小麦幼苗生长对不同铵浓度的响应特征及生理机制

来源 :2013全国植物生物学大会 | 被引量 : 0次 | 上传用户：JK0803_gengjixiang

【摘 要】

：

本研究利用水培法探讨了不同浓度NH：营养对小麦品种扬麦13苗期生长的影响及生理机制.试验设6个铵浓度水平(分别为1、2.5、5、7.5、10,15 mmol· L-1).用5mmol·L-1单一NO-3-N营养液培养为对照,处理14 d(四叶一心)后取样测定.结果表明,当铵浓度高于5 mmol· L-1时,随着NH+4浓度增高,株高和植株叶面积降低并低于对照.

水稻盐胁迫响应蛋白Os REM1的生物信息学分析

Remorin蛋白是一类新发现的与质膜/脂筏相联的植物专一性蛋白家族，可以响应植物防御及生长发育基因的激活而被磷酸化，可能参与了植物的多种信号转导途径，诸如盐胁迫、干旱胁迫和抗病信号途径等.Os REM1为进行盐胁迫水稻根尖质膜蛋白质组学研究中新发现的一个remorin蛋白，其表达受盐胁迫诱导.为进一步探明Os REM1对干旱、高盐等非生物逆境的应答机制，并为制备具有较强抗逆能力的转基因水稻奠定基

水分胁迫下硝态氮营养提高了苗期小麦的光合速率

冬小麦在苗期经常遭遇降水贫乏，使幼苗的光合作用和生长受到抑制，最终影响物质和能量的积累.本文通过15％ (m/v) PEG-6000(-0.24 Mpa)模拟干旱的水培试验研究了硝态氮(NO3-)、铵态氮(NH4+)和铵硝混合态氮对冬小麦望水白的光合作用的影响，以期为耐旱品种选育和改良提供理论依据.试验于温室进行，幼苗分别用3种不同氮素形态的营养液培养，五叶期进行干旱处理5d.
