Nitrogen Contents and Nitrogen Accumulation Rates of Different Plant Parts of Wheat at Anthesis and Maturity Periods Under Normal and High Temperature Conditions

Öz

This research was established to evaluate differences in nitrogen contents of different wheat plant parts at anthesis and maturity periods under normal and high temperature conditions. Two temperature regimes was provided by sowing at two different times (normal wheat sowing time and quite late time to receive warmer conditions) and two different irrigation regimes was applied to distinguish the impact of drought from temperature. Our investigations showed that amount of nitrogen accumulated at flag leaf (at anthesis and maturity), lower leaves (at anthesis and maturity) lower stem (at anthesis and maturity), husk-awn-axis (at maturity), grains (at maturity) and spike (at pre-anthesis, post-anthesis and maturity) was maximum under high temperature conditions.

Maximum nitrogen content was at lower leaves both at anthesis and maturity. Minimum nitrogen content was at lower stem at anthesis and at flag leaf at maturity. If we compare different temperature regimes, nitrogen content was higher at high temperature and lower at normal temperature both for anthesis and maturity at all plant parts except lower stem at maturity. Nitrogen harvest index was reduced both by high temperature and irrigation. Amount of nitrogen at grains was maximum at high temperature- conditions. Nitrogen accumulation rateof whole plant was three times faster at pre-anthesis and two times faster at whole vegetation stage under high temperature regime compared to normal temperature regime.
