Table 1 Effect of MS, B5 and WPM on shoot initiation during the establishment stage of L. barbarum

Media type	% of growth initiation	Mean number of axillary shoots/explant	Mean length of axillary shoot (cm)	Mean leaf number/shoots
MS	91^a	2.2^a	2.50^c	5.1^a
B5	85^b	1.8^b	3.03^b	4.1^b
WPM	80^c	1.8^b	3.50^a	3.5^c

Means followed by the same letter are not significantly different according to Duncan’s multiple range test. The mean difference is significant at the 0.05 level. The presence of different letters in the same table indicates a high significance between the numbers. The higher significance between the results obtained, this leads to the numbers taking different letters
