Abstract

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 $mg{\cdot}L^{-1}$ $GA_3$ or 200 $mg{\cdot}L^{-1}$ BA + 200 $mg{\cdot}L^{-1}$ $GA_3$ 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 $mg{\cdot}L^{-1}$ $GA_3$ or 3% sucrose + 200 $mg{\cdot}L^{-1}$ 8-hydroxyquinoline sulfate (HQS) + 100 $mg{\cdot}L^{-1}$ $GA_3$ for 16 hours extended vase life of cut stems 2.5 times as long as nontreated control. Holding solution of 2% sucrose + 200 $mg{\cdot}L^{-1}$ HQS + 100 $mg{\cdot}L^{-1}$ $GA_3$ significantly extended vase life by 3.5 times and increased fresh weight as compared with control. $GA_3$ were very effective on preventing leaf yellowing of cut Polygonatum odoratum var. pluriflorum for. variegatum stems. Postharvest foliar spray of 200 $mg{\cdot}L^{-1}$ $GA_3$ or holding solution of 2% sucrose + 200 $mg{\cdot}L^{-1}$ HQS + 100 $mg{\cdot}L^{-1}$ $GA_3$ markedly extended vase life and improved quality of cut stems of Polygonatum odoratum var. pluriflorum for. variegatum.

본 연구는 절지로 이용되고 있는 자생식물인 무늬 둥굴레 절지에 몇 가지 전처리와 후처리제인 보존용액에 의한 품질향상 및 수명연장 효과를 구명하고자 실시하였다. 수확 후 $200mg{\cdot}L^{-1}$ $GA_3$ 또는 $200mg{\cdot}L^{-1}$ BA + $200mg{\cdot}L^{-1}$ $GA_3$ 엽면살포 처리에 의해 무늬 둥굴레 절지의 수명이 현저히 연장되었다. 이 처리들은 노화되는 동안 대조구에 비해 높은 엽록소함량을 오랫동안 유지하였다. $100mg{\cdot}L^{-1}$ $GA_3$ 또는 3% sucrose + $200mg{\cdot}L^{-1}$ 8-hydroxyquinoline sulfate(HQS) + $100mg{\cdot}L^{-1}$ $GA_3$ 용액에 16시간 침지전처리는 대조구보다 2.5배 정도 수명이 연장되었다. 2% sucrose + $200mg{\cdot}L^{-1}$ HQS + $100mg{\cdot}L^{-1}$ $GA_3$ 보존용액 처리는 대조구에 비해 약 3.5배 가까이 수명이 크게 연장되었고 생체중도 증가하였다. $GA_3$는 무늬 둥굴레 절지의 잎의 황화현상을 억제시키는데 매우 효과적이었다. 결론적으로 $200mg{\cdot}L^{-1}$ $GA_3$의 엽면살포 또는 sucrose + HQS + $100mg{\cdot}L^{-1}$ $GA_3$ 보존용액 처리에서 무늬 둥굴레 절지의 수명이 크게 연장되었고 품질을 현저히 향상시켰다.
