概要

• 論文の詳細を見る

• When stratified sugar maple seeds were germinated at 5℃, cell division did not contribute to radicle emergence or to early growth of the embryonic axis. Putrescine, spermidine and spermine contents remained low throughout stratification, but following germination their levels rose gradually for several days and then entered a phase of rapid accumulation concurrent with initiation of rapid cell division. When inhibitors of putrescine and polyamine biosynthesis were applied to newly germinated seeds, levels of the amines and cell division were markedly reduced, but cell elongation, as evidenced by growth of hypocotyls, was not affected.
