| O presente trabalho teve como objetivo fazer um estudo nos sistemas de produção de semente de cebola convencional e agroecológico. Foram acompanhadas três propriedades nos municípios de Candiota e Hulha Negra, RS, de produção agroecológicas e duas convencionais, sendo marcadas aleatoriamente seis unidades de amostragem, cada uma delas com dois metros sobre a linha de produção, em cada uma das propriedades. As variáveis estudadas foram peso de bulbo, diâmetro bulbo quantidade de bulbos por área, quantidade de hastes por bulbo, quantidade de flores por umbela, quantidade de sementes por flor, teor de água da semente, rendimento de sementes, germinação, primeira contagem, peso de 1000 sementes, envelhecimento acelerado, índice e velocidade de germinação e... |

| 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 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. |

| The growth of plant species can be affected by waterlogging. This process occurs as result of physiological changes that occur at the plants. The study aimed to comparatively evaluate the growth and expression of seed vigor of common bean genotypes subjected to soil waterlogging. For each of the genotypes IPR Tuiuiú and Carioca, treatments consisted of combining soil waterlogging for 12 hours or kept at field capacity, and plant sample collection times. Plant samples were collected at every 20 day intervals, being determined dry mass, leaf area and seed vigor. The plants of genotype IPR Tuiuiú showed higher growth and similar expression of seed vigor under soil field capacity. In plants of genotype Carioca, soil waterlogging did not affect growth and... |

| 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... |
