“…However, when surrounding membrane lipids are damaged by intercellular ROS, their activities are initiated in response to disruption in cellular integrity, both PPO and phenols leak from each cell organ into the cytoplasm and the enzymatic reaction is activated which leads to tissue browning [67,70]. IB sensitive radish roots showed high activity of polyphenol oxidase (PPO) and PAL (L-Phenylalanine ammonia-lyase) with reduction in glutathione reductase (GSHR) and dehydroascorbate reductase (DHAR) activities [70]. As moderately susceptible and susceptible cultivars have 1.2-3.8 times more polyphenol oxidase activity compared to resistant cultivars [32].…”

Radish, one of the important root vegetables, is widely grown in the world due to its easy cultivation, short duration, growing habit, and adaptability to various growing conditions. However, it is still extremely difficult to produce good quality radish roots due to its vulnerability to different preharvest physiological disorders. Important physiological disorders that significantly reduce the yield and quality of radish are forking, pithiness/sponginess, cracking/splitting, hollowness, and internal browning. Different abiotic factors like moisture stress, temperature fluctuation, growing medium, nutrient imbalance, plant density and harvesting time cause a disturbance in the metabolic activities of root tissues that produce non-marketable roots. Therefore, this review provides a detail insight on the causes, physiology of these disorders, and the management practices to prevent them to produce commercial quality roots. This comprehensive knowledge will not only help the growers, but it will provide relative information for researchers as well to control these disorders through breeding innovations and biotechnological tools.

Sweetpotato (Ipomoea batatas [L.] Lam) is highly adaptable to different soils and climates, but it is more sensitive to cold due to its tropical origin. Low‐temperature stress is a key factor affecting storage and has a significant impact on sweetpotato quality. During sweetpotato storage, prolonged exposure to low temperatures causes chilling damage to the root system, altering its physiological functions. This is manifested by wilting of the tuberous roots, nutrient loss, and reduced antioxidant enzyme activity. At the same time, it leads to a significant downregulation of genes associated with cold signaling pathways. Understanding the physiological and molecular mechanisms of sweetpotato's response to low‐temperature stress, which is crucial for improving its quality during storage. In addition, methods such as high‐voltage alternating electric field, controlled atmosphere, hot water treatment, and hot air treatment can better preserve the nutrients of sweetpotato and maintain their high commercial quality during low‐temperature storage. This article reviews and summarizes key studies on the nutrient and physiological changes, as well as the molecular regulatory mechanisms of sweetpotato during low‐temperature storage, and identifies unresolved questions in this field. It provides insights for further research on low‐temperature stress in sweetpotato.
