摘  要：
【目的】筛选出萌发期抗旱性较强的黄麻品种,并建立黄麻萌发期抗旱性评价体系。【方法】在聚乙二醇(PEG)(PEG6000)模拟干旱胁迫条件下,采用培养皿法对11个黄麻种子进行发芽试验,PEG设6个浓度处理,分别为(A)5%、(B)10%、(C)15%、(D)20%、(E)25%,测定种子发芽各项指标。【结果】随着PEG处理浓度的升高,黄麻种子的相对发芽势、相对发芽率、相对发芽指数、相对活力指数、相对胚根长、相对胚芽长均呈下降趋势;低浓度PEG(5%)处理促进黄麻种子胚根的生长,而较高浓度PEG(10%～25%)处理则抑制其胚根生长;圆果种黄麻中以圆09-30、圆09-35发芽最好,圆3号最差;长果种黄麻中以长09-41、长09-40发芽最好,长09-1最差。【结论】5%～10%的PEG可作为区分长果种黄麻萌发期抗旱性差异的适宜浓度,15%～20%的PEG可作为区分圆果种黄麻萌发期抗旱性差异的理想浓度。

摘  要：
[Objective]The present experiment was conducted to screen the different varieties of Corchorus capsularis L.for drought resistance in germination period,and to establish the evaluation system of drought resistance.[Method]The seeds of eleven different varieties of Corchorus capsularis L.were germinated in petri dishes under different concentrations(5,10,15,20 and 25%) of polyethylene glycol(PEG6000).Seed germination indices,viz.,relative germination rate(RGR),relative germination energy(REG),relative germination index(RGI),relative vigor index(RVI),relative radicle length(RRL),relative embryo length(REL),were determined.[Result]It was observed that RGR,REG,RGI,RVI,RRL and REL in seeds of all the varieties of Corchorus capsularis L.decreased with the increasing concentration of PEG.However,low concentration of PEG(5%) promoted RRL in Corchorus capsularis L.seeds,and 10-25% PEG concentration inhibited its REL.Among the varieties of C.capsularis,Yuan 09-30 and Yuan 09-35 recorded best RGR,while Yuan 3 showed the worst.Out of C.olitorius varieties,Chang 09-41 and Chang 09-40 recorded best RGR,while Chang 09-1 showed the worst.[Conclusion]The concentrations of PEG ranging from 5-10% and 15-20% were found the best in terms of differentiating in varieties of C.olitorius and C.capsularis,respectively,for drought resistance during the germination period.
