摘要
为进一步挖掘大麦(Hordeum vulgare)地方品种耐低氮性潜能,从前期研究0.50 mmol·L~(-1) NH_4NO_3低氮胁迫筛选到的5份耐低氮大麦地方品种中随机挑选了3个,通过两个氮素浓度更低的低氮胁迫(分别为0.24和0.10mmol·L~(-1) NH_4NO_3)对其进行耐低氮鉴定。结果发现,大麦地方品种‘上海有芒大麦’在这两个低氮胁迫下都表现出较好的耐低氮性,‘六柱头紫大麦’仅在0.24 mmol·L~(-1) NH_4NO_3下耐低氮性较好,而‘宝山老脱须’在这两个低氮胁迫下耐低氮性都比较差。变异系数分析进一步验证了干重性状比较适合作为大麦耐低氮筛选指标,而株高不太适合。本研究又进一步探索了氮素相关生理性状作为大麦耐低氮评价的可行性,并且讨论了在低氮胁迫下氮素吸收和利用相关性状对大麦耐低氮的重要性。
To further explore the potential of low nitrogen tolerance of barley(Hordeum vulgare)landraces,three of the five barley landraces with low nitrogen tolerance under 0.50 mmol·L~(-1) NH_4NO_3 treatment were randomly selected for identification of low nitrogen tolerance under two lower nitrogen stresses(0.24 and 0.10mmol·L~(-1) NH_4NO_3).The results show that the barley landrace of‘Shanghai Youmang Damai’was tolerant to both of the low nitrogen stresses,while‘Liuzhutou Zidamai’was only tolerant to low nitrogen stress of 0.24mmol·L~(-1) NH_4NO_3,and ‘Boshan Laotuoxu’ was not tolerant to the two lower nitrogen stresses.Coefficient of variation analysis suggests that dry weight related traits were more suitable as screening indices for low nitrogen tolerance,while the trait of plant height was not.In addition,this study further explores the possibility of low nitrogen tolerance identification by physiological traits related nitrogen uptake or utilization,and discusses the importance of nitrogen uptake or utilization on low nitrogen tolerance.
