摘要: 试验设计了一套叶绿素荧光在线检测系统,通过MINIPAM荧光仪可以实时检测到植物叶绿素的荧光参数,并采用LED光源模拟不同的光照条件,测量了植物在不同条件下的荧光参数以及快速光响应曲线。检测系统通过232串口通信协议同上位机通信,利用WinControl软件实现数据的采集与保存。结果表明,适宜的光照可以大大促进植物PSⅡ的最大量子产量,从而提高农作物的产量,受环境胁迫的植物的光合作用受到明显的抑制。

Abstract: A set of online detection system for chlorophyll fluorescence was designed. The fluorescence intensity of chlorophyll was detected by MINIPAM fluorescence detector, and LED light source were used as different light conditions, fluorescence parameters and fast response curves of plants under different conditions were measured. Detection system through 232 serial communication protocol with the host computer communication, WinControl software was used to achieve data collection and preservation. Experimental results showed that the suitable light could greatly promote the photosynthesis of plants, and thus improve the yield of crops, and the photosynthesis of plants under the environmental stress was obviously inhibited.
