Seleção de progênies de nabo-forrageiro para germinação sob altas temperaturas

Due to the expansion of the wild crop to regions with higher temperatures is important to develop cultivars adapted to high heat. The aim was to select tests for evaluating seed physiological quality of wild radish to estimating genetic characters in order to select cultivars adapted to high temperature conditions. Hundred of half-brothers of wild radish were subjected to germination test and vigor (first count of germination, classification of seedling vigor, accelerated aging test, germination and testing of the first count at high temperature as well as seedling emergence in field. The germination test, first count test, accelerated aging and high germination test (20-35°C) can be used for the selection of wild radish crop populations adapted to germination and field emergence under high temperatures.

Assessment of the physiological potential of spinach seeds (Tetragonia tetragonoides (Pall.) Kuntze)

The efficiency of vigor tests in assessing the physiological potential of seeds depends on their standardization for different species. In this context, the research aimed to study specific methodologies to evaluate the vigor of spinach seeds (Tetragonia tetragonoides). For this purpose, five lots of spinach seed cv. New Zealand were submitted to germination, first count of germination, seedling emergence in the field, accelerated aging (with and without use of saturated solution of NaCl at 41and 45 ºC for 24,48 and 72 hours), controlled deterioration (18,21 and 24% seed water content adjustments for 24 hours at 45 ºC) and electrical conductivity tests with variations inwater volume (25, 50 and 75 mL), seed quantity (25 and 50) and soaking period (1, 2, 4, 8,12, 16 and 24 hours) at 25 ºC. The first count test allowed obtaining preliminary information about seed vigor, and other tests in general showed similarity with seedling emergence in the field. Thus, it was concluded that traditional accelerated aging test 24 h /41 ºC and accelerated aging test with saturated salt solution for 24 h at 41 ºC and 45 ºC, and controlled deterioration test with 21% seed water content / 24 h / 45 ºC were all efficient for evaluating the physiological potential of spinach seeds.

Análise da influência da concentração de feixeis de fibras de bambu em ensaios de piso

Bamboo has one of the highest growth rates among plants, however, its lignifications (which confers resistance) takes around a few years and, therefore, certain physical characteristics and mechanical, that depend on this process will only be acquired between the three to six years old. In addition, bamboo also has significant density variations in different parts of the stem, both in the radial direction as the axial. In particular the radial direction, where the density found in the inner and outer (near the bark) of a single stem can range on average from 0.5 to 0.9 g/cm3. Thus, the application of bamboo as a floor, there to examine whether both sides of the bamboo (internal and external), provide resistance properties required for that purpose. In this study sought to characterize and quantify the influence of the concentration of fiber bundles in the inner and outer sides of rules or bamboo strips of bamboo flooring through testing service. Analyses performed were based on ASTM D 2394- 83 for wooden floors and derivatives. This was necessary because of the absence of a specific prohibition of the use and testing of floors made of bamboo and its products. The data were analyzed by ball indentation test shooting, test for resistance to abrasion, indentation test for stress / load treadmill test and by indentation loads applied to small areas - test the jump. The results of the tests were extremely friendly bamboo, even this presents considerable differences between the resistances obtained from assay of the cover of the inner and outer face, being comparable with those of many commonly used to manufacture wood flooring. This comparison was made possible by information from technical trials of several floors made with wood
