摘要
研究和比较了八个不同类型的春小麦品种于物质积累运转及产量形成规律,结果表明不同品种春小麦的叶片、鞘、茎、穗部的干物质积累与运转是存在差异的,花前、花后干物质积累量与运转决定着小麦产量的高低,从而导致这8个小麦品种的最终产量存在差异。其中新春15号产量最高,其次为新春12号、新春26号、新春17号、新春6号、98-8、新春13号、y-20,且分别高出20.83%、24.38%、30.38%、32.60%、34.11%、34.75%和37.11%。通过对干物质变化动态和转运的进一步分析发现,强筋类春小麦相对于其他类型春小麦干物质积累较低,但品种间的差异同时存在。而中筋、中强筋、弱筋类春小麦之间没有明显的规律或规律性不强。
This research was carried out to compare the effects of accumulation and transformation of dry mater on the yield formation of different spring wheat varieties. The results showed that there was a difference in the accumulation and transformation of leaf, stem,spike of the different spring wheat varieties. The accumulation and transformation of dry matter both before and post anthesis period was the key factor that determines the wheat yield amount, so there was a difference in final yield amount of eight spring wheat varieties. The final yield amount of eight spring wheat varieties were Xinchunl5 〉 Xin Chunl2 〉 Xin Chun 26 〉 Xin Chun 17 〉 Xin Chun 6 〉 98 - 8 〉 Xin Chunl3 〉 y - 20.
