Foram examinadas 1273 folhas, entre novas e adultas do pimentão - Capsicum annuum L., sendo 226 folhas testemunhas e o restante de plantas cultivadas em soluções nutritivas com deficiências de macronutrientes (N. Ca, K, Mg, S, P). Do total de 1273 folhas, 1120 apresentaram domácias do tipo "tufo de pelos" e suas variações, localizadas na face inferior do limbo, nas axilas da nervura principal com as secundárias. As principais modificações foram as variações na quantidade e distribuição dos pelos formadores da estrutura. Nas folhas testemunhas, os pelos das domácias se apresentaram mais longos, mais ondulados e mais grossos do que nas domácias das folhas do experimento.
This paper studies the differences between domatia of normal leaves of Capsicum annuum L. and leaves of plants cultivated with deficiencies of N, Ca, F, Mg, S e P. Were studied 1273 leaves, of all ages, 226 of them being leaves of normal plants. The domatia founded were of the type "en touffe de poils" according to the Chevalier's Classification (1941) and theirs variations, localizated on the dorsal side of the limb, on the axil of midrib with the secondaries oves. The principal modification was that in the normal leaves the hairs (trichomes) were longer, waver and thicker than those of deficient plants.
