摘要: Unrolling of sections from dark grown barley leaves (Hordeum vulgare L. cv. Klages) was stimulated by red irradiation. The unrolling started after a lag phase 6-8 h and completed 24 h. effect several keto amino acids on leaf compared with their coleoptile segment expansion growth. Of the substances tested δ-aminolevulinic acid had most inhibitive least Prolonged treatment caused strong inhibition but short tretment, stimulation occurred. only found if within Kinetin gibberellic could decrease inhibitory acid. A possible role for working as triggering substance is discussed.
