The Effects of IBA, IAA, and NAA as Growth Regulators for Nepenthes Truncata

---

Nepenthes truncata is an endangered ornamental plant that has increasing demands due to
its exotic look, commercial value and various medicinal properties. Previously, INAGRO has
attempted to subculture and preserve the N. truncata but did little to no avail, although other
nepenthes available in the institution were able to grow well in the same media. Some N. truncata
explants even had no roots and a tiny amount of leaves. Therefore, an attempt to increase the
growth of N. truncata, mainly on its roots and leaf initiation was assessed in this study by utilizing
different auxin plant growth regulators (PGRs), namely Indole-3-butyric acid (IBA), Indole-3-acetic
acid (IAA) and 1-Naphthaleneacetic acid (NAA) at different concentration ranging from 0.5 - 3 mg/L.
This project aimed to determine the most suitable auxin PGR (IBA, IAA and NAA) to support the best
growth and development root and leaves of N. truncata. The observed parameters were time of
adventitious root emergence, number of adventitious roots, adventitious root length and number of
leaves. These parameters were assessed individually by one way parametric ANOVA-F, one way
ANOVA-Welch for non homogenous samples, and nonparametric Kruskal-Wallis ANOVA with SPSS
IBM26. The results showed higher means and significance from the IBA group, mainly IBA 3 mg/L for
all parameters and followed by IBA 1 mg/L.
