1. Tolerance of crambe (Crambe abyssinica Hochst) to salinity and water stress during seed germination and initial seedling growth
RESUMO Crambe é uma oleaginosa adequada para vários fins industriais, como a produção de biodiesel, plásticos, borrachas e cosméticos. Há relatos da rusticidade desta espécie e seu potencial para o plantio em ambientes áridos e semi-áridos, onde a escassez de água e salinidade do solo são comuns. Entretanto, estudos sobre a tolerância de semente

2. Padrão de germinação de sementes e estabelecimento de mudas de guanandi (Calophyllum brasiliense Cambess.)
CHAPTER II: Calophyllum brasiliense Cambess. is a tree, typical of tropical rainforests, with seed germination variable and uneven due to restrictions of the layers of the integument. The objective was to characterize the dormancy of seeds of species by their ability to soak, germination, emergence, distribution of germination over time and the timing and qu

3. Impact of saline water stress on nutrient uptake and growth of cowpea
Soil salinity is a major limitation to crops production in many areas of the world. The present study reports the impact of salt stress on seeds germination, plant growth parameters and leaf ions accumulation in three cowpea Vigna unguiculata (L.) Walp Indian cultivars: Akshay102, Gomti vu-89 and Pusa Falguni. The electrical conductivity (EC) of the soil was

4. Estádio de maturação dos frutos, tratamentos pré-germinativos e variabilidade da emergência de plântulas de morototó (Schefflera morototoni)
The objective of this work was to evaluate the influence of the fruit maturation stage in the physical attributes and germination of Schefflera morototoni pyrenes subjected to pre-germination treatments. Fruits with green and purplish green coloration were collected from 14 individuals, pulped in running water, the hollow pyrenes were discarded after countin

5. RizobactÃrias para o tratamento de sementes: seleÃÃo, eficiÃncia em campo e modos moleculares de aÃÃo. / Rhizobacteria for cotton seed treatment: screening, field efficacy and molecular modes of action
Rhizobacteria may act on eradication of seed-associated pathogens and plant protection against biotic and abiotic stresses. The present work aimed to select rhizobacteria to control cotton diseases and assess the molecular modes of action involved. A total of 368 rhizobacteria were tested for the controlo f damping-off and bacterial blight by treating infect

6. Germinação, emergência da plântula, produtividade e qualidade da fibra de Gossypium hirsutum L. CV. DP 660 sob ação de bioestimulante / Germination, seedling emergence, productivity and fiber quality of Gossypium hirsutum L. cv. DP 660 under action of biostimulants
Cotton is the most important vegetable fiber for man who uses it as a raw material in the production of tissues which has intrinsic qualities unequaled to in other fibers. For this reason, the viability of the seed has been receiving special attention, since its quality is demonstrated in the subsequent cultures, in terms of uniformity, greater performance o

7. Inventário de espécies de pteridófitas de uma mata de galeria em Alto Paraíso, Goiás, Brasil e morfogênese dos gametófitos de Pecluma ptilodon (Kunze) Price e Campyloneurum phyllitidis (L.) C. Presl (Polypodiaceae)
This work presents a survey of pteridophytes species established in a Galery Forest, located in the right margin of Couros river, inside the Portal das Chapadas farm, in Alto Paraiso de Goiás country (140988S, 473597W, 1,164m in high), in the region known by Chapadas dos Veadeiros. The samples were collected at 15-day intervals, between June 2006 and June 2

8. Dry material losses and qualitative evaluation of corn grain stored in hermetic units / Determinação da perda de matéria seca e avaliação qualitativa de grãos de milho armazenados em bolsas herméticas
A significant increase in the grain sector has been observed over the last few years, leading to the expansion of the balance of trade. However, in various Brazilian States, storage systems are composed of old structures, precarious for storage which end up compromising the quality of the product during storage. In order for the sector to increase exports an

9. Variabilidade de cinco espécies arbóreas da região de cerrado do Brasil Central para medidas de germinação e emergência / Variability of five arboreous species of the Central Brazil cerrado region for germination and emergency measurements
Basic studies of seed germination and seedling emergence assume an important role within scientific researches due to the devastation and fragmentation of the native vegetation of the Cerrado. Thus, in the present study the processes of seed germination and seedling emergency were evaluated using the linear correlations among the measurements calculated for

11. Directed dispersal by ants and post-dispersal regenerative phase of the ruderal species Ricinus communis L. (Euphorbiaceae) / Dispersão direcional por formigas e fase regenerativa pos-dispersão da especie ruderal Ricinus communis L. (Euphorbiaceae)
Plant reproduction through seeds has two phases: the regeneration of the individuals of a population and the establishment of the adult plants. The regenerative phase consists of many stages, such as seed release, dispersal, dormancy/quiescency and germination, and seedling establishment, each with differences in duration an? in mechanisms according to the s

12. Use of thin films obtained by plasma polymerization for grain protection and germination enhancement
In this work, preliminary results of the use of hydrophobic thin films obtained by plasma deposition to protect grains and seeds are presented: grains coated by the films did not present biological degradation when stored in a saturated water vapor environment, but had their germination accelerated in the presence of water. A model that explains the differen
