophyll content (318.3, 323.9 mg.100 g-1 fresh weight) and leaf dry weight (43.51, 50.20 %) for both seasons, respectively. The average of plant height, leaf chlorophyll content and leaf dry weight were increased when sprayed of GA3 at 100 mg.L-1 which reached (71.18, 52.99 cm), (317.5, 322.8 mg.100g-1 fresh weight) and (43.13, 48.15 %) to this traits for both seasons, respectively. the interaction between two factors showed a different effects between highest and lowest on all the traits for both seasons.

Maintenance of Pomegranate Fruit Quality by Coating With Flaxseed, Black Seed Oils, and Chitosan During Different Storage Periods

“…15 show the effect of the interactions between treatments and storage period, the significant differences were observed among them, also found that the highest value (19.52%) of anthocyanin content in fruits immersed in 1% flaxseed oil which stored for the two months, while the lowest value (9.36%) was found from fruits treated with 0.5% flaxseed oil which stored for the three months Visual evaluation (%): From the Fig. 16 the results indicated that all treatments were significantly superior to maintaining the quality of the fruits than uncoated fruits and 0.5% flaxseed oil, the fruits coated with 1% chitosan were significantly superior to the other treatments, which got the highest percentage (3.99%). While the lowest percentage was recorded in uncoated fruits.…”

“…) is an economically important crop with great nutritional value (22). Considering its importance many researchers focused on improving its productivity and quality, the pomegranate fruits are considered nonclimacteric (16,20). It is necessary to harvest fully ripened fruits; pomegranate fruits are very sensitive to storage conditions, as this causes fruit spoilage, weight loss and chilling injury (29).…”
