Does the Induction of Flowering by Photoperiod Change the Polarity or Other Characteristics of Indole-3-acetic Acid Transport in Petioles for the Short Day Plant, Xanthium?


To test the hypothesis that photoinduction acts by changing the ability of the plant to transport hormones, rather than by changing the ability of organs to synthesize them, the transport of carboxy-labeled indole-3-acetic acid was measured in the short day plant Xanthium pensylvanicum. Plants grown under noninductive conditions were matched for… (More)
