Synthetic Growth

The preparation and biological examination of a number of arylcarbamic esters (arylurethanes) are described. The experiments demonstrate the marked effect of iso propyl phenylcarbamate and some related compounds in very low concentrations upon the germination and seedling growth of cereals. The absence of effect of the same compounds in similar concentrations upon some dicotyledonous plants is noted.

Species Being

Apices of plantlets obtained through germination and portions of maple stems with at least one node were grown under aseptic conditions in tubes with agar-eontaining synthetic medium. Trials were made on media with or without growth substances. For three species (Acer negundo, Acer pseudoplatanus, and Acer saccharum) the development of aerial parts and rooting of explants were obtained in varying proportions depending on the growth conditions and on the species being considered. For the first two species, vigorous vitroplants were obtained 2 to 3 months after transplanting to soil. Transplanting Acer saccharum microcuttings to soil brought their development to a halt.
