Effect of thidiazuron on morphological and flowering characteristics of Dendrobium ‘Sunya Sunshine’ potted plants

Table 1, p. 173.

Table 1. Effect of TDZ concentrations on the vegetative growth parameters of Dendrobium ‘Sunya Sunshine’ potted plants.

Treatment	Stem height (cm)	Stem diameter (mm)	Leaf length (cm)	Leaf width (cm)	Number of new shoot
TDZ0	17.63±1.74 a^a	14.38±0.67 b	10.62±0.59 ab	3.52±0.08 a	0.33±0.21 c
TDZ30	16.88±0.78 a	16.42±0.27 a	10.02±0.32 b	3.56±0.15 a	1.83±0.17 a

TDZ90	17.83±1.05 a	13.88±0.54 b	11.64±0.27 a	3.05±0.09 b	0.50±0.22 c
TDZ120	17.04±0.65 a	14.34±0.73 b	11.09±0.26 ab	3.28±0.16 ab	0.33±0.21 c

Notes: TDZ_{0, 30, 60, 90, 120} represented the TDZ concentration of 0, 30, 60, 90 and 120 mg·L⁻¹, respectively.

^aThe data were measured at the 60th days after first treatment and represent means of 30 plants per treatment ± standard error. Different letters indicated significant differences at P≤5%.

Stem diameter was measured at the thickest point, typically 3.0–4.0 cm above the bottom of the new stem. The unit of the stem diameter in Table 1 was incorrect – it should be ‘mm’ rather than ‘cm’. As a result, the revised Table 1 has been re-supplied by the author and should replace the existing Table 1 on page 173.

Table 2, p. 175.

First flower duration is the number of days counted from the bloom to the wilt of the first flower. Flower duration is the number of days counted from the bloom of the first flower to the wilt of the last flower of the plant.

Table 2. Effect of TDZ concentrations on the flowering timing and duration of Dendrobium ‘Sunya Sunshine’ potted plants^a.

Treatment	First inflorescence emergence time (days)	First flower bloom time (days)	First flower duration (days)^b	Flower duration (days)^c
TDZ0	28.0 ± 0.7 a	65.2 ± 1.0 b	54.2 ± 1.9 a	75.0 ± 2.4 a
TDZ30	22.0 ± 1.4 b	63.3 ± 1.5 b	55.8 ± 2.2 a	69.2 ± 4.4 a
TDZ60	22.2 ± 1.2 b	67.8 ± 1.1 ab	51.5 ± 1.7 a	67.0 ± 4.3 a
TDZ90	23.0 ± 1.8 b	71.8 ± 1.9 a	34.7 ± 3.4 b	43.2 ± 6.2 b
TDZ120	24.8 ± 1.0 ab	70.8 ± 2.1 a	30.2 ± 2.1 b	49.7 ± 5.1 b

^aAll the statistical data were based on the number of floral bud formation and flowering plants. First inflorescence emergence time and first flower bloom time were calculated from the day of first treatment. The data represent means of 30 plants per treatment ± standard error. Different letters indicated significant differences at P ≤ 5%.

^bFirst Flower duration is the number of days counted from the bloom to the wilt of the first flower.

^cFlower duration is the number of days counted from the bloom of the first flower to the wilt of the last flower of the plant.

Page 171.

The last sentence on page 171 should read:

“Although TDZ use would cause morphological abnormalities, genetic evaluation of TDZ-induced explants using flow cytometry, inter-simple sequence repeat (ISSR), molecular markers, and directed amplification of minisatelliteregion DNA (DAMD) has shown uniformity and stability in genome size and consistent ploidy level (Faisal et al. 2014).”
