Investigation of natural auxins and growth inhibitors markedly increases the response of oat coleoptile sections to lAA, though Schneider (1941) reported that first internodes were almost insensitive to sucrose. A study of this point, conducted with both coleoptiles and internodes, demonstrated beyond any doubt that the growth of first internodes as well as that of coleoptiles is strongly increased by sucrose i

A study of this point, conducted with both coleoptiles and internodes, demonstrated beyond any doubt that the growth of first internodes as well as that of coleoptiles is strongly increased by sucrose in the presence of lAA and that the optimum sucrose concentration is 2 per cent {Figure 14). w 3-0- "1 2-0 1-n I 2-5 Z-0 I t^ 1-0 (a) / \lAA50yl\ y / ~° Con. \ Avena coleoptile I I I I I I L _a (t) /7l I I I I I I I I I (c) IAA30y/\ o o^ Con. ° Sorghum first intern ode II I I \ \ I L Cd).
