摘要:
在盆栽条件下，研究了苗期水分胁迫对大豆器官平衡和产量的影响。结果表明：在苗期不同强度水分胁迫下，不同时期大豆各器官的物质分配比例不同。中度水分胁迫下收获期的器官平衡为：籽粒＞根＞荚皮＞叶片＞茎秆＞叶柄，两个品系辽51064和辽51095的叶片分别占16.31%、15.28%，籽粒分别占25.83%、28.92%，叶柄分别占6.27%、4.85%，说明大豆苗期适度水分胁迫可以改变大豆的“源-库”关系。中度水分胁迫下，辽51095生物产量和经济产量的相关系数最大（0.9956）。就产量而言，正常供水与中度水分胁迫的差异并不显著，与重度水分胁迫则差异显著。
Abstract:
The shortage of water has been the main factor that limits the yield of soybean.Understanding the growing law of soybean under the condition of water stress is of great importance to improve soybean yield.The effect of water stress at seedling on organ equilibrium and yield of soybean was studied under pot experiment with two soybean sister lines Liao 51064 and Liao 51095.The proportion of dry matter distributed to each organ in different growth period varied with the strength of water stress.Under medium water stress，the organ equilibrium in the harvesting time was：seed>root>pod shell>leaf>stem>petiole，and the leaf，grain and petiole for the two sister lines of Liao 51064 and Liao 51095 accounted for 16.31% and 15.28%，25.83% and 28.92%，6.27% and 4.85% of total biomass，which showed that it was helpful to improve the balance between “the source and sink”.Under medium water stress，the correlation coefficient of biological yield and economic yield was highest（0.9956）for Liao 51059.The soybean yield under normal water supply and medium water stress also significantly higher than that of heavy water stress.
