| 摘 要： | 谷子蛋白质产量与子粒产量密切相关，r＝0．9717**。不同播种期中，以5月5日播种的谷子子粒产量和蛋白质产量最高，分别达到63．21±11．66和7．91±1．45g/盆，比4月15日早播的分别增产25．59％和27．4％，比5月25日晚播的分别增产11．5％和20．4％。随着播种期的推迟，谷子蛋白质的各种氨基酸含量有规律地降低，推迟到5月下旬以后播种，下降幅度更大，与5月5日播种的相比，氨基酸总量减少14．5％～23．5％，EAA总量降低14．1％～24．6％，EAAI下降15．22％～25．78％。以赖氨酸和蛋＋胱氨酸减少最多，CS分别仅0．317～0．241和0．461～0．469。其次，苏氨酸、异亮氨酸和缬氨酸减少也较多，CS只有0．588～0．755。

Effects of Seeding Date on Protein and Amino Acid in Foxtail Millet |
| |
| Abstract: | There is a positive correlation between protein yield and grain yield in foxtail millet,r =0. 9717. The grain yield and the protein yield are different with the various seeding date. The highest is on May 5, they are 63.21 ±11 .66g/pot and 7.91 ±1 .45g/pot respectively. They are 25.59% and27.40% higher than those which seeding date is on April 15 and 11. 5% and 20. 4% higher than on May 25. The Amino acid content of protein in foxtail millet regularly decreases with the postopnement of seeding. It is the lowest after the last ten-day of May. Compared with that on May 5, total amount ofamino acid decreases 14 .5% ～23. 5%, EAA decreases 14. 1 % ～24 .6% and EAAI decreases 15. 22%～25. 78%, in which lysine and methionine + cystine decrease seriously, CS of them are only 0. 317～ 0. 241 and 0 .461～0. 469 respectively, and thrconine, isoleucine and valine also decrease, CS of themare only 0. 588～0. 755. |
