| Abstract/Contents: | "Kentucky bluegrass was grown for 4 months in solution culture before treatment with standard nutrient solutions modified as follows. Carbowax 1000 was added to produce osmotic pressures varying from 2.6 to 9.6 atm. Aqua-Gro was applied at rates to produce surface tensions of from 35 to 45 dynes/cm. Hexadecanol was added at rates from 25 to 200 pounds/acre. Effects of these solution modifications on growth of foliage and roots were determined. Osmotic pressures of the nutrient solution above 6.0 atm. were extremely detrimental to plant growth. Production of foliage was increased up to 2.5 atm. when greenhouse temperatures were within the range of 70 to 80° F. Decreases in surface tension decreased fresh and dry weight yields of foliage. Hexadecanol increased fresh and dry weight yields of foliage. Root development was increased with increasing osmotic pressure and decreased with decreasing surface tension. Hexadecanol in the nutrient solution stimulated root growth. Variations in osmotic pressure and surface tension of root zone solutions affect turfgrass production. Turf response to Hexadecanol was favorable." |
