전처리와 보존용액이 무늬둥굴레 절지의 수명과 품질에 미치는 영향

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 ㎎ㆍl?¹ GA₃ or 200 ㎎ㆍl?¹ BA + 200 ㎎ㆍl?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 ㎎ㆍl?¹ GA₃ or 3% sucrose + 200 ㎎ㆍl?¹ 8-hydroxyquinoline sulfate (HQS) + 100 ㎎ㆍl?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 ㎎ㆍl?¹ HQS + 100 ㎎ㆍl?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 ㎎ㆍl?¹ GA₃ or holding solution of 2% sucrose + 200 ㎎ㆍl?¹ HQS + 100 ㎎ㆍl?¹ GA₃ markedly extended vase life and improved quality of cut stems of Polygonatum odoratum var. pluriflorum for. variegatum.
