Xiao-Ping LI author ONG Bee-Lian author text journal article 1997 Tolerance of gametophytes of Acrostichum aureum to NaCl and dehydration was investigated under controlled conditions following the changes in chlorophyll fluorescence parameters (Fv/Fm, qP, qN). Salt tolerance was increased by growing gametophytes in low concentrations of NaCl. However, such treatment could not increase the tolerance of gametophytes to dehydration. Under water stress, a decrease in photochemical quenching (qP) was accompanied by an increase in non-photochemical quenching (qN). Under salt stress, qP also decreased, but qN did not change significantly in salt-hardened gametophytes. chlorophyll fluorescence; dehydration; fern; NaCl; osmotic potential; salt stress 10.1023/A:1006851431516 https://ps.ueb.cas.cz/artkey/phs-199711-0003.php https://ps.ueb.cas.cz/artkey/phs-199711-0003.php continuing 34 11 21 30 1997 03003604 periodical academic journal
