Effects of naphtalenacetic acid on potato meristem tip development

Short Communication


0.4 μmol/l naphtalenacetic acid (NAA) stimulated early root formation and caused highly significant increases in numbers of rooted plantlets (from 55 to 74%) when potato meristem tips were cultured in a medium supplemented with gibberellic acid (GA). When the medium lacked GA, 0.1 μmol/l NAA induced complete development in about 30% of the explants. Higher concentrations inhibited root and shoot growth and induced conspicuous callus formation, both in the presence and absence of GA.

Low NAA concentrations were thus useful in obtaining accelerated and more uniform development in the potato meristem tip population.
