1. Southern highland papaya (Vasconcellea quercifolia A. St.-Hil.): Do fruit ripening and harvesting time affect seed germination?
ABSTRACT. In this work, we report the effects of the harvesting time, the stages in fruit ripening and the influence of potassium nitrate in V. quercifolia seed germination. In addition, information about the storage period and light requirements is provided. Fruits were harvested at the beginning and at the end of the fruiting season, and they were classifi

2. PHYSIOLOGICAL PERFORMANCE OF Physalis angulata L. SEEDS TREATED WITH CHEMICAL PROMOTERS
RESUMO Physalis angulata L. (Solanaceae), conhecida popularmente como camapu, possui elevado potencial farmacológico e agroindustrial. No entanto, por ser uma espécie essencialmente silvestre, os estudos sobre a qualidade fisiológica de suas sementes ainda são escassos. Neste sentido, objetivou-se avaliar o desempenho fisiológico de sementes de P. angul

3. Dormancy overcoming and germination test in Piptadenia stipulacea (Benth.) Ducke seeds
RESUMO Piptadenia stipulacea (Benth.) Ducke apresenta germinação lenta e desuniforme, devido à dormência tegumentar, além disto, não há indicações padronizadas quanto à temperatura e substrato para condução do teste de germinação em laboratório. Objetivou-se avaliar métodos de superação de dormência, temperaturas e substratos na germinaç�

4. Germination of Crotalaria and Lupinus (Fabaceae) seeds submitted to different pre-germination treatments and their effect on enzymatic activity during early germination
Resumo A maioria das sementes de leguminosas nativas e selvagens têm um tegumento rígido e impermeável, o que causa dormência física e impede a germinação, mesmo se as condições ambientais forem favoráveis. O estudo avaliou o efeito de tratamentos de escarificação sobre a germinação e a atividade enzimática de sementes de Crotalaria longirost

5. Effects of chemical treatments and environmental factors on seed dormancy and germination of shepherd's purse (Capsella bursa-pastoris (L.) Medic.)
Shepherd's purse (Capsella bursa-pastoris) is a problematic weed in citrus orchards and crop fields in northern Iran. In a series of laboratory and greenhouse experiments, we evaluated the effects that treatment with gibberellic acid (GA3) and potassium nitrate (KNO3), as well as environmental factors, including temperature, the duration of pre-chilling (wet

6. Germination of Croton urucurana L. seeds exposed to different storage temperatures and pre-germinative treatments
O presente trabalho avaliou a germinação e vigor de sementes de Croton urucurana. 1) As sementes foram classificadas por cores (caramelo, cinza e preto) e foram submetidas a sete diferentes tratamentos pré-germinativos seguidos de incubação a 20ºC, 25°C e 20/30°C. 2) As sementes foram armazenadas em câmaras frias ou em temperatura ambiente por até

7. 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

8. 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

9. Seed germination responses of the medicinal herb Centella asiatica
The effect of several environmental factors on germination of medicinal herb Centella asiatica was investigated. Freshly harvested seeds of C. asiatica did not germinate even after gibberellic acid (GA3) treatment and exposure to different treatments with light qualities, while two-three months old seeds exhibited germination (82%) without pre-treatment at w

10. SUPERAÇÃO DA DORMÊNCIA DE SEMENTES E CONTROLE QUÍMICO DE CORDAS-DE-VIOLA (Ipomoea spp.) EM SOJA RESISTENTE AO GLIFOSATO
Morningglory is an annual plant reproduced by seeds. Seed germination occurs in streams during spring and summer making it difficult to control. Its occurrence has increased in soybean crops in southern states by the exclusive use of the herbicide glyphosate in weed control. This species has seed dormancy caused by impermeable to water, whose absorption is p

11. Germinação e produção de compostos fenólicos em plantas de Talinum triangulare (Jacq.) Willd (Portulacaceae) tratadas com homeopatia / Germination and production of phenolic compounds in plants of Talinum triangulare (Jacq.) Willd (Portulacaceae), treated with homeopathy
Talinum triangulare (Jacq.) Willd (Portulacaceae), a Brazilian specie of annual cycle, is used as food and in traditional medicine as a laxative, healing and in the treatment of measles and diabetes. Found in tropical environments, it is well adapted to hot and humid climate, and low soil fertility. The specie spreaded by seed and grows spontaneously, especi

12. Germinação de sementes e crescimento inicial de plântulas de Eschweilepia ovata (Cambess.) Miers., Trema micrantha (L.) Blume. e Ficus tomentella Miquel. / Germination of seed and early growth of seedlings of Eschweilera ovata (Cambess.) Miers., Trema micrantha (L.) Blume. and Ficus tomentella Miquel.
Several researches about germination of seeds and emergency of native species seedling have been accomplished, however, considering the great diversity of species of the Brazilian flora, the available information are still scarce. In that sense, the present study (L.) has as objective to develop protocols for the study of the germination and initial growth o
