| description | The availability of commercially available portable photosynthesis systems has facilitated widespread photosynthetic research. Our study aimed to evaluate the reliability of a recently developed inexpensive portable photosynthesis system, Yaxin-1105, in measuring gas exchange in rice (<i>Oryza sativa</i> L.) leaves. Gas exchange parameters, including net photosynthetic rate (<i>A</i><sub>net</sub>), stomatal conductance (<i>g</i><sub>s</sub>), intercellular CO<sub>2</sub> concentration (<i>C</i><sub>i</sub>), and transpiration rate (<i>E</i>), were measured on 88 rice leaves across seven rice cultivars and three growth stages (panicle initiation, heading, and early ripening), using both Yaxin-1105 and LI-6400XT. There were significant difference between each gas exchange parameter at each growth stage measured by Yaxin-1105 and LI-6400XT, except <i>C</i><sub>i</sub> at the heading stage. Mean <i>A</i><sub>net</sub>, <i>g</i><sub>s</sub>, and <i>E</i> measured by Yaxin-1105 were 26–66% lower than those measured by LI-6400XT at panicle initiation, heading, and early ripening stages. Mean <i>C</i><sub>i</sub> measured by Yaxin-1105 was 13–22% higher than that measured by LI-6400XT at panicle initiation and early ripening stages. The coefficients of determination between each gas exchange parameter measured by Yaxin-1105 and by LI-6400XT at panicle initiation, heading, and early ripening stages ranged from only 0.0007 to 0.1889. These results indicate that the Yaxin-1105 is not a reliable tool for measuring gas exchange in rice leaves. |
