| 中文摘要: |
| 以来自国内不同生态区的57 份大豆种质和来自国外的10 份大豆种质为试材，分春、夏两季进行播种，研究播期对不同大豆种质生育期的影响。结果表明，春播条件下，与原生育期相比，16 份种质的生育期缩短，12 份相差5 d 之内，39 份生育期延长。生育期缩短的种质中，绥农6 号缩短天数最多，达33 d；生育期延长的种质中，盘石豆延长天数最多，达54 d。夏播条件下，与原生育期相比，27 份种质的生育期缩短，28 份相差5 d 之内，12 份生育期延长。生育期缩短的种质中，吉育30 缩短天数达55 d。与春播相比，夏播时，大豆全生育期缩短，主要是生育前期的缩短，即播种至结荚阶段的缩短。从积温角度来说，夏播大豆比春播大豆全生育期所需积温减少，主要是开花和结荚期减少，而在其他发育阶段两者差异不显著。 |

| Total of 67 soybean germplasms，including 57 internal ones and 10 foreign ones，were sowed
in spring and summer，respectively，to study the effects of sowing date on growth period of different soybean
germplasms. The results showed that compared with the original growth period，as to the germplasms sowed in
spring，the growth periods of 16 germplasms got shorter，12 germplasms varied < 5 d，and 39 germplasms became
longer. The biggest reduction in growth period of 33 d occurred in germplasm，Suinong No. 6，and the biggest
increase in growth period of 54 d occurred in germplasm Panshidou. Compared with the original growth period，as
to the germplasms sowed in summer，the growth periods of 27 germplasms got shorter，28 germplasms varied < 5
d，and 12 germplasms became longer. A significant reduction of growth period of 55 d happened in germplasm Jiyu
30. Averagely，the growth periods of germplasms sowed in summer were shorter than those of germplasms sowed in
spring，because the germplasms sowed in summer possessed a shorter period at the flowering and podding stages. In
term of accumulated temperature，the soybean sowed in summer averagely needed less than those sowed in spring.
The reduction of need for accumulated temperature for soybean sowed in summer mainly occurred during flowering
and podding stages. |
