【摘要】

：

用含不同浓度(O、100、200、300,400和500 mmol·L-1)NaCl的Hoagland营养液及叶面喷施外源亚精胺(spermidine,Spd)处理毕氏海蓬子幼苗,研究外源Spd对NaCl胁迫下海蓬子体内游离态、结合态和束缚态3种形态多胺含量的影响。结果表明,不同浓度盐处理条件下3种形态腐胺(putrescine,Put)含量的变化一致,均为先降低后升高。游离态Spd含量一直呈上升

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.

小麦幼苗生长对不同铵浓度的响应特征及生理机制

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.
