2. Immediate and latent effects of drying soybeans with dehydrated air
ABSTRACT. New grain drying techniques have been improved to reduce post-harvest losses. The electric air dehumidifier (UTA 60®) is an example; it was installed at the ELLITT Seed Company for drying soybean seeds (TEC 7849) with random sample collection (DIC). Our objective was to evaluate the immediate and latent effects of the dehumidified air on the vigou

3. Physiological maturation in seeds of Lophantera lactescens Ducke
RESUMO Lophantera lactescens Ducke (Malphigiaceae) é uma planta arbórea que se propaga por sementes, exclusiva da região amazônica, mas amplamente distribuída na América do Sul. Diante disto, objetivou-se estudar o processo de maturação de sementes de L. lactescens, visando determinar o ponto de maturidade fisiológica e o momento adequado para a col

4. GERMINATION AND VIGOUR IN SEEDS OF THE COWPEA IN RESPONSE TO SALT AND HEAT STRESS
RESUMO A salinidade é prejudicial ao desenvolvimento vegetal, causando diferentes danos às espécies, ou até mesmo entre genótipos da mesma espécie, com os efeitos sendo agravados quando combinado a outro estresse, como o térmico. Objetivou-se avaliar a tolerância ao estresse salino de genótipos de feijão-caupi (Vigna unguiculata L. Walp.) em difere

5. Processing and physical and physiological quality of the native forest seeds of Vernonanthura discolor
ABSTRACT. The objective was to study the processing of Vernonanthura discolor seeds, evaluating their physical and physiological qualities and defining parameters for purity analysis and determine the weight of one thousand seeds. The seeds extracted from the infructescences were processed in a blower, testing combinations of openings of the calibration valv

7. Exploitation of trichoderma species on the growth of Pythium Aphanidermatum in Chilli
Damping-off of chilli caused by Pythium aphanidermatum is a major nursery disease in vegetables. In vitro experiments evaluated the effect of eight isolates of Trichoderma species (from chilli rhizosphere) were tested against P. aphanidermatum. All the Trichoderma species had varied antagonistic effects against the pathogen. Among them, TVC3 recorded maximum

8. Changes in seed quality during fruit maturation of sweet pepper
Studies regarding seed maturation are important to determine the ideal fruit development stage for harvesting in order to obtain high-quality seeds. Changes in sweet pepper (Capsicum annuum L.) seed quality were monitored during seed development in order to identify the stage of maximum quality of the seeds and the optimum harvest date. Fruits harvested from
