A novel visual marker to distinguish haploids from doubled haploids in rice (Oryza sativa, L) at early growth stages

Table 2 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 ± 0.47^b	12.21 ± 1.66^a	0.34 ± 0.03^b	38.8 ± 2.51^a	0.380 ± 0.01^b
Acute leaf apex	4.43 ± 0.35^a	11.94 ± 1.36^a	0.46 ± 0.04^a	26.77 ± 0.84^b	0.55 ± 0.02^a
Maturity stage
Attenuate leaf apex	37.22 ± 3.92^a	32.55 ± 2.31^a	1.50 ± 0.07^a	21.85 ± 1.45^a	0.324 ± 0.01^b
Acute leaf apex	15.74 ± 2.18^b	21.06 ± 1.64^b	0.96 ± 0.07^b	22.33 ± 1.26^a	0.620 ± 0.04^a

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
