| Summary: | The effects of various growth-retarding chemicals on the growth of excised roots of Dolichos lablab in sterile culture are investigated. Application of a range of concentrations of CCC, phosfon, and B-995 inhibited growth in length of the roots by reducing the frequency of cell division, with little or no effect on cell elongation. Treated roots had generally lower DNA, RNA, and protein contents than controls, although CCC-treatment significantly enhanced the soluble nitrogen content of the roots. The inhibitory effects of growth retardants were not reversed by IAA or GA, but substances like choline chloride and pyridoxine hydrochloride were partially effective in reinstating normal growth in roots growing in concentrations of CCC producing about 50 percent inhibition of growth in length. © 1968 OXFORD UNIVERSITY PRESS. |
