摘要:
为探讨大豆产量与根系性状之间的关系，以在冀中南地区夏播表现相对高产和低产的15个大豆品种为材料，采用盆栽方法，在出苗后20 d（苗期）、41 d（开花结荚期）、65 d（结荚鼓粒期）分别测定形态和生理性状。结果表明：根系鲜重、根总长、根体积和根系活力在不同取样时期两种产量类型间未达到显著差异，但两种产量类型间的根活形态指标及其增量在出苗后41 d和65 d均达到极显著差异，且与产量呈极显著正相关，特别是出苗后65 d的根活形态指标及增量与产量的相关系数更大，该期的相应根系指标可作为大豆高产育种在根系方面的参考。根活形态增量与产量具有极显著正相关，可用于生育期差异较大的材料之间的研究，进而对大豆产量相关根系性状的遗传研究提供了可行性指标。
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.
