The effect of submergence on germination and some aspects of the respiratory metabolism of cucumis sativus l. seeds


, : The effect of submergence on germination and some aspects of the respiratory metabolism of cucumis sativus l. seeds. Plant Science (Shannon) 63(1): 7-14

In contrast to the seeds of other Cucurbitaceae species, cucumber seeds are able to germinate while completely submerged in water. Alcohol dehydrogenase activities of normoxic (control) and submerged seeds were similar. However, the ethanol content of submerged seeds was substantially higher than that of control seeds. Isocitrate lyase activity of the control seeds increased following radical protrusion while no increase in activity was observed in the submerged seeds after radicle protrusion. The rate of labelled carbon dioxide release from [1-14C]glucose, [6-14C]glucose and [2-14C]acetate was lower in submerged than in control seeds. The oxygen uptake of seeds after 16 h of submersion was much lower than that of the control.
