1. Seed Germination and Seedling Vigor of Magonia pubescens
ABSTRACT The timbó (Magonia pubescens A. St.-Hil.) is a tree species of the family Sapindaceae occurring naturally in the Cerrados of Central Brazil. The objective of this study is to verify the influence of seed size, pre-soaking time in water and seedling production containers in the development of timbó seedlings. The experiment was completely randomize

2. Simulacao de estiagem na emergencia e no crescimento inicial de cultivares de algodoeiro herbaceo.
O presente trabalho constou do estudo do efeito de deficit hidrico sobre quatro cultivares de algodoeiro herbaceo (Gossypium hirsutum L.), com ou sem pre-embebicao das sementes, e de dois niveis de umidade do solo, ou seja, mantendo-a ao nivel de capacidade de campo ate a semeadura ou ate a emergencia das plantulas, sem irrigacao posterior. O estudo foi real

3. Aperfeiçoamento do uso de hipoclorito de sódio para acelerar a germinação de sementes e a emergência de plântulas de cafeeiro (Coffea arabica L.) / Improved use of the sodium hypochlorite to accelerate the seed germination and emergence of the coffee seedling (Coffea arabica L.)
This study aimed at the evaluation of the effect of sodium hypochlorite concentrations in the aqueous presoaking solution of the coffee seeds with moisture content from 10 to 33% upon the performance of those seeds under laboratory conditions, the emergence of the seedlings under nursery conditions, as well as to evaluate the development of the seedlings.

4. Imbibition of soybean seeds for germination test / EmbebiÃÃo de sementes de soja para o teste de germinaÃÃo
A cultura da soja tem grande importÃncia econÃmica no cenÃrio agrÃcola brasileiro, sendo que a produÃÃo de sementes contribui significativamente com este processo. MÃtodos e testes de avaliaÃÃo da qualidade das sementes que realmente expressem o seu potencial sÃo de grande valia. Esta pesquisa teve por objetivo buscar uma metodologia alternativa ca

5. Possible Involvement of the Alternative Respiration System in the Ethylene-stimulated Germination of Cocklebur Seeds
Respiration of nondormant upper cocklebur (Xanthium pensylvanicum Wallr.) seeds was enhanced by exogenous C2H4, proportionally to the concentration of C2H4 and the duration of presoaking of the seeds. Benzohydroxamic acid (BHM) and salicylhydroxamic acid (SHM), inhibitors of alternative respiration, inhibited both the germination of nondormant lower cocklebu

6. Control of Enzyme Activities in Cotton Cotyledons during Maturation and Germination: I. Nitrate Reductase and Isocitrate Lyase 1
Actinomycin D at 10 μg/ml strongly inhibited the increase in isocitrate lyase activity during germination of seeds and 40-day-old embryos of cotton (Gossypium hirsutum L.) when the germination period was preceded by 3 hours of soaking in the inhibitor solution. No inhibition was observed without the presoaking. Induction of nitrate reductase activity by nit
