Effect of KAR1 treatment on the root development of Gala apple tissue culture-generated plants. In the treatment of different concentrations of KAR1 (0, 1 nM, 5 nM, 50 nM and 500 nM), IAA−induced rooting of Gala apple tissue culture−generated plants were conducted (A). The concentration of IAA was 0.1 mg·L-1. Photographs were taken after photoperiod culture for 58 d (25°C, 16 h light and 8 h dark). The total root length (B) and root projection area were calculated (C). The contents of the root hormones ABA (D), GA3 (E), and TZR (F) in apple seedlings subcultured with KAR1 for 4 days at concentrations of 0, 1 nM, 5 nM, 50 nM, and 500 nM were determined. Three independent experiments were conducted. One−way ANOVA and multiple comparisons via Fisher’s LSD test were performed, and different characters at the top of the columns indicate significant differences (p<0.05). The homoscedasticity and normal distribution of the data were confirmed by Levene’s test and the Shapiro−Wilk test, respectively. Scale bar = 2 cm.
