摘要: During the dry and rainy seasons, determinations of stomatal resistance transpiration five tropical crops were carried out: guarana (Paullinia cupana Kunth), coffee (Coffea arabica L.), cashew (Anacardium occidentale guava (Psidium guajava L.) rubber (Hevea brasiliensis Muell. - Arg.) trees. Experimental design was done at randomized complete blocks with replications. season there a decrease in values following order: > coffee> cashew> rubber, from 2.5 to 30.0 s.cm-1. varied 1.5 3.0 The showed higher water when compared other crops. season, tree continued present lower and, consequently, transpiration.
