Equations were fitted to the data and the correlation coefficients (r) and levels of significance (F-test) were determined for LA, GLDM, PEDM, BDM, SDM, PDM, RDM and TDM as a function of age (DAE).
Differential allocation of photosynthates occurs among the organs of soybean during their development, with the roots (RDM) and leaves (GLDM) especially benefiting (Figure 2A).
The GLDM of the bean plants increased from 0.46 g [plant.sup.-1] at 8 DAE to a maximum value of 8.54 g [plant.sup.-1] at 44 DAE and decreased continuously thereafter until reaching 1.68 g [plant.sup.-1] at 65 DAE (Figure 2B).
The GLDM of soybean was lower than that of bean at the beginning of the vegetative stage, but their GLDMs did not differ at either 30 or 37 DAE (p [greater than or equal to] 0.05).
In the final partition of the soybean photoassimilates at 93 DAE, the proportions compared to 100% TDM are as follows: GLDM = 23%, PEDM = 9%, BDM = 9%, SDM = 15%, RDM = 31% and PDM = 13% (roots with the largest share).
In the final partition of the bean photoassimilates at 65 DAE, the proportions compared to 100% TDM are as follows: GLDM = 8%, PEDM = 5%, BDM = 1%, SDM = 14%, RDM = 20% and, PDM = 52% (pods with the largest share).
