摘要: |
研究结果表明:品种对铃重影响作用表现为中早熟品种大于中熟品种,品种间差异随育苗期延后而增大。中早熟品种棉纤维发育早于中熟品种。品种对棉籽(仁)脂肪累积作用表现为中早熟品种优于中熟品种,而蛋白质累积则相反。棉仁棕榈酸、油酸、硬脂酸含量变化品种间差异较小,豆蔻酸和亚油酸变化趋势相反,品种间存在差异;品种对棉仁氨基酸累积的作用表现为中熟品种优于中早熟品种。3∶1式移栽棉品种选择受育苗期影响很大,早育苗时可选用中熟品种。 |

Effect of Varieties on the Cotton Boll Developmentof the Seedling Transplanting Cotton with 3∶1Cotton-Wheat Double Cropping Model |
|
Abstract: |
The results showed that the earlier-middle maturity cotton boll weight
was heavier than the middle maturitys, and the difference increased as postponing the
seedling period.Fiber development difference among varieties showed the law that earlier-middle maturity varieties were much earlier than the middles.As to the effect of varieties on fat accumulation in cotton seed, the earlier-middle maturity varieties were more
sentisive than the middles, but the accumulation of protein was just the contrary. The
effect of varieties on the content change of palmitic acid, oleic acid and sterne acid was
small, but it was opposite to the change of cardman acid and linoleic acid contents.The
middle maturity variety took advantage over the earlier-middle maturity variety in cotton
seed amino acid accumulation. Because the variety selection under the seedling transplanting method with 3∶1 model was always affected by the condition of seedling period, the middle maturity varieties should be chosen as seedling earlier. |
