One of the prime precursor for ethylene synthesis - L-methionine and the inhibitor of 1-aminocyclopropane-1-carboxylic acid oxidase (ACO) - Co2+- were tested for their effects on sex expression and development of Anemia phyllitidis fern gametophytes. Five concentrations of both chemicals (0, 10, 25, 50, 100 μM) were analysed with reference to antheridia and archegonia formation, number and size of...
In Schizaeaceae ferns, including Anemia phyllitidis, formation of antheridia is known to be induced by exogenously applied gibberellic acid. Also present studies show that GA₃ (10⁻⁵ mol·dm⁻³) modifies the development of gametophytes of Anemia phyllitidis. Simultaneously with formation of antheridia, they exhibit lower number of cells but only slightly lowered profile areas and lengths of prothalli...
