Abstract

The fruiting habit pattern of white-spine cucumber, whose fruits are usually borne on the lateral branches, is different from domestic ones. The cucumber production far export has been focused on how to promote lateral shooting and how to increase the number of lateral branches. As the growing season of the exporting cucumber is confined to winter season, low temperature and weak light are limiting factors to lateral shooting. This study was conducted to investigate the effect of foliar application of growth regulator for induction of lateral shoot in white-spine cucumber. foliar application of growth regulator were focused on concentration and application time based on number of leaves. The visible damages were observed in applied leaves by $30mg{\cdot}L^{-1}$ BA(benzyladenine) in retarding culture, but no significant by $10mg{\cdot}L^{-1}$ BA in case of semi-forcing culture. The number of available lateral shoots were greater in applied plant with $10mg{\cdot}L^{-1}$ BA than that of $30mg{\cdot}L^{-1}$ BA, in applied plants at 10th and 15th loaves than that of applied plants at 5th leaves.

백침계 오이는 측지착과형으로 주지착과형인 국내용 오이와 차이가 있어 백침계 오이의 수량을 증가시키기 위해서는 측지발생을 높여야 가능하다. 그러나 백질계 오이의 재배시기는 대부분 동절기로 저온 및 일조부족 등의 불량한 환경조건 때문에 측지발생이 떨어진다. 본 연구는 생장조정제를 이용하여 백침계 오이의 측지발생을 촉진하기 위하여 BA의 농도 및 살포시기를 구명하고자 하였다 BA $30mg{\cdot}L^{-1}$을 살포한 것은 농도 장해증상이 억제작형에서는 나타났으나, 반촉성작형에서는 경미하게 나타났다. 측지발생은 BA $10mg{\cdot}L^{-1}$ 살포하는 것이 BA $30mg{\cdot}L^{-1}$ 살포하는 것 보다 많았고, 처리시기는 본엽 10매, 15매 전개되었을 메 살포한 것이 본엽 5매 전개되었을 때 살포한 것보다 많았다.
