Studies on Assimilate Translocation in Relation to Yield in Groundnut

Labelled ¹⁴CO₂ was fed to the leaves of different branches during pod development and translocation of assimilated ¹⁴C was measured from different plant parts of groundnut (Arachis hypogea L.) cultivars. It was observed that cv. J-11 incorporated higher amount of ¹⁴CO₂ but the assimilate translocation to other plant parts was lesser compared to cv. M-13. During peak pod developmental stage most of the translocated ¹⁴C was recovered from the pods of M-13, while a small amount from the pods of J-11. It was suggested that the bold seed and high yield in M-13 may be due to better sink efficiency and partitioning of photosynthates as compared to J-11.
