    摘要:

    本试验采用植物种子水引发预处理技术,以采自青海海北州的垂穗披碱草种子为材料,研究水引发不同处理时长(10、20、30、40、50 min)对种子萌发和幼苗生长的影响。结果表明,种子发芽率、发芽势、发芽指数、活力指数和幼苗胚芽长、胚根长及干物质量在不同时长处理间存在差异,以水引发时长20~30 min处理显著高于其他处理(P<0.05),表明垂穗披碱草种子水引发处理的最适时长为20~30 min。本研究为有效解决实际生产中垂穗披碱草种子萌发率低、出苗不齐等问题提供理论依据和技术支撑。

    Abstract:

    In this experiment, the seed from Haibei of Qinghai was taken as the research material, hydro-priming pretreatment technology of plant seeds was adopted to study the effects of hydro-priming treatment of different durations(10, 20, 30, 40 and 50 min) on seed germination and seedling growth. The results showed that seed germination rate, germination potential, germination index, vigor index, seedling embryo length, radicle length and dry matter quality were different in different time treatment, hydro-priming time of 20~30 min was significantly higher than other treatments(P<0.05), hydro-priming treatment for 20~30 min was the optimal time. This study provides theoretical basis and technical support for solving the problems of low seed germination rate and uneven seedling growth in actual production.
