Abstract
On applying IAA-GB and IAA-NAA mixtures to the hypocotyls of Helianthus annuus, the plants showed an increase and a decrease, respectively, in their phototropic response compared with the control treated with IAA-H2O only. In the in vitro experiments it was observed that the illumination (with 1,500 lux light, lasting for 24 hr) caused photoinactivation of IAA in the mixtures of IAA-H2O, IAA-GB and IAA-NAA by 50%, 24% and 0%, respectively. In the presence of 0.01% riboflavin as a photosensitizer in the same mixtures, the degree of photodestruction of IAA caused by the same illumination was 92%, 97% and 86%, respectively. The stronger positive phototropism in the IAA-GB treated hypocotyl was accounted for by the situation that on the illuminated side the photo-inactivation of IAA was accelerated by GB, while on the shaded side IAA and GB acted synergistically. On the other hand, the weaker phototropism in the IAA-NAA treated hypocotyl was explained as due to a partial inhibition of photoinactivation of IAA by NAA.
