Creator:: Sepaskhah, Ali Reza
Abstract:: The effect of soil temperature and plant water stress on nitrogen uptake, growth rate and transpiration rate of wheat (Triticum aestivum VILL. , Host) seedlings was studied. A special apparatus for the control of plant water stress and root temperature was used. Leaf area was measured by the air flow...

Creator:: Akratanakul, Wanee
Abstract:: A growth chamber experiment was conducted to determine the rate of S-urea mineralization and effect of S-urea on the yield of ryegrass (Lolium multiflorum) grown in Steiwer soil as influenced by soil temperature (60, 75, and 90° F) and soil moisture stress (0. 10, 0.35, and 2.50 bars). Plant yield,...

Abstract:: The effects of a range of thermoperiods and soil temperatures upon growth of Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) seedlings were studied. The seeds, of varieties glauca and menziesii, came from eight widely separated areas. Plants from both varieties made maximum growth with soil and air temperatures between 18 and 24...

Creator:: Fazilat, Mohammad
Abstract:: The effect of soil temperature and soil water suction on the rate of phosphorus uptake and growth rate of wheat (Triticum aestivum VILL. , Host) was studied. Plants were grown in perlite slabs separated from an osmotic solution by a semi-permeable membrane. Measurements were made at temperatures of 10.0, 18.3,...

Abstract:: Air temperatures at i m and soil temperatures at 2C cm are reported for twenty-one forest stands in the central Western Cascader of Oregon. Records began in 1970 for some stands, in 1971 or 1972 for most. Temperature Growth Index for a stand, based on temperature effects on Douglas-fir seedling...
