“…In the storage at room and cooling temperatures, a decrease in the acidity index after six months of evaluation was observed, regardless of the drying temperature. The results of this study are in agreement with previous studies where in undamaged grains stored at room temperature and moisture below 12%, small variations in acidity levels occurred 26 , 62 .…”

Drying and storage methods are fundamental for maintaining the grain quality until processing. Therefore, the aim of this study was to evaluate the associations of the drying temperature with storage systems and conditions as a strategy for preserving the quality of maize grain postharvest on laboratory and field scales. An increase in temperature accelerated the reduction in grain moisture, but increased the deterioration. The wetting during the storage period reduced the grain quality. Hermetic and aerated storage systems maintained the chemical quality of the grains. The control with healthy and whole corn dried at 80 °C and stored in silos with natural aeration provided a satisfactory quality, equivalent to those of controlled drying and storage under airtight conditions and at low temperatures. Different conditions of drying and storage of corn on the laboratory and field scales were evaluated, which provides an appropriate management of these operations to maintain the grain quality.

“…Hamid and Jawaid (2011) reported that pretreatments with UV-A and UV-C radiations stimulated the germination and growth of Mung bean through auxin biosynthesis. It has already been known that UV-C radiation improves the seed quality and germination in crop seeds prior to sowing, owing to its antifungal capacity (Ferreira et al 2018). On the other hand, our results were in line with the study of Rahimzadeh et al (2011) who revealed that the growth inhibition effect of UV-C was much more severe than that of UV-A in Satureja hortensis seedlings.…”

Living organisms are increasingly exposed to ultraviolet (UV) rays of solar radiation, both due to the thinning of the ozone layer and the widespread uses in sterilization processes. The present study was conducted with the purpose of evaluating the damages of UV-A and UV-C radiations in Allium cepa L. roots. Three groups were formed from Allium bulbs, one of which was the control group. One of the other groups was exposed to 254 nm (UV-C) and the other to 365 nm (UV-A) UV. Growth retardation effect of UV was investigated with respect to germination percentage, total weight gain and root elongation, while genotoxicity arisen from UV exposure analyzed using mitotic index (MI) and chromosomal aberrations (CAs) including micronucleus (MN) frequency. Oxidative stress due to UV application was investigated based on the accumulation of malondialdehyde (MDA) and the total activities of superoxide dismutase (SOD) and catalase (CAT) enzymes. Also, meristematic integrity of the UV treated roots was controlled. UV treatments caused significant changes in all parameters compared to the control, but all effects were much more prominent in 254 nm UV-exposed group. This study clearly revealed that UV exposure triggered growth inhibition, genotoxicity, oxidative stress and meristematic cell damages in A. cepa roots depending on the wavelength.

We quantitatively evaluate the effects of UV-C radiation on bean seeds Oti (Phaseolus vulgaris), their germination and phenolic compounds of seedlings, by means of photoacoustic spectroscopy and scanning electron microscopy. It is shown that: i) The photoacoustic signal produced by the bean seeds exposed to UV-C radiation during 15 minutes, reduces from 0.24 to 0.10 mV for the wavelengths of 295 and 340 nm, as a result of their degradation. This significant reduction of 58.3% decreases, but keeps over 50% for other spectral UV wavelengths within the interval (270-400 nm). ii) As the UV-C radiation time increases from 2 to 15 min, the morphological changes at the surface of the bean seeds exhibits micro-holes and detachment of the cotyledon sclereids. iii) There are no significant statistical differences in the variables of germination, dry weight and seedling length, for exposure times up to 15 minutes. iv). The phenolic acids and flavonoids of the bean seedlings of seeds treated by UV-C for different exposure times (0, 2, 5, 10 and 15 min) display significant statistical differences (P ≤ 0.05) in both roots and foliage. For both the roots and foliage, the highest concentration of phenolic acids is observed at 10 and 15 minutes, while for root flavonoids, it appears at 5 and 15 minutes.
