Portions of the shoot system from young light-grown pea (Pisum sativum L.) seedlings were excised and circumnutation studied using time-lapse cinematography. Removal of the youngest leaf or shoot tip as well as ringing the stem with 20 mM triiodobenzoic acid severely restricted circumnutation. Treating the stump of the excised leaf with lanolin containing 10(-4) M indole-3-acetic acid or replacing the leaf with an artificial aluminum leaf both partially restored circumnutation. When the leaf… CONTINUE READING
