Efficient Shoot Organogenesis Using Leaf Disc and Nodal Explants of Passion Fruit (Passiflora edulis Sims) and Genetic Fidelity Assessment Using Sequence-Related Amplified Polymorphism (SRAP) Markers

Table 3

Effect of putrescine on rooting of nodal explants of KPF 4 and purple passion fruit varieties.

Passion fruit variety	Conc. of putrescine (%)	Percentage rooting response (%)	Mean no. of roots	Mean root length	Mean no. of new leaves
Purple	0.0	66.7	3.33 ± 1.2	1.2 ± 0.6	0.0
	0.5	100	10.6 ± 1.0	5.8 ± 0.7	3.8 ± 0.3
	2.0	100	11.2 ± 0.8	5.5 ± 0.8	3.8 ± 0.3
KPF 4	0.0	0	0.0	0.0	0.0
	0.5	100	11.7 ± 2.2	5.5 ± 0.8	3.7 ± 0.4
	2.0	80	7.8 ± 3.6	3.4 ± 0.3	1.0 ± 0.7

Values represent mean ± standard error of 10 replicates per treatment in three repeated experiments. Means with the same letter within a column are not significantly different at according to Tukey’s Honest significant difference test.
