【摘要】 通过设置不同播期和光照处理,研究了中豆33和中豆34的光周期反应特性,并与其他品种进行了比较。研究结果表明,与早、中熟夏大豆品种相比,夏播时中豆33和中豆34全生育期较短,主要是因其生殖生长期较短,但仍然有较长的营养生长期。中豆33营养生长期对短日照更敏感,而中豆34生殖生长期对短日照更敏感。更多还原

【Abstract】 Photoperiodisms of soybean varieties Zhongdou No.33 and Zhongdou No.34 were studied and compared with those of other soybean varieties under different sowing dates and day-lengthes.The results indicated that growing periods for both Zhongdou No.33 and Zhongdou No.34 sown in spring were shorter than those for varieties with early or middle-maturing sown in summer,mainly because of their shorter reproductive growth.The vegetative growth of Zhongdou No.33 and the reproductive growth of Zhongdou No.34 were sensitive to short day-length.更多还原
