The hydroponic experiment was conducted to evaluate the genotypic differences of 31 wheat cultivars to high ammonium tolerance at seedling stage, in order to achieve suitable high ammonium tolerance genotype in wheat.The ammonium level of 5 mmol · L-1 was designed.With 5 mmol·L-1 single NO-3-N nutrient solution culture as the control.The results showed that the difference in response of different genotypes of wheat to elevated NH+4 is significant.

Background: A variety of common organophosphorus pesticides (OPs),were applied extensively for crop protection, such as dichlorvos (DDV), methyl parathion (MP),and so on.However, they have toxic effec
miR-397a has been known to play a key role in plant development and in stress response by regulating mRNAs that code for the LAC2 in Arabidopsis.In this study, we had verified that miR-397a was highly
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
Cadmium is a non-essential element for tobacco (Nicotiana tabacum cv.Xanthinc) growth, but easily absorbed.Cadmium ion can not only be remained in the tobacco, but has the obvious harm on its growth.T
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.
To investigate the effects of nitrate (NO3-), ammonium (NH4+) and themixture of NO3-and NH4+ on photosynthesis of wheat seedlings (Triticum aestivum L.) under water stress,hydroponic experiments with
Many adverse environmental conditions, including drought, high salinity, and freezing, induce stresses to plant cells.Extensive efforts have been made to the elucidation of sensory and signal transduc
Proline accumulation is an important mechanism for osmotic regulation under salt stress.In this study, we evaluated proline accumulation profiles in roots, stems and leaves of Jerusalem artichoke (Hel
Heat is a major factor limiting growth of C3 grass species.Elevated CO2 may mitigate the adverse effects of heat stress or enhance heat tolerance.The objective of this study was to determine metabolic
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.
