Abstract

This study was conducted to identity the effect of plant growth retardants such as paclobutrazol, ethephon, uniconazole and daminozide by drenching on growth of Datura suaveolens 'Orange Star'. Datura suaveolens 'Orange Star' treated with the growth retardants except ethephon was gradually shortened in proportion to the treated concentration of growth retardants. Especially, uniconazole treatment dramatically short ed stem height and width of plant, diminished leaf width and length and also shortened the days to flowering, and increased flowering times per year. On the contrary, ethephon treatment showed the opposite affect such as higher plant width and plant height, increased days to flowering, and decreased the number of flower times. Dwarfing by plant growth retardants in Datura suaveolens 'Orange Star' was effective in orders of uniconazole, daminozide and paclobutrazol.

생장억제제 관주처리가 'Angel's Trumpet' 생육에 미치는 영향을 보고자 pacloblltrazol, ethephon, uniconazole 및 daminozide를 처리한 결과, ethephon을 제외하고는 생장억제제의 농도가 높아질수록 초장이 단축되었다. 특히 생장억제제 중 uniconazole 처리시 초장과 초폭이 크게 단축되었으며 엽폭과 엽장이 작아졌고 꽃수가 증가하는 경향이었으며 꽃크기 역시 단축되는 결과를 얻을 수 있었다. 또한 개회소요일수가 단축되었으며 개회횟수가 크게 증가되는 결과를 볼 수 있었다, 그러나 ethephon은 반대의 경향을 보였으며, 초장과 초폭이 커졌으며 개화일수의 증가로 개회횟수가 적어짐을 볼 수 있었다. 전체적으로 볼 때 생장억제제 관주처리에 의한 'Angel's Trumpet' 왜화의 정도는 uniconazole > daminozide > paclobutrazol순으로 나타났다.
