Abstract
Rht3-containing gibberellic acid (GA3) insensitive deembryonated wheat (Triticum aestivum L. var Cappelle Desprez .times. Minister Dwarf) aleurone, that can be made responsive to GA3 by low temperature, can also be rendered GA3 sensitive by preincubation with indoleacetic acid (IAA). The IAA-induced response for the dwarf selection is concentration-dependent, relatively sensitive, and similar in magnitude to that induced by low temperature. Other auxins also induce GA3 responsiveness to a greater or lesser degree. IAA has no apparent effect on the wild type (rht, tall) selection.This publication has 9 references indexed in Scilit:
