Conteúdo: 	Leaf samples taken from fruiting and nonfruiting terminals of guava trees (Psidium guajava L.) were analyzed chemically to observe the variation in chemical composition as affected by position in the terminals. Phosphorus, potassium, and nitrogen decreased definitely with age while calcium, magnesium, manganese, sodium, and aluminum increased with age. The other nutrients determined were somewhat variable, but boron tended to decrease at the beginning with an increase in the middle positions. Not too much difference was observed between fruitig and nonfruiting and nonfruiting terminals. Chemical compositions tended to level off between the fourth and seventh positions in the terminals.
