Plants
are not uniform in their nutritional requirements, most of them survive under
adverse conditions of humidity, temperature, and nutrients. Because they are
genetically adapted to their habitats and even some varieties of the same
species show differences in absorption, translocation, accumulation and
nutrient use. This study is aimed at examining the phosphorus (P) status in the
different parts of wheat (Triticum
aestivum L.) plant and its influence on plant growth and P translocation in
a split-root soil culture. KH2PO4 was used as the source of
phosphorus for the different level of P application. Two recently BARI
developed wheat varieties namely BARI GOM 25 and BARI GOM 26 were used as
testing plants. . Result showed the growth parameter increased with the
increase of P application. Likewise, P uptake by wheat plant also increases
with the elevated P application. However, no significant differences were
observed between wheat varieties irrespective of growth and P uptake by wheat
plant. Moreover, elevated P concentrations in the shoot of wheat plants
probably provide more P for shoot unloading of P and for P assimilation in the
controlled roots. This phenomenon results in increased P concentrations in the
roots of wheat plants that mean translocation of P in the roots. These findings
indicate that the added soluble P increases the absorption of nutrients from
the soil solution. So, this study concluded that the application of elevated P
in split-root system is efficient both for increasing shoot development and
root growth and plays significant role in thePtranslocationwithin the wheat
plants.
