Postharvest temperature and water status influence postharvest splitting susceptibility in summer radish (Raphanus sativus L.)

Abstract

BACKGROUND: Splitting is a problem that seriously affects appearance and marketability in a number of fruit and vegetables. In summer radish (Raphanus sativus L.), splitting can occur during growth, harvesting and postharvest. We investigated the factors affecting splitting susceptibility in summer radish cv. Celesta during postharvest handling. RESULTS: Splitting susceptibility was negatively related to temperature, with higher temperature reducing splitting due to dropping impact. Radish diameter was positively associated with compression failure force, suggesting that larger radishes are more resistant to compressive splitting. An increase in radish hypocotyl water content (WC) was associated with an increase in splitting susceptibility due to impact and decrease in failure force for both compression and puncture forces. Increased hypocotyl WC may increase splitting susceptibility by increasing the water potential of the radish tissue. In agreement, we found that increased hypocotyl WC was associated with higher internal water potential in radish tissue. CONCLUSIONS: We therefore recommend that the hypocotyl WC of summer radish crops be managed during the harvest and postharvest phases, and that crops are processed at higher, ambient, temperature in order to reduce splitting, before storing at low temperature and high humidity to maintain quality and shelf life.

Meta analysis on color, total flavonoids, antioxidants, frictional, mechanical, and cutting force of moringa pods

“…As moisture migration is not uniform, peak cutting force did not show any significant trend. This implies that the mode of tissue failure observed in this work under compression and penetration is plasmolysis (Lockley et al, 2021). Similar to puncture force, the peak cutting force was doubled in the case of longitudinal direction because extra force was needed to slice the section along the diameter.…”

Role of Different Abiotic Factors in Inducing Pre-Harvest Physiological Disorders in Radish (Raphanus sativus)

“…As internal tissues expand more quickly than the periderm, putting pressure on these secondary tissues and causes them to split [48]. Factors such as external pressure, cell rupture or because of excessive tensile strength due to internal cell turgor led to hypocotyl splitting in radish [4].…”

“…As internal tissues expand more quickly than the periderm, putting pressure on these secondary tissues and causes them to split [48]. Factors such as external pressure, cell rupture or because of excessive tensile strength due to internal cell turgor led to hypocotyl splitting in radish [4]. There are many causes of radish root cracking, one of the most important is inadequate irrigation, which causes uneven growth between parenchyma cells in xylem vessels and periderm and phloem cells [3].…”

“…Radish storage roots are developed from two parts; the upper part consists of swollen hypocotyl, while the lower part is enlarged primary root tissues and lateral roots [3]. These two parts combine to form tuberous roots that are consumed raw as a salad with side dressings or cooked as vegetables [4]. Radish roots vary greatly in shape, size, color, and other external characteristics.…”

Evaluation of radish (Raphanus sativus L.) varieties under net house for off season

“…High temperatures lead to decreases in water use efficiency and net photosynthetic rate, which ultimately leads to decrease the quality and yield of a crop (Oh et al 2014). Radish splitting can occur during growth due to high temperature and moisture (Lockley et al 2020). Light intensity plays crucial role in the growth and development of storage roots in root vegetables (Cope et al 2014).…”
