In-vitro effects of sucrose and ascorbic acid on induction and shelf-life of micro-tuber of cassava (Manihot esculenta Crantz) genotypes

Background: Cassava production faces threat from postharvest physiological deterioration (PPD). The PPD is usually observed within the first 72 hours of harvest. Therefore, extending shelf-life cassava root-tubers by few days could reduce appreciable financial losses. Objective: This study aimed to investigate effects sucrose and ascorbic acid on induction micro-tubers cultivars using an In-vitro model. Method: Effect (30, 45, 60, 75 90 g/L) micro-tuber was determined after 45 in these (TME 1333 TME 2060). optimal level later combined with (0, 25, 50, 100 mg/L) its effect during a 10-day storage. Each laid out factorial under CRD 5 replications. Results: 30 g/L (control) produced utmost number (4.33), highest length (6.68 cm), fresh weight (0.1495 g). cultivar ‘TME 2060’ had longer (5.26 cm) higher (0.1079 g) than 1333’ 5.04 cm 0.0977 g respectively. Ascorbic (100 significantly delayed discolouration over Also, mg/L least percentage deteriorated micro-tubers. Conclusion: Results demonstrate roles formation antioxidant activity delaying PPD. we propose for In-situ (via breeding strategy) vitamin C-fortified varieties order control incidence turn improve farmer`s economy.
