the purpose of this research was to determine the effect of modified atmosphere packaging (map) containing high carbon dioxide gas concentrations on the quality of sayer dates, to be used as a safe alternative to methyl bromide fumigation. different percentages of gases (85% co2 + 3% o2 + 12% n2; 75% co2 + 12% o2 + 13% n2; 34% co2 + 37% o2 + 29% n2) were injected into the cellophane packages. t...

background and aim: cervical ripening before the onset of labor is an important factor for the prediction of delivery mode, and is directly associated with vaginal delivery. the search for a safe, inexpensive, and easy method of cervical ripening is of great significance. few studies have focused on the effect of date fruit on uterine contractions and cervical ripening. therefore, the purpose o...

This study was conducted to evaluate the effects of exogenous polyamines, isopropyl ester, 2, 4-D and naphthalene acetamide application on yield and quality of date palm of ‘Kabkab’ cultivar. The inflorescences sprayed with 2, 4-D isopropylester (0, 10, and 20 mg L-1), naphthalene acetamide (0, 80, and 120 mg L-1), putrescence and spermidine (0, 0.1, and 1.0 mM), three or six weeks after pollin...

    Different dates for apples fruit harvest (Malus domestica Borkh. Cv. Fuji) were studied to determine physiochemical changes during the storage. Fuji apples were harvested from 9 September till 23 October, at five different times and stored at 0±0.5 °C and 95% relative humidity for 120 days. To determine the best harvest date for maximum quality and storability, physical and chemical paramet...

to study the effects of planting date and planting density on quantitative traits of medicinal plant, schneider squash (cucurbita pepo l.), an experiment was conducted at research field of ferdowsi university of mashhad, in year 2012. a split plot arrangement based on randomized complete block design with three replications was used. treatments consisted of three planting date levels (1 may, 11...

The production of biobutanol was studied by the cultivation of Clostridium acetobutylicum NCIMB 13557 in P2 medium including date fruit as the sole substrate. The effect of P2 medium and the effect of different concentrations of date fruit ranging from 10 to 100 g/L on biobutanol production were investigated. Anaerobic batch culture was carried out at 35 °C incubation temperature and pH 7.0 ± 0...
