本文探讨和分析了干旱胁迫对大豆发育种子脂肪酸含量的调节。试图为大豆高脂肪酸及优质脂肪酸育种提供基础参数。材料与方法试验材料:牡辐4219～2,黑农31,黑农32。盆植方式,将材料播种于淋溶黑土与粗砂按4:1Wt/Wt混匀,且以5×10~(-4)比例拌入三料肥,盆底铺2.5公斤砾石,在砾石上面填充1.25公斤粗砂,以构成透水层。每盆种4株。据大豆不同时期需水指标,以满足大豆生育对水分的需求,于大豆主茎最大叶着生节的第一朵花开放之日起记载,开花后第10天午后1点钟取样,以主茎最大叶节上、下各荚共5个荚的子粒。取样后,将样品干燥至恒重。每次取样,间隔5天,第1次取样后的第三天要进行干旱处理。每次取干旱、不干
This article explored and analyzed the regulation of the fatty acid content of soybean seeds under drought stress. Trying to provide basic parameters for soybean high-fatty acids and high-quality fatty acid breeding. Materials and Methods Test Materials: Mu-spun 4219 ~ 2, Heinong 31, Heinong 32. Potted plants, the material sowed in leaching black soil and coarse sand by 4: 1Wt / Wt mix, and the proportion of 5 × 10 ~ (4) into the three fertilizer, pelvic floor shop 2.5 kg gravel, above the gravel Fill 1.25 kg of grit to form a water-permeable layer. 4 plants per pot. According to different water demand indicators of soybean in order to meet the demand of soybean growth of water, the largest leaf of the main stem of soybean leaves with the opening of the first flower recorded on the 10th day after flowering at 1 o’clock sampling, the main Stems the largest leaf section, the next pod a total of five pods of the grain. After sampling, the sample is dried to constant weight. Each sampling, interval of 5 days, the first sampling after the third day of drought treatment. Drain every time, quit
