NEW Webinar 莴苣叶片光合效率和气体交换参数对温度和光强的响应

美***PP SYSTEMS公司将于美***东部时间2024年2月7日上午11点邀请美***乔治亚大学Suyun Nam为全球用户做题为“Photosynthetic efficiency and leaf gas exchange responses of lettuce to temperature and light intensities”的学术报告。

As well as light intensity, temperature conditions significantly affect photosynthetic efficiency, both conditions should be considered for optimal artificial lighting control. In this webinar, the effects of temperature and light intensity on photosynthetic efficiency and leaf gas exchange in lettuce plants were investigated. The photosynthetic acclimation process was also evaluated. Leaf gas exchange parameters and rapid A/Ci response curves with a high-speed CO2 ramping technique were measured using the CIRAS-3 Portable Photosynthesis System. The results indicate that plants use light less efficiently depending on the combinations of temperature and light intensity conditions, resulting in lower leaf gas exchange and biomass accumulation. Additionally, the increasing quantum yield of photosystem II (φPSII) over time under high light intensity suggests that plants can acclimate and improve their photosynthetic efficiency.
