Conteúdo: | Cassava (Manihot esculenta Crantz) is an important food crop in the tropics. It is widely used in drought-prone climates, but little is known about the mechanisms by which cassava responds to water deficit environments. Cassava genotypes from five climatic zones of Brazil were grown in greenhouse conditions and subjected to water deficit and recovery treatments during the vegetative growth stage. In response to waterdeficit, cassava leaves rapidly accumulated the plant hormone abscisicacid (ABA) and correspondingly halted leaf expansion growth. Young leaves accumulated more ABA than mature leaves. Recovery was rapid: one day after rewatering, ABA concentrations returned to control levels. Other studies indicated that stomatal closure also occurred early duringwater deficit and recovered rapidly after rewatering.
