摘要
通过３年田间观测，比较研究了３种结荚习性不同的大豆品种（有限性铁丰２４号、亚有限性辽豆１０号、无限性沈豆Ｈ－５０６４）开花、结荚、鼓粒进程。铁丰２４号出苗后第６９．５天始花，花期１８．５天，植株中部先开花，渐次向上向下开放；辽豆１０号出苗后第５２．５天始花，花期３４天，植株下部先开花，渐次向上开放；沈豆Ｈ－５０６４出苗后第５４．０天始花，花期４０．５天，开花次序与辽豆１０号相同。铁丰２４号全株结荚率为３３．５３％、主花序、副花序、分枝的结荚率分别为３６．８４％、４８．９４％、２０．２９％，主要结荚部位在植株的中上部；相应地，辽豆１０号为３５．７１％、５５．８１％、２５．００％和０，中部结荚居多；沈豆Ｈ５０６４为２４．００％、３５．９２％、１２．１２％和６．６７％，豆荚分布均匀。铁丰２４号、辽豆１０号、沈豆Ｈ－５０６４分别在开花后第１０－１９天、１２－２２天、１５－２６天豆荚伸长较快，基本接近品种的固有长度和宽度；豆荚厚度增长因品种籽粒灌浆进程而异。３个品种自幼荚出现至豆荚长成所需时间基本相同（约６３天）。３个品种单粒的增重过程符合Ｌｏｇｉｓｔｉｃ方程，前期增重缓慢，中期加快，后期又减慢，分别在开花后第４９．?
Through field tests and observation in 3 years, comparative studies were made on flowering, pod setting and seed filling of three soybean varieties with different podding habits (Tiefeng No. 24,determinate; Liaodou No. 10, semi-determinate; Shendou H-5064, indeterminate). The time of initial flowering of Tiefeng No.24 cocurred at 69 days after emergency, and it flowered for 18.5 days, initial flowers appeared on the middle part of the main stem, then other flowers bloomed gradually up and down along the stom. The time of initial flowering of Liaodou No.10 occured at 54 days after emergency, it was 34 days of flowering season, the flowering order was basically from the lower to the upper.The time of initial flowering of Shendou H-5064 occured at 55 days after emergency, it had 40.5 days of flowering season, the flowering order was just the same as that of Liaodou No.10. The rate of pod set of Tiefeng No.24 was 33.53%, the rate of pod set of main raceme was 36.84%, those of subraceme and branch were 48.94%,20.29% respectively, the main position at whichpots set was on the upper part of the main stem; while those of Liaodou No.10 were 35.75%,55.81%,25.00% and 0, the main position at which pots set was on the middle partofthemainstem;thoseofShendouH-5064were24.00%,35.92%,12.12% and 6.67%, the pods were distributed balancely along the plant. The pod setting Tiefeng No.24, Liaodou No.10 and Shendou H-5064 increased faster from 10 days to 16 days,12-21 days and 15-26 days after flowering respectively, and reached the given length and width were approximately the same. The three varieties have a similar period of pod growth (63 days approximately). The seed weight accumlations of the three varieties could be modelled by Logistic equation. The highest rates of seed weight accumulation occoured at 49.4,53.3 and 56.6 days after flowering.
