Abstract

An accumulation levels of osmolytes in chilling-tolerant and chilling-sensitive cultivar of Cucurbits against chilling stress were determined during chilling stress. Total soluble sugar contents in tolerant cultivar did not changes fur 10 days after chilling stress, but then slightly increased 20 days after chilling stress. In sensitive cultivar, it was increased rapidly in the beginning of chilling stress, and increased 3.4 times as much 20 days after chilling stress as compared with unstressed plants. Proline contents in tolerant cultivar was rapidly increased by the beginning of chilling stress, and then increased 26.6 times 20 days after chilling stress as compared with unstressed plants. In sensitive cultivar, it was increased 22.0 times 20 days after chilling stress as compared with unstressed plants. A levels of glycine betaine (GB) in tolerant cultivar increased 1.9 times as much during the 20 days of chilling stress. However, concentration of GB in sensitive cultivar did not change during the chilling stress. When plants were treated exogenous GB as a foliar spray, chilling tolerance was significantly enhanced in both cultivars. The foliar application of exogenous GB was induced chilling tolerance by accumulation of GB in the plant organs. However, it does not accumulate endogenous proline.

저온 스트레스에 대한 호박의 생육과 식물체 내 삼투조절 물질의 반응을 분석한 결과, 삼투조절물질의 축적은 저온에 대한 내성 증가에 큰 영향을 미쳤다. 가용성 당은 저온에 강한 품종보다는 저온에 약한 품종에서 축적량이 많았다. 저온 처리 시 proline은 대조구에 비해 저온에 강한 품종과 약한 품종에서 모두 증가하는 경향을 보였다. 그러나 저온에 대한 내성에 따라 축적량에는 차이가 뚜렷하였는데, 저온 처리 후 20일째의 proline축적량은 대조구에 비해 저온에 약한 품종에서는 22배 증가하였고, 저온에 강한 품종에서 는 26.6배 증가하였다. 또한 저온에 약한 품종에서는 glycine betaine이 축적되지 않았지만, 강한 품종에서는 대조구에 비해 1.9배의 증가를 보였다. Glycine betaine을 엽면 처리하면 두 품종 모두 저온에 대한 내성이 증가하였는데, 이는 체내에 glycine betaine의 축적과 밀접한 관계가 있었다.
