Effect of Pretreatment and Holding Solution on Vase Life and Quality of Cut Polygonatum odoratum var. pluriflorum Stems

This study was conducted to examine the effect of several pretreatments and holding solutions on the vase life and quality of cut Polygonatum odoratum var. pluriflorum for. variegatum stems native to Korea. Postharvest foliar spray of 200 mg·L -1 GA3 or 200 mg·L -1 BA + 200 mg·L -1 GA3 markedly extended the vase life of cut stems of Polygonatum odoratum var. pluriflorum for. variegatum. These treatments maintained high chlorophyll contents as compared with the control (distilled water) during senescence of cut stems. Postharvest pretreatment (dipping) with 100 mg·L -1 GA3 or 3% sucrose + 200 mg·L -1 8-hydroxyquinoline sulfate (HQS) + 100 mg·L -1 GA3 for 16 hours extended vase life of cut stems 2.5 times as long as nontreated control. Holding solution of 2% sucrose + 200 mg·L -1 HQS + 100 mg·L -1 GA3 significantly extended vase life by 3.5 times and increased fresh weight as compared with control. GA3 were very effective on preventing leaf yellowing of cut Polygonatum odoratum var. pluriflorum for. variegatum stems. Postharvest foliar spray of 200 mg·L -1 GA3 or holding solution of 2% sucrose + 200 mg·L -1 HQS + 100 mg·L -1 GA3 markedly extended vase life and improved quality of cut stems of Polygonatum odoratum var. pluriflorum for. variegatum.
