“…On the one hand, low temperatures may inhibit fungal invasion, colonization and growth, prevent the accumulation of mycotoxin in inoculated fruits, and also reduce solubility of mycotoxins. Lui and Kushalappa () also showed that warmer temperature tended to cause dry rot during initial infection, and there was a strong positive correlation between disease incidence and storage temperature in potato tubers. Similarly, Xu, Monger, Ritieni, and Nicholson () also suggested that trichothecenes production was enhanced by warm temperatures during initial infection.…”

Trichothecium roseum is one of the most dreadful postharvest pathogens responsible for core rot of apples. Besides causing economic loss, the disease is also associated with mycotoxins contamination. The effects of storage temperature and lesion diameter on T‐2 toxin and neosolaniol (NEO) accumulation were evaluated in genetically diverse apple cultivars. The results showed T‐2 concentration was much higher in Fuji than that in Ralls, while NEO was only detected in Red Delicious. The room temperature is favorable for T‐2 and NEO accumulation compared with low temperature. We also noticed the positive relationship between the size of lesion diameter and the concentrations of NEO and T‐2. NEO and T‐2 were found not only in the rotten part, but in the adjacent asymptomatic tissue, indicating that the spread of the trichothecenes to non‐infected of the fruits, and trichothecenes concentration showed a trend of decline with increase in distance from the rotten parts. Practical application Trichothecium roseum is one of the most important postharvest pathogens, and can cause core rot of apples. The disease not only causes economic loss, but also results in trichothecene contamination. Storage temperature and the size of lesion diameter significantly affected T‐2 and neosolaniol accumulation in genetically diverse apple. The results showed T‐2 toxin concentration was much higher in Fuji than that in Ralls, while neosolaniol was only detected in Red Delicious. The room temperature was favorable for T‐2 toxin and neosolaniol accumulation compared with low temperature. In addition, the positive relationship between the size of lesion diameter and the concentrations of neosolaniol and T‐2 toxin was observed. T‐2 toxin and neosolaniol were found not only in the rotten part, but also in the adjacent asymptomatic tissue, and the concentration showed a trend of decline with increase in distance from the rotten parts. The study will be useful not only for apple post‐harvest storage and reduce the health risk of exposure to the trichothecenes of T‐2 toxin and neosolaniol, but also provide baseline information for the introduction of EU‐limits for T‐2 toxin and neosolaniol.

“…ese were: Fusarium oxysporum (4 strains), F. redolens (2), F. solani (1), Gibberellapulicaris = Fusarium sambucinum (1) and Gibberella zeae = Fusarium graminearum (1). Dry rot of potato caused by Fusariumspecies is a common and commercially serious disease of potato tubers found in all production areas of the world (Nasr-Esfahani, 1998;Lui and Kushalappa, 2002;Slininger et al, 2004;Cullen et al, 2005Chehri et al 2011).

A b s t r a c tAs an organ for reserve and propagation, the tuber grows underground and is in contact with soil-borne microorganisms, making it potentially exposed to blemishes. erefore, the objective of this study was the possibility of using some modern methods of molecular diagnostics and detection of the presence of fungal contaminants in potato blemishes in Al-Qasim (Saudi Arabia). Polygonal lesions were the most observed blemish type in the collected samples. One hundred and sixty isolates were recovered from di erent types of blemishes obtained in this study. Fusarium, Penicillium, Ilyonectria, Alternaria and Rhizoctonia were the most common genera collected from different blemish types. Using ITS region sequencing, all collected fungi were identified at the species level. All Fusarium strains collected during this study were used to detect their pathogenicity against potato tubers. is is the first comprehensive report on the identification of major pathogenic fungi isolated from potato tuber blemishes in Saudi Arabia.

The potential of improving the conventional potato bulk storage process is accelerated through this thesis by defining, calibrating and validating a spatially distributed storage model that includes multiple quality aspects. The calibration and validation was performed using large-scale experimental data. Potatoes are one of the world's staple foods. While their crops are seasonal, the demand for them is continuous, resulting in the need to store them and keep them well. As the climate conditions surrounding stored potatoes influence potato quality and vice versa, climate control is an efficient way to influence product quality. Potato storage facilities therefore widely use climate control to limit losses during storage. However, good climate conditions do not automatically guarantee a high-quality end product. At present, climate control in conventional storage facilities is based on rules of thumb, gathered by trial and error and through experiments that mainly can only be evaluated once a year. Because of that, and also as a result of the increased range of potato varieties, each with its own properties, as well as of changes in growth, climate and storage conditions, finding the optimal storage climate conditions is an art and science that advances very slowly. The use of product quality control in addition to climate control was already proposed in the early 2000s, but is still not yet widely applied in commercial storage facilities due to a gap in insights into particularly the spatial distribution of how multiple quality aspects develop during storage. The aim of this research was to fill a vital gap in the knowledge on how climate and the product quality development of potatoes interact during bulk storage, by developing a spatially distributed mathematical storage model, analysing the simulation results, and evaluating these with respect to experimental data from industrial bulk storage facilities. In this thesis in particular the temperature, moisture content and reducing sugar content interaction and development in a conventional bulk storage, with a cellar and perforated floor and ventilation capacities of 100-150 cube air per cube product per hour, is evaluated and theoretically improved. A 2-D and 1-D climate-product quality model for the evaluation of the complete bulk storage process are presented in this thesis. This study particularly concerns conventional bulk storage facilities for frying potatoes, but the research is also of value for different types of storage facilities and different agro-materials.
