Popis:	INCREASING concentration of heteroauxin in lanolin – water paste causes progressive inhibition of the growth of hypoeotyls of dark-grown Helianthus seedlings. At moderate concentrations definite swellings are produced. These effects can be considered as being the result of a progressive disorientation of the cytoskeleton with corresponding loss of cell polarity. A higher degree of disorganization would naturally lead to autolysis. In the presence of the sodium salts of alizarin and quinizarin sulphonic acids, the above effects can be so modified that it requires a higher concentration of heteroauxin to produce an effect similar to that produced with lower concentrations of heteroauxin alone. Tests with the alizarin sulphonate indicate that in aqueous solution it does not destroy heteroauxin to any great extent when this is estimated colorimetrically.
