Alteration in seedling geotropic response with indolyl-3-acetic acid and morphactin



Alteration in seedling geotropic response with indolyl-3-acetic acid and morphactin



Zeitschrift fur Pflanzenphysiologie 90(4): 309-318



Increase in IAA conc. from 10-8 to 10-4M disturbed but did not abolish the geotropic response of hypocotyl and root in Sinapis alba and lettuce seedlings. Some inversion of seedlings occurred between 10-6 and 10-4M IAA, but <5% of the total seedlings were affected. The methyl ester of morphactin (CFMe) also disturbed the geotropic response of hypocotyl and root, but increasing CFMe resulted in random orientation of hypocotyl and root.
