摘要: 尿囊素(All)溶液浸种对玉米生长影响的研究结果表明,All浓度为10-4~10-8mol/L时,能提高玉米种子活力和萌发系数,有利于玉米壮苗早发;能促进根系生长,提高根系活力,增强根系对养分的吸收能力;增大穗部叶面积,叶绿素含量和光合速度,有利于于物质的累积和产量的提高。

关键词: 玉米, 种子活力, 尿囊素, 净光合速率, 干物质累积, 产量

Abstract: The effects of All on maize growth were investigated after maize seeds were soaked in All.The results showed, All at concentration 10-4~10-8mol/L could raise vitality of maize seeds, germination coefficient ensure a strong growth of seedling and early development of root, enhance vitality of root system, increase mutrierit assimilation of root, enlarge the leaf area, raise chlorophyl content and net rate of photosynthesis, bene improve accumulation of dry-matters, therefore raise maize yield.

Key words: Maize, Vitality of seeds, Allantoin, Net rate of photosynthesis, Accumulation of dry matters, Yield
