Adequate dry matter production
of plants is a very important event for producing higher grain yields under
high temperature stress. We established a field trial to measure differences in
dry matter accumulation of different plant parts of wheat under normal and high
temperature conditions. Two temperature regimes were provided by planting at
two different times (normal wheat sowing time and quite late time to receive
warmer conditions). Also two different irrigation regimes has been applied to
distinguish the impact of drought from temperature.
As a result of trials, dry matter content was maximum at
lower stem and minimum at flag leaf both at anthesis and maturity. When
different growth conditions compared, total dry matter content was lowest at
high temperature rainfed conditions except lower leaves at maturity. This value
was maximum at normal temperature rainfed condition at anthesis and high
temperature irrigated condition at maturity. Instead of existence of enough dry
matter for producing high grain yield levels, harvest index was minimum under
high temperature irrigated condition. As a result, grain yield was minimum
under high temperature irrigated condition (4.65 t/ha). Grain yield was maximum
at normal temperature rainfed condition (6.20 t/ha). This indicates an
exsistance of a problem other than adequate dry matter production to produce
more yield under high temperature conditions.
