Abstract

In agar cultures 1-naphthaleneacetic acid (NAA) reduced bud activity of quackgrass (Agropyron repens (L.) Beauv.) rhizomes, while indole-3-acetic acid (IAA) had little effect. Gibberellic acid (GA) acted antagonistically with NAA. Maleic hydrazide (MH) had less effect on bud activity than isopropyl N-phenylcarbamate (IPC), 2,3,6-trichlorophenylacetic acid (fenac), or phenoxy compounds at high rates. GA or its active metabolite was translocated throughout the plant. 2,3,5-Triiodobenzoic acid stimulated bud activity on intact rhizomes.
