In vitro rooting of P. strobus. a Root formation from elongated adventitious shoots at different time points of culture on media with 0.01 μM IAA. Roots formed from elongated adventitious shoots were shown at 7, 21, 35, and 49 days of culture. b Rooting rate of shoots derived from genotypes 1-721, 2-007, 3-011, and 3-101 on medium containing 0.01 μM IAA. Each treatment was replicated five times, and each replicate consisted of 30–50 shoots. Values represent the mean ± SD. Values followed by one asterisk are significantly different from the corresponding control value (P < 0.05; n = 5) by ANOVA
