The mechanism of action of plant growth substances: The role of nuclear RNA in growth substance action

Biochimica et Biophysica Acta (BBA) - General Subjects, 1965
Abstract Indoleacetic acid, gibberellic acid or kinetin stimulate the synthesis and release of nuclear RNA. The presence of the nuclei is essential for the growth substance-induced promotion of RNA synthesis. The induced stimulation is abolished by actinomycin D but can be restored partially or completely by relatively higher concentrations of the ...

Growth-Regulating Substances as Herbicides

Botanical Gazette, 1947
1. On the basis of the records of many experiments which demonstrated the relative toxicity of some of the growth-regulating substances and the differential sensitivity shown by plants in relation to them, the suggestion was made that greater attention be directed toward more critical study of these effects and their possible significance to ...

Growth-Inhibiting and Growth-Stimulating Substances

Botanical Gazette, 1924
When pots containing fertile soils are seeded to wheat or barley for continuous seasons, and successive short period crops of four to six weeks' growth are removed from such soils, it is found that the first crop is usually the largest, the immediately succeeding crops are much smaller, but some of the latter crops may be larger than some of the ...
