Rooting response of in vitro generated N. amplexicaulis shoots cultured on full strength MS supplemented with varying concentrations of NAA
| NAA (mg/L) | Percent of shoots with roots | No. roots per shoot | Root length (mm) |
|---|---|---|---|
| 0 | 14.29 ± 6.6a | 2 ± 0.41a | 40.25 ± 5.27a |
| 0.2 | 30.78 ± 7.4a | 2.75 ± 0.33a | 21.45 ± 4.88b |
| 0.6 | 23.5 ± 7.2a | 2.16 ± 0.52a | 12.5 ± 1.6b |
| 1.0 | 14.7 ± 6.1a | 2.17 ± 0.48a | 14.62 ± 2.46b |
| n ≤ 39 | n ≤ 12 | n ≤ 33 |
Values are means ± SE after 4 weeks on media. Means followed by the same letter in a column indicate no significant difference by Tukey’s multiple comparison test or pairwise Fisher's exact test (P < 0.05)
