본 연구는 몇가지 전처리제 및 보존용액 처리가 국내 육성 절화 프리지아 ‘Gold Rich’의 수확후 절화수명과 개화 품질에 미치는 영향을 구명하고자 수행하였다. 10% sucrose, 200mg･L-1 Al2(SO4)3, 200mg･L-1 GA3, 150mg･L-1 citric acid가 혼용된 전처리 용액에서 절화 관상 기간 동안 수분 흡수량과 생체중은 유의적으로 증가한 것으로 조사되었지만 절화수명에는 큰 영향을 미치지 않았다. 보존용액으로 5% sucrose와 살균제인 300mg･L-1 8-HQ를 혼용 처리하였을 때 절화수명 연장(1일 이상), 높은 개화율(82.3~89.1%) 및 만개율(71.5~84.2%) 등의 개화 품질이 향상되었다. 이러한 결과들을 통해 10% sucrose, 200mg･L-1 Al2(SO4)3, 200mg･L-1 GA3, 150mg･L-1 citric acid를 혼합한 전처리제와 5% sucrose, 300mg･L-1 8-HQ를 혼합한 보존용액 처리는 절화수명 연장, 개화율 및 만개율 증가에 효과적일 것이라고 판단된다. 특히, sucrose가 포함된 보존용액은 절화 프리지아 ‘Gold Rich’ 의 상품성 향상에 있어 매우 유용할 것이다.

Background: Kinesiology taping (KT) is a method that helps immediately increase muscle activation, strength and joint stability by being attached to various skeletal muscles and structures of the body. Objectives: To investigate the effect of KT applied below the hyolaryngeal complex on the movement of the hyolaryngeal complex during swallowing in patients with dysphagia after stroke. Design: One-group, pre-post design. Methods: Twenty individuals with dysphagia after stroke participated in this study. KT was applied to the sternum and both clavicles from the hyolaryngeal complex. We analyzed the motion of the hyolaryngeal complex during swallowing with and placebo KT and KT using the Image-J software with videofluoroscopic swallowing study. In addition, a 0-to-10 numerical rating self-report scale was used to check the required effort and resistance felt during swallowing. Results: KT condition showed that the anterior and superior movement of the hyoid bone during swallowing was significantly lower than placebo KT (P<.05, all). Also, KT condition showed that the anterior and superior movement of the larynx during swallowing was significantly lower than placebo KT (P<.05, all). In result of statistical comparison between KT group and placebo KT group, the KT group showed significantly higher self-report scale score than the placebo KT group in terms of two category; the required effort and resistance felt (P<.05, all). Conclusion: This study demonstrated that KT applied below the hyolaryngeal complex inhibits the anterior and superior movement of hyoid bone and larynx during swallowing of patients with dysphagia after stroke.
