Propagation of Epipremnum aureum stem cuttings under synthetic and alternative rooting hormones
Rooting hormones for plant propagation are commonly used, especially by those who have difficulty growing plants. Although different synthetic hormones are available and ready to use, they can be costly. This study compared three different naturally-derived alternative rooting hormones (Aloe vera gel, garlic, and turmeric extracts) to the commercially-available synthetic rooting hormone, called TakeRoot®, in propagating stem cuttings from Epipremnum aureum. The active ingredient in synthetic hormone was IBA (Indole Butyric Acid, 0.01%). The E. aureum stem cuttings were placed in hydroponic pots and observed for 30 days. Data from the five parameters: (1) number of roots per stem cutting, (2) number of rooted cuttings, (3) length of the longest and (4) shortest roots of the cuttings, and (5) mean rooting time, were collected as the basis for comparison. Image J software was utilized to measure the root length of the stem cuttings. The collected data were interpreted using Analysis of Variance for a factorial Complete Randomized Design, and a mean comparison was made using Duncan’s multiple range tests. Among the alternative rooting hormones, stem cuttings treated with garlic and turmeric extracts did not produce significant results. Stem cuttings treated with Aloe vera gel have produced the longest roots compared to the synthetic rooting hormone. At the same time, there is no significant difference (p<0.05) in the means of synthetic and alternative rooting hormones. This study provided scientific evidence on applying naturally-derived rooting hormone in the propagation of stem cuttings. Further, the Aloe vera gel, known for plant growth benefits, is the best choice for plant root propagation.
