Ecophysiological studies under semi-controlled conditions in nurseries and greenhouses are essential to enable the use of native species to recover degraded areas and for commercial planting. Talisia subalbens (Mart) Radlk, 'cascudo', is a native fruiting species of the Cerrado on the verge of extinction. The ecophysiological performance of this species was evaluated in nursery conditions under different levels of shading (full sunshine, 30%, 50% and 70%). Initial growth, biomass allocation, gas exchange and chlorophyll content of the plants were analyzed. Full sunshine cultivated plants showed a higher accumulation of total, shoot, and root dry biomass. There was no significant difference in the root/shoot ratio among the treatments. Seedlings cultivated under full sunshine and 30% shading showed higher values for height, basal diameter, and leaf area. Differences in stomata conductance and photosynthesis rate were not observed among the different shading levels. Plants cultivated under 70% of shading had higher contents of chlorophyll a, b, and total. During the initial phase with higher levels of radiation were fundamental for the development of T. subalbens seedlings.

SUMMARYStructural changes occurring in meristematic cells of barley {Hordeum vulgare L. cv. California Mariout) in response to moderate salinity treatment were studied. In the apical region of the root, salt caused an increase in vacuolation which may provide a means for accumulation of excess ions. Salt treatment also caused many plastids in the cortical cells in this region to adopt varying amoeboid shapes, often appearing to enclose part of the cytoplasm which was less dense than the surrounding cytoplasm. This suggested that plastid morphology may allow or alternatively result from adaptive changes in protein synthesis or cytoplasmic composition.

INTRODUÇÃOMuitos métodos têm sido desenvolvidos para avaliar o estado nutricional das plantas. Uma dessas técnicas em que se analisam determinadas folhas em períodos definidos de crescimento da planta, é a diagnose foliar, que consiste em analisar o solo usando a planta como solução extratora (MALAVOLTA et al., 1989).A redutase do nitrato, enzima induzida por molibdênio e pelo substrato, tem sido utilizada para avaliar o estado nutricional com respeito ao N (BAR- AKIVA & STERBAUM, 1965;BAR-AKIVA et al., 1970). É que existe, dentro de limites, correlação positiva entre suprimento de nitrogênio, atividade da enzima e produção.O presente trabalho teve como objetivos avaliar o estado nutricional do feijoeiro (Phaseolus vulgaris L. cv. Carioca), cultivado em solução nutritiva, através da diagnose foliar e de um teste bioquímico para N (redutase do nitrato). MATERIAL E MÉTODOSO feijoeiro (Phaseolus vulgaris L.) cultivar carioca foi cultivado em solução de
