Vase Life and Quality of Cut Polygonatum Odoratum var. Pluriflorum for variegatum Stem as Affected by Pretreatments and Holding Solutions

Polygonatum odoratum var. pluriflorum for. Variegatum is usually used as cut foliage for flower arrangement. However, the foliage yellowing of the stems occurs easily whe dipped in water without postharvest treatments. Postharvest foliar spray of 500 mg/L 6-benzylaminopurine (BA) or 1000 mg/L gibberellic acid (GA3) markedly extended vase life of cut stems of Polygonatum odoratum var. pluriflorum for. Variegatum. Foliage yellowing did not occur in these treatments until 30 days after treatments. Postharvest pretreatment with 3% sucrose + 200 ppm 8-hydroxyquinoline sulfate (HQS) + 250 ppm BA for 16 hours also extended vase life of cut stems three times as long as nontreated control. Holding solution of 2% sucrose + 200 ppm BA extended vase life of cut stems by more than 30 days.
