Photosynthetic apparatus activity in relation to high and low contents of cell wall-bound phenolics in triticale under drought stress Hura K. author Ostrowska A. author Dziurka K. author Hura T. author text journal article 2017 Cell wall-bound phenolics (CWP) play an important role in the mechanisms of plant acclimation to soil drought. The study involved CWP analyses in 50 strains and 50 doubled haploid (DH) lines of winter triticale exposed to drought at their vegetative and generative stages. CWP in the plants experiencing drought at the generative stage positively correlated with their leaf water contents. The strains and DH lines characterized by high content of CWP showed higher leaf water content and higher activity of photosynthetic apparatus when exposed to drought at the generative stage compared to the strains and DH lines with the low CWP content. Furthermore, when drought subsided at the generative stage, the strains and DH lines richer in CWP demonstrated higher regeneration potential and their grain yield loss was smaller. chlorophyll fluorescence; doubled haploids; leaf water content; strains; × Triticosecale Witt.; yield 10.1007/s11099-017-0687-2 https://ps.ueb.cas.cz/artkey/phs-201704-0017.php https://ps.ueb.cas.cz/artkey/phs-201704-0017.php Photosynthetica continuing 55 4 698 704 2017 03003604 periodical academic journal
