“…In fact, the long-term storage of fruits in the storage due to respiration, starch is hydrolyzed into glucose, as a result of this action, TSS increases and the texture of the fruit becomes softer, which softening of the texture of the fruit is caused by enzymatic activities and due to the reduction of acids as a result of fruit metabolism, the amount of acidity decreases and the pH of the fruit increases. TA shows a decreasing trend with increasing storage time 20 . Microwave treatments maintained rmness, facilitated the deastringency, and increased soluble solid contents (SSC) and sugar-acid ratio of persimmon fruit 19 .…”

“…ACording to the above results, it can be stated that with the progress of the ripening stages of the fruit in the storage and the increase in the storage time, the intensity of respiration, the production of ethylene in the fruits has increased, and this causes the breakdown of starch polymers and the process of destruction and decay of the fruit. As a result, the longer the storage period increases (especially in the fruits of growth such as mango, apricot and banana), the respiration rate of the fruit increases and this leads to the consumption of fruit nutrients and the reduction of the freshness and freshness of the fruit 6, 19,20 .…”

“…The ratio of sugar to acid is one of the important factors in determining ripeness at the time of harvest, and each of them alone shows the quality of the fruit better. The most changes that oCur when the fruit ripens are related to the breakdown of polymeric and starchy carbohydrates, especially the sugars in the cell wall, which causes a change in the fruit avor and rmness 20 .…”

Apricot fruit is of great importance due to its high quality, and the possibility of exporting it from an economic point of view. In order to maintain the quality of apricots, in addition to observing the principles of horticulture, the issue of proper storage after harvesting and managing the product until the time of sale is inevitable. In this research, the effect of microwave radiation and potassium permanganate to increase yield of apricots of the late fruiting Noori cultivar during 45 days of storage at a temperature of 2 0C and a relative humidity of 85 to 95% was studied. For this purpose, an experiment was conducted with microwave radiation (control (0)180 and 360 W), storage time (15, 30 and45 days) and 3 potassium permanganate (control − 3 and 5 g) on apricot cv. Noori. Results showed that the appearance quality and taste of the fruit improved under the influence of microwave radiation. The TSS/TA ratio increased with increasing storage time, while the application of microwave radiation and potassium permanganate decreased the fruit maturity index. The use of microwave radiation and potassium permanganate reduced the rate of fruit rot. The use of microwave radiation and potassium permanganate treatments increased the firmness of the fruit tissue. The results of this research showed that the use of microwave radiation as a type of heat treatment and potassium permanganate can be introduced as an effective strategy in the technology after harvesting apricot fruits.

“…These relationships could mean that these elements have the same sources of mineralization. The presence of these elements in the river could be due to leaching of clay minerals from the soil or agricultural land, groundwater-river exchanges, domestic wastewater discharges 42,43 and fertilizers used by irrigators in the vicinity of the river. Similarly, the high values of Mn and Ni in the river could be due to the pH of the water, the geological and pedological formation of the area, the discharge of industrial and anthropic effluents.…”

This study focused on the suitability of using an urban river for the irrigation of vegetable crops. The relevant urban river is Houet river located in the city of Bobo-Dioulasso (Burkina Faso) receives wastewater released by a wastewater treatment and purification unit (WWTP). To do this, a diagnosis of the functioning of WWTP and an assessment of the quality of the effluents released in the river were indeed carried out. The WWTP treats wastewater from industries, households and the percolating water from the treatment of the city's sewage sludge. Water released by the WWTP has a poor physico-chemical quality and high microbiological pollution. The urban river water suitability for irrigation was carried out by taking 8 water samples from the river sections at upstream and downstream parts of the WWTP junction. The physico-chemical (pH, EC, STD, Ca2+ , Mg2+ , K+ , Na+ , Cl-, HCO3- , PO43- , NO2- , NO3- , NH4+ ), microbiological (total coliform, fecal coliform, Escherichia coli and fecal Streptococci), trace metallic elements (Ni, Cr, Zn, Cu, Al, Fe and Mn) and indices such as sodium adsorption rate (SAR), percentage of soluble sodium (%Na), permeability index (PI), magnesium adsorption ratio (RAM) and Kelly ratio (RK) were analyzed and the results compared with WHO, FAO and USSL guidelines for irrigation water. The results show that the physico-chemical parameters are in line with the WHO and FAO standards for irrigation. However, the river water is reported to have medium salinity with a slight to moderate degree of restriction for EC and STD. The concentrations of ammonium (NH4+), manganese (Mn) and nickel (Ni) in the river’s water have values above standard reference for irrigation water. This suggests (i) overuse of nitrogenous fertilizers, (ii) industrial and anthropogenic discharges directly into the river, (iii) and an incomplete treatment process of water released by the WWTP. The presence of Total Coliforms, Fecal Coliforms, Escherichia coli and Fecal Streptococci at levels of around 104 to 109 CFU/100ml, above the FAO standard (2000 CFU/100ml), indicate that the river water is probably contaminated by viruses, parasites and other pathogenic bacteria of fecal origin. Houet river water is in excellent range for irrigation according to Wilcox diagram and in the C2 S1 range of medium to good quality according to the Riverside diagram. The SAR, %Na, PI, RAM and RK indices showed that the infiltration problem issue of the river water on irrigated soils is low before its junction with the WWTP and moderate after its junction. Overall, this river water is suitable for irrigation, but the presence of bacteria, ammonium and trace metallic elements require for the regional water and agricultural authorities to (i) pay particular attention to human activities in the vicinity of the river, (ii) improve the efficiency of the wastewater treatment process at the WWTP and (iii) more strictly control fertilizers’ uses by market gardeners. This will make it possible to preserve the quality of the river’ water for the irrigation of 175 hectares of market gardens products (lettuce, parsley, pepper, mint…) using a commercial urban outland to feed an urban population estimated of one million people.
