Influence of Growth Regulators on Callogenesis and Somatic Embryo Development in Date Palm (Phoenix dactylifera L.) Sahelian Cultivars

Table 1

Influence of BAP on the biomass changes in suspension cultures and somatic embryos development after 5 weeks on PGR-free medium.

BA (mg/L)	Suspension culture; Fresh weight (g)	Embryo number per Petri dish	Vitreous embryo number per Petri dish
0	1.37^c	21^b	1^e
0.5	1.50^b	29^a	1.5^d
1	1.63^ab	18^c	3^c
1.5	1.66^ab	14^d	4.7^b
2	1.77^ab	11^e	5.1^a

Average values were calculated from 5 repetitions per condition of medium; letters indicate significative differences according to Newman and Keuls test at the level of 5%.
