| This study aimed to evaluate the early growth stages of irrigated rice (Oryza sativa L.) seedlings from cultivars SCS-112, BRS-7 Taim, BR IRGA 410 and IRGA 417, under three different temperatures, i.e. 15, 20 and 25 °C, as a result of seed imbibition in a gibberellic acid (GA3) solution at concentrations of zero, 150, 300, 450, 600 and 750 mg L-1. The lengths of the shoot and the primary root of seedlings were recorded at three, seven and 21 days from sowings on germination paper. Interactions between the main factors were observed for all the response variables. Rice cultivars have differential sensitivity to variation in the concentration of gibberellic acid on seed treatment according to the temperature and the time of evaluation. Cultivar BRS-7 Taim... |

| The objective of this study was to evaluate the physiological performance of seeds and seedlings of tomato under the influence of different temperatures. The experiment was conducted in the Didactic Laboratory of Seed Analysis – ERS, UFPel. Gaúcho® tomato seeds were used. Treatments consisted of the constant temperatures 18, 20, 22, 24 and 26 ºC. To determine the physiological performance of the seeds and seedlings were employed germination assessments, first count, germination speed index, accelerated aging, cold test, shoot and primary root length, dry matter of roots and shoots, seedling emergence at 14 and 21 days after sowing, and emergence speed index. The results showed that tomato seed germination is not affected by the temperatures 18 to 26 ºC.... |

| The soil waterlogging reduces oxygen content near the roots, affecting energy metabolism and absorption of water and nutrients. Thus, the objective of this study was to evaluate the effect of different periods of soil waterlogging on physiological characteristics of initial growth in oat plants. The treatments consisted of soil in field capacity and soil flooding for 72 and 120 hours, with six replications. To analyze the initial growth were observed the number of leaves, leaf area, leaf area ratio and leaf weight, specific leaf area, dry weight of leaf, stem and roots, length of shoot and primary root. The increasing of the period of flooding reduced the accumulation of root dry matter, the leaf area and the specific leaf area. However, the length of... |

| The objective of this work was to evaluate the influence of the level of artificial defoliation, applied in stages V6 and R2, on the quality and yield components of soybean seeds. The experiment was conducted in a greenhouse in the municipality of Cascavel, Paraná State, Brazil. The experimental design was a randomized block with four replications, in a 5 x 2 x 2 factorial scheme (five levels of defoliation x two cultivars, two phenological stages (V6: fifth fully developed trifoliolate leaf and R2: full flowering), two growth habits). The analyzed variables were mass of 100 seeds, number of pods per plant, seed number per plant, seed number per pod, germination, dry matter of seedlings and length of shoot and roots of seedlings. Defoliation above 50%... |

| The study aimed to comparatively evaluate the partition of assimilates between biometrics and two cultivars of pepper over the crop cycle. Plants were collected from the fourteenth day after transplanting (DAT) at regular intervals of fourteen days after the transplant by the end of the crop cycle. Evaluations were made of dry leaves (Wf), stem (WC), root (WR), fruit (WFR) and the rate of dry matter production of leaves (Cf), stem (CC), root (Cr), fruit (CFR), number of leaves and plant height. The cultivar Vulcão presented a higher allocation of dry matter in leaf, stem and root, but the Doce gave a higher dry matter accumulation in fruit which is the part of commercial interest. |
