Development of pear shoots within 4 months after planting in a greenhouse at an air temperature of (35 ± 1) °C. The results of the root collar diameter (a,b) and the scion growth (c,d) measurements are presented for 7 experimental groups: control, direct treatment with various DBD CAP exposure durations (15 s, 30 s, and 45 s), and indirect treatment with PTS diluted in DW in three proportions (1:5, 1:10, and 1:20). Number of samples in each experimental group is presented in Table 1, and number of measurement repetitions was 5. * indicates a significant difference at 5% level in comparison with the control (p < 0.05, ANOVA). Data are presented as mean values and standard errors of the mean.
