Title

RESPONSES OF WHEAT CULTIVARSTO NITRATE UPTAKE

Pages

  4-23

Abstract

 At the start of growing season, nitrate concentration in soil is high. Therefore, during the autumn, organic N will be converted to inorganic N, and at this time, N fertilizer is added to soil. The optimum use of this amount of nitrogen will be useful. There fore, some WHEAT cultivars were studied in a serie of experiment using a hydroponic culture system for the NITRATE UPTAKE and analysis. Seedlings were grown at two rates of nitrates (0 and 1.0 mm) and were compared in a 26 day growth period. Results indicated that a significant difference exists between WHEAT cultivars for the NITRATE UPTAKE. Atila and yavarous cultivars absorbing higher amount of nitrate produced larger seedlings, compared to the falat, star and sarasari 11 cultivars which produced smaller seedling and took up lower amounts of nitrate. According to difference among cultivars for seedling vigor, the results indicated that the first group including Atila, Chenalter, Sarasari 20, Yavarous, and Sarasari 11 had more physiological efficiency in nitrate consumption. According to absorbed nitrate, the amount of produced dry matter by the cultivars of this group was higher. On the whole we can say that genetic variation in nitrate absorption among WHEAT cultivars is due to a modification in plant size and specifically the root system.
