Resumo
Plant tissue culture favors the growth of a new plant out of its natural environment.
This technique has been used for massive and fast plant multiplication. The aim of
this study was to compare the development of an orchid species under different
concentrations of auxins as growth regulators. The plant material consisted of Cyrtopodium saintlegerianum seedlings subjected to seven treatments of
naphthalene acetic acid (NAA) and indole butyric acid (IBA) at concentrations of 0,
1.0, 2.0, and 4.0 mg.L-1, respectively. After 60 days were evaluated the number of
leaves, roots and shoots; roots length and plant height. The results indicate that the
addition of plant growth regulators (auxins) to the culture medium had specific effect
on each variable collected by acting differentially on organogenesis. The best results
suggest that moderate auxin concentrations increase the number of roots and
shoots.
