• The hypothesis that there is an intimate relationship between gibberellin levels and plant stress protection has been tested using near-isogenic lines of a normal and dwarf barley(Hordeum vulgare L.). Application of paclobutrazol(a triazole), induced stress protection in the normal line and application of GA_3 to the dwarf reversed the inherent stress tolerance. Reversal of the dwarf phenotype by specific gibberellins(GAs) suggests that the conversion of GA_<20> to GA_1 and GA_9 to GA_4 has been compromised. These observations indicate that modulation of specific GAs plays a key role in stress protection. The preferential use of non-chemical technologies including enzyme regulation, phytochrome A overexpression, and breeding for induction of stress tolerance in plants are discussed
