Opis:: Effects of 24-epibrassinolide (EBR) treatments on chlorophyll (Chl) degradation and postharvest quality of two lime (‘Persian lime’ and ‘Tahiti’) cultivars during chilling-induced storage were studied in this work. EBR at 0, 2.5, 5 and 10 µM were applied to fruit by vacuum inﬁltration at 30.63 kPa for 7 min and afterward stored at 4°C for 60 days. Postharvest EBR application effectively maintained greater fruit ﬁrmness and lessened weight loss during cold storage. The results displayed that EBR treatments efﬁciently delayed the reduction of the Chl a contents and hue values. EBR treatments significantly increased ascorbic acid content, total phenolic content (TPC), antioxidant activity, and titratable acidity (TA). On the other hand, the treatments reduced soluble solids concentration (SSC), pH, and SSC/TA ratios during cold storage. Overall, EBR application by vacuum infiltration could be an effective and simple method for maintaining postharvest quality of limes during cold storage.

Opis:: During the cold storage of sweet cherry, severe losses can occur due to the water loss, phytopathogenic fungi and physiological disorders. The aim of this research was to assess the effects of treatments with NAA (α-naphthaleneacetic acid), BA (6-benzyladenine), and GA3 (gibberellic acid) on fruit quality at harvest and after 21 days of storage under two regimes, including 0°C, RH (relative humidity) 90% and 3°C, RH 70%, and after additional shelf life exposure. Sweet cherry cultivars – ‘Summit’, ‘Kordia’ and ‘Regina’ – were treated with bioregulators at the end of flowering. NAA significantly increased the fruit weight at harvest compared to the control in all cultivars assessed. BA stimulated the fruit growth in ‘Kordia’ and ‘Regina’, while it was ineffective in ‘Summit’. GA3 caused significant increase in fruit weight by 8.3% in ‘Kordia’ only. Moreover, BA and GA3 induced a higher firmness of fruits at harvest. Weight loss of fruits during storage at 0°C, RH 90%, was increased with NAA and reduced with GA3 in ‘Regina’ only. BA and GA3 reduced the weight loss of sweet cherry fruits stored at 3°C, RH 70%. Bioregulator treatments increased TA (titratable acidity) in fruits at harvest, while the effects on TA during storage were variable depending on the cultivar. ‘Summit’ had the highest sensitivity to storage fruit rot. BA and GA3 decreased the disease occurrence on fruits stored at 0°C in ‘Summit’ and ‘Kordia’.

Opis:: Black mold and green mold caused by Alternaria alternata and Penicillium digitatum, re- spectively, are the most important decay pathogens of tomato fruits during storage. Our research was aimed to control tomato phytopathogenic fungi A. alternata and P. digitatum in vitro and in vivo by using natural nanomaterials rosmarinic acid (RA-NPs) at concentra- tions of 0.3 and 0.6 mM, glycyrrhizic acid (GA-NPs) and glycyrrhizic acid ammounium salt (GAS-NPs) (0.1–0.2 mM). Characterizations of the tested nanoparticles were carried out by using dynamic light scattering which revealed that synthesized nanoparticles had particle sizes of less than 100 nm. In vitro studies revealed that the three tested nanopar- ticles reduced the growth of A. alternata and P. digitatum. Glycyrrhizic acid nanoparticles were the most effective in reducing the growth of the two tested pathogens followed by RA-NPs at 0.6 mM. Observations of A. alternata and P. digitatum by scanning electron microscopy (SEM) showed severe damage in the hyphae and deformities in the conidia due to the effect of the tested nanoparticles. In vivo results showed that, dipping tomato fruits as a post-harvest treatment in all of the tested nanoparticles at different concentrations, then stored at 10 ± 1°C and 90–95% relative humidity (RH) for 20 days greatly reduced the disease severity of infected fruits with the two tested pathogens. GA-NPs at 0.2 mM signifi- cantly reduced the development of black mold rot on tomato fruits. RA-NPs at 0.6 mM had the best effect in controlling P. digitatum of all naturally and artificially inoculated tomato fruits. Also, individual treatments of tomato fruits with RA-NPs, GA-NPs and GAS-NPs significantly reduced postharvest losses of fruit since they delayed decay and maintained fruit quality characteristics such as fruit firmness, titratable acidity and total soluble solids during cold storage.

Opis:: Blackberries (Rubus spp.) have significant nutraceutical properties, providing phenolic compounds for the consumers. These compounds are useful to human health due to their high antioxidant activity. However, most blackberries destined for fresh markets become unmarketable in 2 to 3 days due to decay and leakage, because they have thin and fragile skin. The present study was aimed to investigate the effect of salicylic acid (SA) and calcium chloride (CaCl2) on extending the postharvest quality and bioactive compounds of blackberry during refrigerated storage. Blackberry fruits cv. ‘Jumbo’ were dipped in 2% CaCl2, or in 2.0 mM salicylic acid (SA) for 10 min. Total soluble solids contents, titratable acidity, pH, ascorbic acid contents, total phenolics contents, and total antioxidant activity were investigated initially on 4th, 7th, or 10th day (d) of storage. Changes in fresh weight, titratable acidity, ascorbic acid and total phenol contents were markedly delayed by both treatments. Berries treated with 2 mM SA or 2% CaCl2 exhibited markedly better visual quality during the storage period. Considering the overall findings, this study revealed that postharvest SA or CaCl2 applications maintained the storage-life and conserved the valuable marketing features of blackberries over 10 d in cold storage, presumably due to their inhibitory effects on fruit senescence.

Opis:: The interaction between foliar treatment with 100 mg∙dm–3 of both gibberellic acid 4+7 (GA4+7) and benzyladenine (BA) and vase solution containing 3% sucrose was analysed in cut Lilium ‘Alma Ata’. GA4+7+BA considerably delayed leaf senescence, suppressed anthocyanin accumulation in the leaves of plants held in the sucrose solution and improved the average longevity of the flowers and the vase life of the stems. Sucrose in the vase solution strongly reduced the abscission of leaves and contributed to the enlargement of the top flower. The number of significant interactions between the treatments indicated that the investigated factors acted dependently mainly on flower quality, while their action on leaf quality was mostly independent. Results show that combined treatment with growth regulators and sucrose may considerably increase postharvest quality of cut Lilium ‘Alma Ata’.

Opis:: This study was done using three nitrogenous compounds to evaluate their effects on postharvest characteristics of chrysanthemum (Chrysanthemum indicum) cut flowers. The study consisted of three separate and parallel experiments, in which ammonium sulfate, calcium nitrate and potassium nitrate were used in different concentrations of zero, 50, 100, 200 and 500 mg dm ‒3 N for pretreatment of stems for 6 hour before transferring to holding d-water solution. The results showed that petal ion leakage and leaf SPAD values were increased by increasing ammonium sulfate, but not calcium or potassium nitrate. Petal carotenoids were increased by pretreatment of ammonium sulfate and potassium nitrate. There was constant increase in water uptake by increasing the levels of calcium nitrate and potassium nitrate, while ammonium sulfate at high concentrations (200 and 500 mg dm ‒3 N) resulted in significant less water uptake compared to control. Ammonium sulfate in 50 and 100 mg dm ‒3 increased shelf life of pretreated stems, but higher concentrations significantly reduced cut flowers shelf life. Increasing concentrations of calcium nitrate and particularly potassium nitrate have led to prolongation of flower shelf life to 12 days compared to 6 days of control. The results indicate that pretreatment of chrysanthemum cut flowers with ammonium sulfate in rather low concentrations or with moderate to high concentrations of calcium nitrate or potassium nitrate can significantly improve shelf life and postharvest flower qualities.
