Abstract
IN a recent communication, Curry and Gruen1 reported that sporangiophores of Phycomyces blakesleeanus showed strong negative phototropism when exposed to wave-lengths shorter than 300 mµ in addition to the positive phototropism in visible light known to earlier workers. They also showed that this negative response was due to a temporary increase in growth-rate on the side of the sporangiophore nearest the source of light, as they were able to demonstrate a ‘light-growth reaction’.
