Abstract:
For probing into the developing relation between reproductive yield and root trait in soybean，fifteen summer soybean varieties with relative higher and lower yields in mid-south of Hebei province were used for researching on root traits by pot experiment.At 20，41，65 days after emergence，the root morphological and physiological traits were determined.Results showed that root fresh weights，root total lengths，root volumes and root reductive activities were not significantly different between two yield types；while the root-active-morphological traits(RAMT)，namely，the products of root reductive activities and root fresh weights，root total lengths，root volumes，respectively，were significant different at 41，65 days after emergence between two yield types，and the same as the increments of the RAMT.The RAMT and their increment were significant positively correlated with yield at 41，65 days after emergence，especially at 65 days after emergence.The RAMT and their increment could be used for the research among verities which had much diversity of growth periods，and further could be used for genetic research on the soybean root trait correlated with yield.
