The foliar radiophosphorus 32-P application and its distribution in mungbean plant (Phaseolus radiatus L)

The experiment carried out in greenhouse were intended to investigate radiophosphorus 32-P distribution and accumulation in mung bean at various plant ages. Radiophosphorus 32-P was applied foliarly in the mung bean plant of several weeks (ie. 2, 4, 6, 8, and 10 weeks) of age. The sampling has been done within 6, 12, 18, and 24 hours after treatment. The relative phosphorus accumulation (%) in various parts of the plant ie. roots, stem, leaves, leave stalks, flower stalk, pods, and pod stalk was determined. The design used in the experiment was the randomized block design with factorial calculation. The experimental results points out that the 32-P was taken up by any plant organ. This highest mean value of 4.58%/g sample was observed in the leaves of 2 weeks of age; meanwhile the lowest mean value of 0.09%/g sample was obtained in the pods of 10 weeks of age.
