Abstract
RECENTLY Nickell1 reported the effect of gibberellin on several plant tissues grown in vitro. The results were generally non-specific. Sunflower petiole crowngall tissue growth was inhibited rather drastically by 10 p.p.m. of gibberellin, whereas tobacco and sweet clover were somewhat enhanced by it. Schroeder and Spector2 showed marked increased effect of gibberellin on growth of mature citron explants in the presence of indoleacetic acid, but very limited growth in its absence. The accelerating influence or interaction of indoleacetic acid on other growth factors (for example, kinetin3) and gibberellin4,5 has been a well-observed fact in many experiments and observations relating to correlation of growth factors6.
