摘要
壮苗的形成对提高作物产量具有重要意义。为探索玉米自交系壮苗的形成基础，本试验研究了在玉米自交系幼苗形成过程中，影响种子贮藏物质转化和分配的因素。将3种玉米自交系作为试验材料，探究种子在幼苗建成过程中，种子大小、种子活力、光照时长、温度、沙床含水量和沙床盐浓度等因素对种子贮藏物质转化和分配的影响。研究结果表明，小粒种子的物质利用率比大粒种子高3.69-17.71% 。适当延长光照时间有利于形成壮苗。低温、干旱和盐胁迫等因素在一定程度上降低了种子贮藏物质利用率，提高了根苗比。以上研究结果可用于指导玉米自交系材料苗期的田间管理，对于改良玉米种质，提高种子贮藏物质利用率，形成壮苗有着重要意义。
Abstract Strong seedlings are essential for high yield. To explore the foundation of strong seedlings, we investigated various factors influencing the conversion and distribution of seed storage reserves during seedling establishment in maize inbred lines. Three maize inbred lines were used to explore the effects of seed size, seed vigor, illumination duration, temperature, water content, and salt concentration of the seedling medium on the utilization of seed storage reserves during seedling establishment. The results showed that the conversion rate of small seeds was 3.69 to 17.71% higher than that of large seeds. Moreover, prolonged illumination time was conducive to the formation of strong seedlings. However, low temperature, drought stress and salt stress reduced the conversion rate of seed storage reserves and increased the root/shoot ratio. These results could be used to guide field management during seedling emergence and develop improved germplasm with a high conversion rate of seed storage reserves.
