Abstract

We present the water uptake ability of cowpea (Vigna unguliculata Walp)which has been regarded as one of the most drought resistant species amongthe pulse crops. It has been suggested that in the lower part of the stem,parenchymatous tissue for storing water has been developed for the functionof drought resistance. We confirmed that in this tissue, water amount washigh compared to the other stems by neutron radiography. Then the water uptakemanner was measured by positron emitting tracer imaging system (PETIS) using 18F labeled water produced by a cyclotron. Comparing the water uptakemanner of cowpea plant with that of common bean, cowpea plant was found tomaintain high water uptake activity after drying treatment, suggesting thehigh drought resistant character.
