Cowpea Post-harvest Preservation & Storage
Plant Growth Regulator Application for Cowpea Yield Boost & Quality Optimization
2,4-D
Cowpeas were immersed in an 80 mg/L 2,4-D solution for 10 minutes, removed, air-dried, and then stored at (9 ± 0.5)°C. This treatment increased the endogenous hormone IAA levels in cowpeas and reduced peroxidase activity. Simultaneously, it partially inhibited the translocation of nutrients from the pods to the seeds, retarded the decline in chlorophyll content within the pods, and thereby extended the cowpeas' shelf life.
Brassinolide
Following harvest, cowpeas were immersed in a 0.48 mg/L brassinolide solution for 10 minutes and then drained. They were subsequently packaged in 0.03 mm thick PE cling film and stored in a cold room at 4°C. This treatment effectively retarded the increase in weight loss rate, relative electrical conductivity, and malondialdehyde content; inhibited the decline in soluble solids content; enhanced the activities of catalase and peroxidase; and suppressed the activities of polyphenol oxidase and lipoxygenase, demonstrating significant preservation efficacy.
