| Abstract: | Seedlings of Lycopersicon esculentum Mill. cv Rutgers emit a pulse of ethylene during the first 2 to 4 minutes following horizontal placement. Because this burst appears too rapid and brief to be mediated by increase in net activity of 1-aminocyclopropane-1-carboxylic acid synthase, it might result from accelerated transformation of vacuolar 1-aminocyclopropane-1-carboxylic acid to ethylene. |
