Leaf morphology parameters of androgenic plants differing in the leaf apex

Androgenic plants	Leaf area (cm2)	Leaf length (cm)	Leaf width (cm)	Leaf index	Leaf apex area (cm2)
Post-hardening stage
Attenuate leaf apex	3.10 ± 0.47b	12.21 ± 1.66a	0.34 ± 0.03b	38.8 ± 2.51a	0.380 ± 0.01b
Acute leaf apex	4.43 ± 0.35a	11.94 ± 1.36a	0.46 ± 0.04a	26.77 ± 0.84b	0.55 ± 0.02a
Maturity stage
Attenuate leaf apex	37.22 ± 3.92a	32.55 ± 2.31a	1.50 ± 0.07a	21.85 ± 1.45a	0.324 ± 0.01b
Acute leaf apex	15.74 ± 2.18b	21.06 ± 1.64b	0.96 ± 0.07b	22.33 ± 1.26a	0.620 ± 0.04a

Student t-test was used to compare the means of two groups of plants (attenuated and acute leaf apex)

Mean ± standard error; a and b letters indicate a significant difference in Duncan’s multiple range test at p < 0.05

Means are averages of 10 replicates of androgenic regenerant lines

Leaf apex area refers to the area of the leaf measured in the region 1 cm from the tip
