Abstract
Wittwer, S. H., and R. R. Dedolph. (Michigan State U., E. Lansing.) Some effects of kinotin on the growth and flowering of intact green plants. Amer. Jour. Bot. 50(4): 330–336. Illus. 1963.—Dry matter accumulation of aerial parts, and heights of tomato, cucumber, and pea plants were markedly reduced when kinetin was incorporated into the culture solution root medium in concentrations ranging from 10–5 to 10–7 M. Concentrations which suppressed top growth (height, dry weight) generally had lesser effects on root growth and, in some instances, enhanced it. Thus top/root ratios were greatly reduced and approached unity in kinetin-treated peas and tomatoes. Flowering was inhibited in tomatoes and accelerated in peas. There were marked changes in root morphology, including the formation of pseudonodules. Kinetin had an effect which was opposite to that of gibberellin on internode elongation, root extension, top/root ratios and flowering of dwarf peas. N6-benzyladenine was more active than kinetin in suppressing the growth of intact green plants. The data show that kinetin can markedly alter the behavior of intact plants when absorbed by the roots from culture solutions in which the concentrations are comparable to those which are biologically active on explants.
