| 1 | 种子引发对小麦抗盐及抗旱特性影响综述显示文摘小麦是我国北方重要粮食作物,在农业生产中经常受到干旱和盐分胁迫影响,造成减产。种子引发是在种子萌发前用天然或人工合成试剂对种子进行处理,从而提高植物抗逆性的一种简单而有效的方法。在干旱或高盐条件下,利用引发剂对小麦种子引发后,种子萌发提前,幼苗生长发育代谢增强,抗逆境相关生理指标提升,作物抗旱耐盐能力增强,最终产量及质量得到提高。本文阐述了水、有机物、植物激素、生物活性物质、生物、氧化物、无机信号物质等不同种类引发剂对小麦种子引发的作用机理和效果。并总结了种子引发的主要作用机制,如:减少植株对Na^+的吸收,增加对K^+、Ca^(2+)的吸收,减少盐分对生长造成的阻碍;促进可溶性蛋白和可溶性糖等渗透调节物质的合成和积累,细胞内维持高渗透压,有利于根系吸水;诱使胁迫条件下细胞内超氧化物歧化酶、过氧化物酶、过氧化氢酶、抗坏血酸过氧化物酶等抗氧化酶的合成增多、活性增强,有效清除活性氧,维持细胞内氧平衡;调节植物内源激素合成与运输从而使激素水平处于更加适应胁迫条件的平衡状态等。并讨论了引发剂与植物逆境生理研究之间相互补充、相互促进的关系,展望了种子引发在农业方面的发展及应用前景。 | 谢娟娜 路杨 房琴 张喜英 | 2016 | 中国生态农业学报2016，24，8： | 16 |
| 2 | Seed Treatment with Auxins Modulates Growth and Ion Partitioning in Salt-stressed Wheat Plants显示文摘实验被执行决定有植物生长素(吲哚醋酸( IAA ),吲哚基丁酸( IBA ),或他们的先锋 tryptophane ( Trp ))的不同集中( 100,150 ,和 200 mg/L )的种子 priming 是否能在水杨酸和离子集中改变咸度 inducedperturbances 并且,因此,在小麦( Triticum aestivum L.)的生长栽培变种, namelyM.H.-97 (盐偏狭)并且 lnqlab-91 (盐容忍)。告知并且非告知的种子在一个生长房间里,以及在与 15 dS/m NaCI 咸度对待的一块地里在 Petridishes 被播种。除了 IBA,所有 priming 代理人在两栽培变种增加了最后的发芽率。当时,栽培变种从对待 Trp 的种子提起了的任何一个的幼苗有更大的干燥生物资源在盐应力下面。内场实验, Trp priming 在调停是更有效的不管栽培变种,谷物产量的增加在盐下面强调。Trp 的 alleviatory 效果被发现在根和随后的 translocation 与 Na^+ 的减少的举起被联系到射击,以及增加了在强调 ofsalt 的小麦种的根 Ca^(2+) 划分。当时,从对待 Trp 、对待 lAA 的种子提起的两栽培变种的植物在他们的叶子积累了免费水杨酸在盐应力下面。总的来说,当时,在小麦植物的萌芽和 thesubsequentgrowth 的 Trp 整洁导致改进能与离子动态平衡有关在盐应力下面。在在盐的条件下面的更好的生长强调的 Trp 整洁导致的水杨酸的 Thepossible 参与被讨论。 | Muhammad lqbal Muhammad Ashraf | 2007 | Journal of Integrative Plant Biology2007，49，7： | 8 |
| 3 | Quantitative Analysis of Cytokinins in Plants by High Performance Liquid Chromatography:Electronspray Ionization Ion Trap Mass Spectrometry显示文摘The present paper introduces a highly sensitive and selective method for simultaneous quantification of 12 cytokinins(free form and their conjugates).The method includes a protocol of extraction with methanol/water/formic acid(15/4/1,v/v/v) to the micro-scale samples,pre-purification with solid phase extraction(SPE) cartridges of the extracts,separation with a high performance liquid chromatography(HPLC) and detection by an electrospray ionization ion trap mass spectrometry(ESI-Ion trap-MS) system in a consecutive ion monitoring(CRM) mode at the three stage fragmentation of mass spectrometry(MS 3).The lowest detection level of the cytokinins of the method reaches 0.1-2.0 pg with a very wide range of linear regression from 1-512 pg,at the coefficient factors of 0.98-0.99.The feasibility of this method has been proven in the application of the method to the analysis of the trace-amount contents of cytokinins in the micro-scale samples of various types of plant materials,such as aerial parts of rice and poplar leaves etc.12 endogenous cytokinins had been identified and quantified in the plant tissues,with an acceptable relatively higher recovery rate from 40% to 70%. | Weiqi Chen Ying Gai Shichang Liu Renxiao Wang Xiangning Jiang | 2010 | Journal of Integrative Plant Biology2010，52，10： | 4 |
| 4 | Salinity Stress in Wheat:Effects,Mechanisms and Management Strategies显示文摘Salinity stress is a major threat to global food production and its intensity is continuously increasing because of anthropogenic activities.Wheat is a staple food and a source of carbohydrates and calories for the majority of people across the globe.However,wheat productivity is adversely affected by salt stress,which is associated with a reduction in germination,growth,altered reproductive behavior and enzymatic activity,disrupted photosynthesis,hormonal imbalance,oxidative stress,and yield reductions.Thus,a better understanding of wheat(plant)behavior to salinity stress has essential implications to devise counter and alleviation measures to cope with salt stress.Different approaches including the selection of suitable cultivars,conventional breeding,and molecular techniques can be used for facing salt stress tolerance.However,these techniques are tedious,costly,and labor-intensive.Management practices are still helpful to improve the wheat performance under salinity stress.Use of arbuscular mycorrhizal fungi,plant growth-promoting rhizobacteria,and exogenous application of phytohormones,seed priming,and nutrient management are important tools to improve wheat performance under salinity stress.In this paper,we discussed the effect of salinity stress on the wheat crop,possible mechanisms to deal with salinity stress,and management options to improve wheat performance under salinity conditions. | Mahmoud F.Seleiman Muhammad Talha Aslam Bushra Ahmed Alhammad MuhammadUmair Hassan Rizwan Maqbool Muhammad Umer Chattha Imran Khan Harun Ireri Gitari Omer S.Uslu Rana Roy Martin Leonardo Battaglia | 2022 | Phyton-International Journal of Experimental Botany2022，91，4： | 1 |
