Alterações morfológicas e citológicas do cafeeiro (Coffea arabica L, var. Bourbon (B. Rodr.) Choussy) cultivado em solução nutritiva decorrentes das deficiências e excessos dos macronutrientes

The present work was carried out in order to study: (1) the symptoms of deficiency and excess of macronutrients (N, P, K, Ca, S, Mg) in the coffee plant (Coffea arabica L. var. Mundo novo); (2) the modifications induced by those treatments in the hystological make up of the leaves; (3) the effects of deficiency and excess on the growth and in the chemical composition of the plants. Young coffee plants were grown in nutrient solution, three treatments being used, namely: complete solution (HOAGLAND & ARNON, 1950), deficient solution, in which a giVen element was omitted, and solution with 3 times the concentration of the element under study. The main conclusions can be summaryzed as follows. 1. SYMPTOMS. Clear cut symptoms of malnutrition were observed in the treatments: -N, -P, +P, -Ca, -Mg, -S and +S; the signals - and + stared respectively for deficient and excess level. 2. HISTOLOGICAL EFFECTS. The most definite alterations took place in the treatments +P, -Mg and +S. Usually the characteristics of the chloroplasts were affected: loss of the green color and coalescence into irregular bodies.

Ultramorphology of the metapleural gland in three species of Atta (Hymenoptera, Formicidae)

Differences among the metapleural glands of four female castes of Atta bisphaerica Forel, 1908, A. capiguara Gonçalves, 1944 and A. sexdens rubropilosa Forel, 1908 were examined by scanning electron microscope. There were no differences in gland size between the same castes of these species, although the opening gland in A. sexdens rubropilosa had been twice as large as A. bisphaerica. The relative size and functional significance of the metapleural gland among different castes is discussed and similarities between these and the other Formicidae till now studied is presented.
