Stimulation of bulb growth in onion (Allium cepa L.) by N,N-diethyl-N-(2-hydroxyethyl)glycine

  • J. S. Knypl
Original Papers


Both N,N-diethyl-N-(2-hydroxyethyl)glycine (DEHEG) and N,N-diethyl-2-oxomorpholinium chloride (DEOMC) in an optimal dosage of 4 × l0 μmoles per seedling initially accelerated then retarded leaf growth in onion, and doubled the yield of bulbs in field conditions. Gibberellin and auxin nullified the latter effect. It is concluded that DEHEG represents a physiologically active form of DEOMC.
