1种子顽拗性:最新评价(英文)显示文摘根据种子的脱水行为 ,可以把种子分为正常性、顽拗性和中间性种子三种类型。种子脱水耐性和脱水敏感性的鉴定是制定种子的贮藏策略和物种基因资源长期保存的依据。除了物种的内在特性外 ,种子的发育状态、脱水速率、脱水时和重新水合时的环境是影响种子脱水耐性的重要因子。种子的存活率、电解质渗漏速率和存活种子的萌发生长速率是衡量种子脱水耐性的良好的综合参数。种子的脱水耐性是一种数量性状 ,用“临界含水量”的概念来判断是不正确的 ,且在评价种子顽拗性中引起了一些混乱。宋松泉 Patricia BERJAK Norman PAMMENTER Tobias M.NTULI 傅家瑞 2003Acta Botanica Sinica2003,45,6:4
2Increased Drying Rate Lowers the Critical Water Content for Survival in Embryonic Axes of English Oak (Quercus robur L.) Seeds显示文摘潜力到 cryopreserve 胚胎的轴干燥敏感(不顺从) 种子被损坏在为这损害的低温度幸存,而是基础必要的干燥期间限制并且怎么减少它很好没被理解。在生存能力,呼吸新陈代谢和免费调停激进分子的过程上弄干率的效果因此在 Quercus robur L 的脱水期间被调查。胚胎的轴。生存能力,由萌芽并且 tetrazolium 染色的证据估计了,在 0.27 和 0.8 g/g 显示出锋利的衰落在期间快速(< 12 h ) 或慢(3 d ) 脱水分别地。快速的脱水因此为幸存降低了批评的水内容。在任何给定的水内容,快速的脱水与处理酶, superoxide dismutase,过氧化氢酶和谷胱甘肽 reductase 和 hydroperoxide 和膜损坏的底层的自由激进分子的更高的活动被联系。快速的脱水也在 phosphofructokinase 活动并且在菸碱 dinucleotide 的氧化形式的层次与更低的 malate 脱氢酶活动,和减少的衰落被联系。变老可能在慢脱水期间贡献了增加的损坏,自从生存能力在 3 d 以后甚至在含水的存储衰退了。介绍的结果与减少损坏源于干燥的累积的快速的脱水一致导致的水底的有害反应。Tobias M.Ntuli William E.Finch-Savage Patricia Berjak Norman W.Pammenter 2011Journal of Integrative Plant Biology2011,53,4:2
3豌豆种子吸胀过程中脱水耐性变化的时间模式(英文)显示文摘研究了豌豆种子吸胀过程中脱水耐性的变化模式。种子在吸胀初期迅速吸收水分,然后缓慢吸收直到平台期。电解质渗漏速率在吸胀初期增加直到11h,然后随着吸胀下降。在吸胀过程中,种子的萌发率逐渐增加,种子和胚轴的脱水耐性逐渐丧失,10%和50%的种子和胚轴被脱水致死的含水量明显增加。赤霉素和脱落酸处理改变豌豆种子的萌发特性,提高胚轴的脱水耐性。研究结果表明,吸胀的豌豆种子脱水耐性的丧失是一种数量性状,正常性种子吸胀后脱水耐性的变化能够作为种子顽拗性研究的模式系统。宋松泉 Patricia BERJAK Norman W.PAMMENTER 2009云南植物研究2009,31,3:2
