| 摘 要： | 以泗棉3号作为近期育成的棉花高产品种的典型代表，与苏棉5号进行比较，研究高产品种的源库流特点及其相互关系。其主要结果为高产品种具有较早的库形成能力，生殖生长势强，即在中期有较多的干物质进入生殖器官，同时幼铃(10日龄)应有较强的获得光合产物的能力。高温富照期有较高的成铃强度和库活性，叶源既要有较强的物质生产能力，还应将形成的产物尽快地输出。在生化方面，叶源具有较强的光系统PSI和较高的RuBPcase活性。

| Abstract: | The recently released high-yieldingcotton variety Simian3 was used as a typical rep-resentative and to be compared with the varietyof Sumian 5. The source-sink and their relationswere studied so as to offer some internal and ex-ternal reference indications for breeding new va-rieties. The main results acquired were as fol-lows: prolific varieties are possessed usually ofearlier capability of sink formation and strong
reproductive growth vigor, which means moredry matter may be absorbed into the reproduc-tive organs, additionally, juvenile buds (10 dayold buds) may be with relatively strong ability ofabsorbing photosynthetic products, and theproducts thus formed may be exported as quicklyas possible. On the biochemical respect, leafsource should be with relatively strong photo-system PSI and rather high RuBPcase activity. |
