摘要:
为明确干旱胁迫对青稞种子萌发期的影响,研究萌发期形态指标与抗旱性关系,构建抗旱性评价方法。选用70份青稞为材料,设置了干旱胁迫(19.2%PEG-6000)、对照(纯水)2组试验,试验过程中每日观察记录种子生长情况,第7天测量芽长(BL)、根长(RL)、芽鲜质量(BFW)、芽干质量(BDW)、根鲜质量(RFW)和根干质量(RDW)等指标。通过干旱胁迫条件下青稞各指标的变异分析,可看出干旱胁迫下青稞种子的发芽势(GE)、发芽率(GR)、发芽指数(GI)、芽长、主胚根长、芽鲜质量、芽干质量、根鲜质量和根干质量均受到抑制作用,其中受干旱影响最大的指标为根长,在干旱胁迫下根长平均值较对照减少9.94 cm,变异系数下降38.65%;对以上指标进行箱线图直观分析,在PEG胁迫下GE、GR、GI数值都将会降低,其中GI在CK处理下结果明显大于干旱处理的数值,根部性状和幼苗特性在对照条件下与干旱处理下二者数据相差较大,均受到一定抑制作用;以上9个指标的相对值通过隶属函数综合评价法计算出平均隶属函数值,隶属函数值平均值越大,抗旱性越强,计算得出排名靠前的材料有藏青311、ZDM4953、喜拉10号和北青5号,反之,抗旱性越弱,抗旱性较弱材料有藏青80、舍么、农家品种1和哲鲁玛;将70份青稞材料的隶属函数综合评价值通过聚类分析可分为3大类,第1类为高度抗旱材料共18份,第2类中度抗旱共28份材料,第3类敏感材料共24份。结果表明,发芽指数、根部性状和幼苗特性均可作为青稞萌发期抗旱性鉴定的可靠指标。本研究结果可为青稞抗旱材料的选育提供理论依据。
