Abstract

Indoleacetic acid (1AA) brings about a striking alteration in the normal geotropic response in the seedlings of onion and several other species of Allium. The seedlings which are normally positively geotropic, become ageotropic. Besides IAA several other auxins like IBA, NAA and 2,4-D also showed a similar response. An anti-auxin like triiodobenzoic acid (TIBA) enhanced the auxin-effect instead of reversing it. A marked enhancement of the auxin-effect was also brought about when sucrose (in the culture medium) was replaced by L-arabinose which appeared to act synergistically with the auxin.
