2024-02-2085LI-COR Connect 2023 研讨会合影
2023年11月6日至9日,LI-COR Connect 2023 研讨会在美国乔治亚州亚特兰大市成功举办。在这为期四天的会议中,众多学者齐聚一堂,共同学习、交流,并展示了各自的研究成果。同时,LI-COR的科学家和工程师们还分享了仪器的研发进展、实验操作以及数据分析等内容。这次盛会,不仅为参会者们提供了一个学术交流平台,也为推动植物学、农学、大气科学、环境科学、生态学等学科的发展起到了积极作用。
研讨会主题
本次研讨会涉及多个主题:温室气体碳通量、植物光合生理、日光诱导叶绿素荧光、土壤碳循环、水生藻类、水生植物光合固碳等。
叶片水平气体交换和叶绿素荧光测量基础理论
叶片水平气体交换的测量(净同化速率、蒸腾速率、气孔导度、叶绿素a荧光)在植物生理学研究中非常重要,相关的测量技术也已经得到了学术界的充分验证,并成功整合到了现有的测量仪器中。然而,为了确保取得高质量的数据,需要研究人员对基础植物生理学过程和测量技术本身有深入的理解。
本次研讨会,研究者们介绍了叶片水平气体交换和叶绿素荧光测量背后的基本原理,重点关注基本假设和Z佳测量实践。
光响应曲线与数据拟合
通过对植物叶片光响应曲线进行测量,可以分析植物光合作用的光化学过程以及光能利用能力。研究者们探讨了光响应曲线的测量技术,并使用R语言进行了曲线拟合,获取了相关参数的估算结果,如Asat、Rd、表观量子产率等。
CO2响应曲线和数据拟合
通过对CO2响应曲线进行测量,可以揭示植物光化学过程和限制因素。在本次研讨会中,研究者们使用稳态和非稳态两种方法测量了CO2响应曲线,使用R语言对测量数据进行了拟合,并进一步求算出了Vcmax和Jmax等关键的光合参数。
叶片水平气体交换和碳稳定同位素测量
CO2同位素异构体与叶片尺度碳同化速率的同步在线测量,为追踪CO2的扩散路径提供了有力工具,使研究者们能够估算叶肉导度和叶绿体CO2浓度。在过去,这种同步测量系统只能在实验室内使用。然而,激光测量技术不断发展,全新的便携式CO2同位素气体分析仪研发成功了,研究者们现在有能力组建出更加方便的测量系统,从而实现了在野外就能对植物样品直接进行测量的目标。
针叶/狭叶的气孔导度测量
本主题聚焦针叶/狭叶气孔导度测量技术方面的进展。该主题深入探讨了在测量针叶和狭叶气孔导度时可能会面临的问题,分享了成功的测量经验和方法,并展示了松树叶片气孔导度的实测数据。
藻类悬浮液及其他液体样品的气体交换测量
研究者们探讨了如何将稳态气体交换测量技术应用于对液体样品的测量。研讨内容包括:藻类悬浮液体样品的测量实例;对液体样品进行气体交换测量时需要考虑的问题。
学术墙报
学术墙报也是本次会议交流的重点,共计有20余幅学术海报参展。研究内容包括植物光合生理学、温室气体循环、土壤温室气体排放、农学等领域的Z新研究成果。
