现代植物生理生态学的发展是和测定仪器的进步同步进行的。小型轻便、智能、性能优良和高自动化程度是植物生理生态学仪器发展的必然趋势。该文以光合生理生态学的仪器为例，概述了该领域测定仪器的发展趋势及对学科发展的重要作用,并讨论了控制实验和实验设计中的假重复问题。
Development of modern plant ecophysiology is synchronous with progress in instrumentation, with higher quality instruments becoming more portable, capable and automatic. The progress of instrumentation and its important effects on the development of ecophysiology of photosynthesis are described, and problems with controlled experiments and pseudo-replication in experimental design are discussed.
