【摘要】

：

目前酸沉降污染严重,酸沉降影响酸性土壤养分供应和转化,而氮磷矿化速率决定了土壤中用于植物生长的氮素、磷素的可利用性,因此把握酸沉降对土壤矿化的影响,对明确茶树养分循环规律和可持续经营具有重要意义.本实验选择江西典型丘陵红壤茶园(20年生)开展原位模拟酸沉降加重试验,进行对照(自来水)、pH4.5、pH3.5、pH2.5四种喷酸处理,15天一次,每次相当于降雨2mm.

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.

外源亚精胺对盐胁迫下毕氏海蓬子体内多胺含量的影响

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

水分胁迫对不同抗旱性燕麦品种叶片叶绿素荧光动力学参数的影响

燕麦是我国北方半干旱地区重要的粮饲兼用作物，其生长期间的干旱胁迫是影响其高产和稳产的重要因素。本研究通过在不同生育时期不同水分胁迫下对抗旱性不同的燕麦品种叶片叶绿素荧光动力学参数的研究，了解不同抗旱性燕麦在不同生育时期水分胁迫下光合生理响应差异，为燕麦高产稳产栽培和抗旱品种选育提供理论依据。
