Effects of mesophyll water potential on photosynthesis in Gramineae plants: with special reference to phylogeny of subfamilies

TTTomoshiro TAKEDATashkent State Agrarian UniversityRFRyo FukiyamaKitasato University

Key Points

  • Photosynthetic rates increase with higher mesophyll water potential, revealing strong interdependent relationships.
  • The oxygen electrode method measured O2 evolution rates across various Gramineae species to establish links to water potential.
  • Diverse species from six Gramineae subfamilies provided comparative insights into the phylogenetic impacts on photosynthesis.
  • Findings underscore the necessity for further phylogenetic studies, particularly in understanding adaptation to water availability.

Abstract

We selected several species from six Gramineae subfamilies and examined relationships between the photosynthetic rate and mesophyll water potential (ΨL). We used the oxygen electrode method originally devised by Ishii et al. and modified by Ishihara et al. Namely, we used a liquid -phase oxygen electrode and measured the O2 evolution rate.
