Effect of IBA, C1-sm, and the combination of both on pear root production and ex vitro survival.

Treatment	Emergence time (days)		Rooted explants (%)	Roots per explant (n)	Main root length (mm)	Ex vitro survival (%)
	First root	Last root
Control	-	-	0e	0e	-	0d
IBA (1 μM)	20 ± 4a	35 ± 1a	8d	1.0d*	7.9 ± 4.0b	83.4b
C1-sm (1 μM IAAequ)	7 ± 1c	14 ± 3c	58b	2.3 ± 0.3c	23.0 ± 2.7a	100a
2× C1-sm (2 μM IAAequ)	9 ± 2bc	ND	33c	2.8 ± 0.9b	9.1 ± 2.4b	ND
C1-sm + IBA	12 ± 1b	21 ± 5b	71a	4.0 ± 0.3a	10.2 ± 1.9b	66.6c

ND = not determined. Days until the first emergence of adventitious roots from the stem tissues; days occurred for the last adventitious root emergence from the stem tissues; the percentage of rooted explants; the number of roots per explant; the average of the longest root observed in each rooted explant; the percentage of ex vitro survival. Values represent the average ± se. Different letters indicate statistically significant differences between groups.

^*Only one explant rooted for each repeated trial.
