| 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... |
