Abscisic acid in immature apical tissue of sugar cane and in leaves of plants subjected to drought.
Abscisic acid was extracted from immature leaf and stem tissue of sugar cane. Mature leaves of well watered plants contained trace quantities of this hormone but plants subjected to drought accumulated relatively large amounts in their mature leaves. Extracts from wilting leaves contained a substance similar to or identical with (+)-phaseic acid.
