37. 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,

38. 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

39. 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

40. 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

42. 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

43. New Allyldithiocarbimates: Synthesis, Structure and Antifungal Activity against Phakopsora pachyrhizi and Hemileia vastatrix
Twelve tetraphenylphosphonium allyldithiocarbimates were synthesized and fully characterized by high-resolution electrospray ionization mass spectrometry (HR-ESI-MS), infrared and nuclear magnetic resonance (NMR) spectroscopies. The spectroscopic data indicated that the allyldithiocarbimate anions present Z configuration, as confirmed by X-ray crystallograph

44. A Escola Francesa de Geografia
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

46. 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

47. Synthesis of Glycerol-Derived 4-Alkyl-Substituted 1,2,3-Triazoles and Evaluation of Their Fungicidal, Phytotoxic, and Antiproliferative Activities
Herein, the synthesis of nine novel glycerol-derived 4-alkyl-substituted 1,2,3-triazoles, using the CuI-catalyzed alkyne-azide cycloaddition reaction as the key step, is reported. The triazoles were characterized by infrared and nuclear magnetic resonance (NMR 1H and 13C) spectroscopy and mass spectrometry. The nine prepared compounds were evaluated with reg

48. 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
