- 摘要:
- 研究表明, 遮光对大豆的产量及品质有一定的影响作用。随着遮光时数的增多, 也就是日照时数的减少, 大豆子粒的蛋白质含量、脂肪含量、蛋脂总量及产量都有显著的变化。但品种的遗传特性对化学品质及产量的影响大于遮光的影响。光照长度的影响作用不仅涉及光合时间而且与光周期本身的机制有关。遮光对大豆子粒产量及品质影响大小顺序为:产量(F =5 .93* *)> 蛋白质(F =3 .16*)>脂肪(F =2 .61)>蛋脂总量(F =0 .64)。
- Abstract:
- Shading durat ion had some ef fect on the yield and quality of soybean through analysis.Along w iththe increase of shading duration , and the decrease of sunshine duration , the content of pro tein w as rising .Whenthe sunshine duration w as 12 hours , the content of protein reached the maximum value , and then dropped .Thisverified the previous view points of sho rt -time sunshine helpful to the fo rming of the protein .The changes of fatcontent w ere opposite to that of the pro tein .With the shortening of the sunshine duration , the fat content decreased.This show ed that the content of pro tein and fat had the negative correlation .The circumstance that wasadvantageous to the forming of the pro tein w as disadvantageous to the forming of the fat .Wi th the increasing ofthe shading duration and the shortening of the sunshine hours , the plant height , the number of pods and seedsper pod decreased w hich made the yield of soybean dropped .The order of shading on the yield and quality ofsoybean w as y ield (F =5 .93**)> the content of protein (F =3 .16*)>the content of fat (F =2 .61)>the totalcontent of protein and fat (F =0 .64).
