Abstract
abstract Nitrate absorption and utilization vary among plant species and varieties but there is little information on the nitrate uptake effectiveness of triticale ( X Triticose. cale, Wittmack), wheat ( Triticum aestivum L.), and rye ( Secale cereale L.). The nitrate uptake effectiveness of different cultivars of triticale, wheat, and rye were investigated in a growth chamber, using nutrient solutions. Plants were grown in pots containing the same base solution for 28 days before being transferred to solutions containing different nitrate concentrations. The solutions contained 0.1, 1.0, 2.5, 5.0, and 10.0 m M nitrate. Increasing nitrate concentration from 0.1 to 2.5 m M increased plant dry matter and N uptake. Few significant differences were observed at nitrate concentrations greater than 2.5 m M . Root uptake coefficients decreased with increasing nitrate concentration. Triticale '6TA 385', 'Arthur' wheat, and 'Abruzzi' rye showed higher effectiveness than triticale '6TA 203', 'Atlas 66' wheat, and 'Vitagraze' rye in the uptake of nitrate at 0.1 and 1.0 m M nitrate concentrations but these differences were not obtained at higher nitrate concentrations. Varietal differences within species indicated that triticale, wheat, and rye had similar nitrate uptake effectiveness.
