SUMMARY Abscisic acid levels were measured in turgid or wilted detached leaves from maize and sorghum seedlings. Lines, cultivars and hybrids known to exhibit different abilities to withstand water stress were compared. The leaves of those tolerant to drought were shown to contain substantially more free abscissic acid. The effect was more clearly shown by sorghum than by maize. The results are discussed in relation to the physiology of drought tolerance.
