Cyclohexylamine과 Polyamine이 대두 자엽의 부정근 형성에 미치는 영향

In order to study the effect of cyclohexylamine(CHA) and polyamines during adventitious root formation, the correlation of adventitious root formation with endogenous polyamine content was investigated in inoculated soybean cotyledons at the rooting medium supplemented with CHA, spermidine and spermine. Adventitious root formation was inhibited in medium containing 1O??-10??M CHA. Adventitious root formation was not formed in treatment with 1O-2M CHA plus polyamine. It was inhibited in 2.5×lO??M CHA alone and reversed in 2.5×1O??M CHA plus 10??M spermine. Putrescine content was lower in 10??M CHA and 1O??M CHA plus 10??M spermine treatment than in control after 3 days of incubation. However, it was higher in 2.5×lO??M CHA and 2.5 × lO??M CHA plus 10??M spermine treatment than in control. Spermine content was higher in all CHA treatments than in control, while spermidine content was lower than in control.
