25. LIPID, PROTEIN AND CARBOHYDRATE DURING SEED DEVELOPMENT IN Araucaria angustifólia
ABSTRACT This study aimed to evaluate changes in germination and in the amount of carbohydrates, starch, proteins, and lipids of A. angustifolia seeds at different stages of development. Seeds were collected in the Cotyledonary Stage and Stages I, II, III and IV. Germination, moisture content, dry matter amount, and levels of carbohydrates, starch, proteins,

26. GERMINATION POTENTIAL AND VEGETATIVE PROPAGATION OF Aegiphila brachiata VELL
ABSTRACT The objective of this study was to evaluate the germination potential of Aegiphila brachiata (peloteiro) and its propagation through stem-cuttings, as well as how the age of parental plants and the application indolebutyric acid (IBA) and inoculant of Azospirillum brasilense influence adventitious rooting of the species. Thus, the physical character

27. DISINFECTION PROTOCOL AND IN VITRO GERMINATION OF SEEDS OF Dalbergia nigra
ABSTRACT The Atlantic Forest is a biome that has suffered anthropic actions, such as the extraction of hardwood, which can lead to the extinction of endemic species of great economic and ecological value, such as Dalbergia nigra. In this perspective, large-scale multiplication studies are necessary to contribute to the conservation of this species. The objec

28. Selection to high productivity and stink bugs resistance by multivariate data analyses in soybean
ABSTRACT Stink bugs that affect soybeans are responsible for significant losses in seed production, quality and germination potential, in addition to hindering the mechanized harvest. To develop insect resistant materials, the breeder can compile a selection index by factor analysis. Therefore, the objective of this work was to validate the use of factor ana

29. Avocado: Is it possible to produce two seedlings with one seed?
ABSTRACT It was evaluated the possibility to produce two seedlings per avocado seed, through the separation of cotyledons. Two seed lots from two different ungrafted trees were evaluated. From the first tree were obtained 60 seeds, and 50 from the second. Half the seeds of each lot had their cotyledons separated and then whole seeds and half-seeds were sown

31. FUZZY SLIDING-MODE TEMPERATURE-CONTROL SYSTEM FOR SOAKING AND GERMINATION OF RICE SEEDS
ABSTRACT The soaking and germination process of rice seeds is the starting point in rice cultivation in cold regions and has a significant effect on grain yield. Efficient techniques for controlling the water temperature in the seed tank are required to enhance germination quality. This paper introduces a fuzzy theory for designing a fuzzy logic-based slidin

33. Salt stress alleviation by seed priming with silicon in lettuce seedlings: an approach based on enhancing antioxidant responses
ABSTRACT Seed germination and seedling growth are the stages most sensitive to salt stress, which can induce ion-specific effects and oxidative stress. Although silicon (Si) has been known to improve plant defense systems against stressful-conditions, little is known about seed priming with Si and mechanisms of Si-mediated alleviation of salt stress in seedl

34. Fire cues and germination of invasive and native grasses in the Cerrado
ABSTRACT Fire-related cues may enhance seed recruitment in flammable ecosystems and differences in fire-germination responses of invasive vs. native species can drive the invasion process. We evaluated the effects of heat shock and smoke water solution treatment on seed germination of invasive (Melinis minutiflora, Urochloa decumbens, U. brizantha) and nativ

36. Evaluation of arugula cultivars and seed production in the organic system
Resumo: A produção de rúcula (Eruca sativa Mill.) no Brasil utiliza sementes produzidas pelo sistema convencional, não tendo disponibilidade de sementes orgânicas. O objetivo deste trabalho foi indicar as cultivares de rúcula de melhor desempenho durante a fase de produto comercial e avaliar a viabilidade da produção de sementes, assim como a germina
