中文摘要	为明确不同耐旱基因型大豆生理性状对不同降雨气候条件的响应,田间条件下,以耐旱型品种辽豆14和干旱敏感型品种辽豆21为研究对象,探讨半干旱地区阜新和湿润半湿润地区沈阳对两品种生理特性及产量的影响.分别比较大豆植株V4、R2、R4和R6时期的叶绿素含量、株高、植株各部位鲜重、干重.结果表明:一般而言,在湿润半湿润地区沈阳种植的大豆植株的叶绿素含量高于半干旱地区阜新.一般情况下,植株根、茎、叶、叶柄和豆荚的含水量均表现为,同一时期,同一品种,沈阳的值高于阜新,但部分取样时期处理间未达显著差异水平;品种对根含水量的影响则因取样时期和地点的不同而表现出差异;大豆植株茎、叶、叶柄、豆荚的含水量均表现为,同一时期,同一地点,耐旱品种辽豆14的值高于干旱敏感型品种辽豆21,但多数情况下处理间未达到显著差异水平.植株各部位器官生物量的变化表现为,除R4期植株的根生物量和茎生物量、R6期的豆荚生物量表现为,同一品种辽豆14阜新种植高于沈阳种植,且差异不显著外;其它各时期各器官的生物量均表现为,同一品种辽豆14或者辽豆21,沈阳种植均高于阜新种植.成熟期大豆植株的器官分配比例表现为:子粒 >荚皮 >根、茎.子粒的分配比例为,辽豆14 >辽豆21;而荚皮、根、茎的分配比例则为,辽豆21 >辽豆14.大豆单株荚数与产量变化相一致.干旱胁迫降低了单株荚数、每荚粒数、单株产量和小区产量却提高了百粒重.辽豆14的单株荚数、每荚粒数、单株产量和小区产量均高于辽豆21,但百粒重却低于辽豆21.本研究结果明确了耐旱型大豆应答干旱胁迫的生理优势,丰富了辽宁省大豆抗逆栽培的理论知识.
英文摘要	Field experiments were conducted to study the effects of different rainfall climatic conditions on the physiological characteristics of different soybean varieties. Compared the chlorophyll content, plant height, fresh and dry weight of soybean plant at V4, R2, R4 and R6 stages. Results indicated that, in general,the chlorophyll content of Shenyang located in humid and semi-humid area were higher than that of Fuxin located in semi-arid region. Generally,plant root water content,stem water content,leaf water content,petiole water content and bean pod moisture content had the similar change trends,the value of Shenyang in the same cultivar were higher than that of Fuxin, but the difference were not significant between some sampling periods,the effect of varieties on root water content was different at different sampling periods and locations. In general, stem water content,leaf water content,petiole water content and bean pod moisture content of soybean plants all showed that the value of Liaodou 14 was higher than that of Liaodou 21 in the same period and the same location, but in most cases it did not reach significant differences level between treatments. The changes of the biomass of different parts of the plant showed that, except for root biomass,stem biomass of R4 and bean pod biomass of R6, the value of Fuxin was higher than that in Liaodou 14 in Shenyang, and the difference was not significant The biomass of other organs in all stages showed that the value of Shenyang were higher than the value of Fuxin with the same variety, but only a few significant differences were found among the treatments. The organs distributed proportion of soybean plants at mature stage showed the order of seed >pod >root or stem. Liaodou 14 had higher seed distribution ratio than Liaodou 21,while showed lower the distribution ratio of the pods, roots and stems. This tendency of pods per plant was consistent with yield. Drought stress reduced the pods per plant,seeds per pods, yield per plant and plot yield, but increased the 100-seed weight. Liaodou 14 showed higher pods per plant, seeds per pods, yield per plant and plot yield than Liaodou 21, but lower 100-seed weight than Liaodou 21. Therefore, the results could clarify the physiological advantages of drought-tolerant soybean in response to drought stress and further enrich the theoretical knowledge of soybean resistant cultivation in Liaoning province.
