Abstract
The effects of ethylene, light and abscisic acid (ABA) on the germination of prematurely-harvested and mature Q. robur seeds were studied. There was evidence of active biosynthesis of ethylene, but not of ABA in seeds from both harvests. Addition of ABA, the ethylene precursor, 1-aminocyclopropane-1-carboxylic acid (ACC) or the ethylene-releasing compound Ethephon (E) to germination media and exposure to light individually inhibited germination and their effects were additive. The ethylene biosynthesis inhibitor aminoethoxyvinylglycine (AVG) tended to promote germination of premature seeds only.Keywords
