| The study aimed to evaluate the influence of overcoming dormancy of seeds of biribá through chemical and mechanical method in the emergence and initial growth of seedlings. The fruits were acquired from a mother plant in Cascavel (PR). The experimental design was a completely randomized in factorial 2 x 3, with four repetition, containing 25 seeds each repetition. The first factor was constituted of scarification with sandpaper n.80 of the two sides opposite the micropyle (with and without), the second factor was the soaking for 24 h (water, GA3 in the concentration of 1000 mg L-1 and without soaking). The count was performed for up to 60 days, being calculated the emergence speed index, average time of emergence and speed of emergence. When the... |

| The objective was to evaluate the effect of calcium silicate on the chlorophyll content and gas exchange of two tomato hybrids. The design used was in randomized blocks in a 2x5 factorial scheme, with four replications. The first factor was composed of two tomato hybrids: Ivety and Natália, and the second factor was composed of five doses of calcium silicate (0, 150, 300, 450, and 600 kg ha-1), applied to the substrate before planting the seedlings. Gas exchange: net CO2 assimilation rate (A), leaf transpiration rate (E), stomatal conductance (gs), internal CO2 concentration (Ci), water-use efficiency (WUE), intrinsic efficiency water use (iWUE), and instant carboxylation efficiency (ACi); SPAD index and the levels of chlorophylls a, b, and total were... |
