"百闻不如一见!" -- NMT视频资源介绍 [PDF]

open access: yes, 2023
非损伤微测技术(NMT)作为生命科学领域的关键核心技术,已帮助中国科研学者在包括Cell、Nature、Science 等在内的各类学术期刊上发表各类文献超过1200 篇,但由于NMT 目前依然属于普及度不高的新技术,初次接触NMT 的研究人员,需要花费较高地时间成本来收集NMT 相关资料,以了解并学习NMT 的使用。 为了能够让研究者们更系统、高效地学习NMT,我们汇总了国内NMT 领军企业旭月公司及超过1000 位的中国科研学者和工程技术人员,在近二十年的时间里总结出的应用经验和体系视频资源 ...

Variation in mycorrhizal communities and the level of mycoheterotrophy in grassland and Forest populations of Neottia ovata (Orchidaceae)

open access: yesFunctional Ecology, Volume 37, Issue 7, Page 1948-1961, July 2023., 2023
Read the free Plain Language Summary for this article on the Journal blog. Abstract Orchid mycorrhiza forms unique symbiotic associations between members of the Orchidaceae and multiple ecological guilds of fungi. Because orchids associate with a wide variety of fungi with different ecological functions, they represent an ideal study system to address ...

Environment regimes play an important role in structuring trait‐ and taxonomy‐based temporal beta diversity of riverine diatoms

open access: yesJournal of Ecology, Volume 110, Issue 6, Page 1442-1454, June 2022., 2022
Our study provides a new perspective into temporal beta diversity of daily riverine diatom communities. The results highlight the importance of taxonomic and functional temporal beta diversity and its decomposition, which is co‐driven by hydrology, nutrient and metal ions. We provide further evidence that environment regimes (e.g.

流溪河水库流域碳氮营养盐浓度的时空变化特征及其影响因素

open access: yesShuitu Baochi Xuebao, 2022
流溪河水库流域是亚热带典型的山地河源区,研究此流域的碳氮营养盐浓度时空变化特征及其影响因素对揭示亚热带流域生物地球化学循环与保障水资源供给具有重要意义。基于地形、气象、土地利用、土壤和实地采样获得的水质数据,采用相关分析及Elastic Net回归分析法,探讨了流溪河水库流域溪流碳氮营养盐浓度的时空变化特征及其影响因素。结果表明:(1)从时间上看,枯水期各采样点溪流碳氮营养盐浓度总体变化不大,但空间差异明显,其中NO3-与NH4+浓度具有强相关性。(2 ...

Potential harm of coastal sedimentary nutrient in inducing red tide(沿海沉积营养物质对引发赤潮的潜在影响)

open access: yesZhejiang Daxue xuebao. Lixue ban, 2004
从生物地球化学的角度阐述了引发赤潮的营养和环境控制因素,并在分析了赤潮藻的限制性营养元素(磷、氮、硅)和微量元素(铁、锰)环境地球化学行为的基础上,提出了沿海沉积营养元素的释放与赤潮之间的相关关系模式,同时指出了中国沿海近代沉积物中营养物的积累趋势及其对引发赤潮的潜在危害,这不仅为揭示赤潮发生机理开辟了新的研究方向,而且也为有效地防治赤潮危害提供了科学依据.

小麦氮素营养与籽粒灌浆期氮素转移的研究进展

open access: yesShuitu Baochi Xuebao, 2004
对小麦氮素营养与籽粒灌浆期氮素转移研究进展进行了综述。过去进行的大量研究结果表明,小麦籽粒最终累积的氮素有相当一部分来自于灌浆期间营养器官中氮素的再转移,来自营养器官氮(内源氮)与土壤中新吸收氮(外源氮)的比例基本上是1:2。因此,花后营养器官氮素营养水平是决定小麦籽粒产量、籽粒中氮素累积量和蛋白质含量的一个重要因素。灌浆期间营养器官氮素向籽粒发生转移的同时,常常伴随着叶片光合性能的下降和叶片的衰老。不同基因型品种在灌浆期的氮素转移程度不同,表现为随品种演替,旗叶、茎秆和叶鞘中氮素的输出率增加 ...

盐氮效应对棉花氮素分配、转运和利用效率的影响

open access: yesShuitu Baochi Xuebao, 2021
探究盐氮效应对棉花氮素动态积累、运转及利用效率的影响机制。以棉花“新陆中68号”为材料,设置土壤盐分含量为S1(2.5~3 g/kg)、S2(5~6 g/kg)和S3(8~9 g/kg),施氮量分别N1(105 kg/hm2)、N2(210 kg/hm2)、N3(315 kg/hm2)处理进行田间小区试验。通过Logistic生长函数模型对各器官生物量氮素累积进行拟合,以Vm(最高累积速率)和Δt(持续时间)为2个动态特征指标分析盐氮对棉花生物量氮素快速累积时间和速率的影响。结果表明,营养器官(根、茎 ...
