Photosynthesis by fruit walls of lablabbean (Dolichos lablab L.) and their role in seed devlopment

Studies were conducted to assess the role of pods in photosynthesis and seed development using ¹⁴CO₃. The fixation varied with the developmental period. Young pods fixed more or ¹⁴CO₂ than the old ones. The assimilation in seeds increased with passage of time. Maximum translocation was at 10 days after anthesis followed by 30 days, suggesting the possibility of higher translocation after 20 days. Observations onethanol insoluble fractions supported the present findings.
