“…World pomegranate production is estimated to be well above 300,000 ha [2] and an estimated 3 million metric tons annually as of 2017 [3]. In recent years, consumer demand for pomegranate has been increasing worldwide [4][5][6] due to its multiple health benefits [7,8], including strong antimicrobial and antiviral activities [9]. Research on increasing the production and supply of quality pomegranate fruit is much needed to meet consumer demand for this superfood.…”

Pomegranate, a pivotal fruit that is well recognized globally and a rapidly emerging crop in the southeastern United States and other subtropical regions, faces a formidable challenge from Colletotrichum spp., a fungal pathogen causing anthracnose fruit rot, which leads to severe to complete premature fruit drop. The development and use of disease-resistant cultivars are considered the most cost-effective and sustainable approach to managing this disease. Identifying sources of resistance is essential for developing new cultivars with improved resistance to this disease. This project aimed to expand the scope of evaluation through a 2-year field study in central Florida, examining fruit from 35 cultivars from diverse origins using both artificial inoculation at the petal dehiscent stage and natural infection. Lesion size on the fruit was measured during the growing season in a field setting. Subsequently, seven cultivars were selected for further testing by inoculating detached mature fruit and measuring lesion size to confirm observed resistance and determine the correlation between resistance observed in planta in the field and on detached fruit in the laboratory. The field study revealed significant genetic differences among pomegranate cultivars in susceptibility to naturally occurring and induced anthracnose fruit rot and classified cultivars into five resistance or susceptibility classes. Five cultivars that originated from different regions of the world, including ‘Azadi’, showed consistent resistance to anthracnose fruit rot in the field. Resistance remained strong on detached mature fruit. A strong positive correlation existed between resistance levels on in-planta fruit and on detached mature fruit, suggesting a possible simple, efficient approach to screening breeding populations for anthracnose fruit rot resistance in pomegranate. These findings represent an important step toward developing new anthracnose-resistant cultivars and understanding and improving disease resistance in this increasingly important fruit crop in the world.

Convective drying of pomegranate arils is time-consuming, energy-intensive, and affects the quality. Osmotic pre-treatment has been resorted prior to convective drying to improve drying performance and quality. In the present work, the osmosis factors such as temperature (30 - 60°C), time (50 - 250 min), and total soluble solids (TSS) (40 - 60°B) were studied using Box-Behnken design of response surface methodology. The quadratic models obtained adequately explained the process, and the optimum conditions were temperature (48.52°C), time (209.65 min), and TSS (51.31°B). The osmotic pre-treatment at optimum conditions followed by the convective tray drying reduced the drying time by nine hours, and the mean energy consumption by 0.172 MJ/g. Light microscopy revealed rupture and breakage of the honeycomb-like cellular structure of the pomegranate aril. Quality analysis of dried arils revealed that the texture (softness) and TSS improved by 11.75 N and 4.2°B, respectively. Likewise, sensorial quality parameters such as taste, mouth feel, and overall acceptability of the OATD (osmo-assisted tray-dried) arils significantly improved over the TD (tray-dried). However, there was a minor higher loss of 15.48, 12.52, and 15.88% in anthocyanin, phenols, and antioxidant capacity in OATD compared to TD. The OATD arils can be stored for up to six months in a modified atmosphere package (MAP).
