REGULATION OF AUXIN COMPOUND IN IN VITRO CULTURE OF GO POTATO SEEDS PRODUCTION

Abstract

Auxin has a role in the growth and development of plant roots. This research examined
the effect of IAA and NAA growth regulators in in vitro culture of potato. Employing group
randomized design, this research was conducted in "Plant improvement" in vitro laboratory
of FPP UMM. The results showed that the auxin compound which served as a growth
regulator substance had a significant effect on shoot and root induction of in vitro potato. IAA
compound was faster in inducing roots compared to NAA, but IAA could also reduce the
number of roots. IAA addition could strengthen the plant during acclimatization.
