In vitro germination and growth of Argania spinosa of Beni Snassen (Eastern Morocco) at various concentrations of NaCl

The present work intends to study, salt effect (sodium chloride) on in vitro germination and growth of Argania spinosa. The test was conducted in a grouth chamber where temperature and photoperiod were controlled. Seeds were put to germinate in tubes test with a gelose middle (Agar + water). Six concentrations of NaCl were tested. Results showed that there is not significant difference of germination between the witness and NaCl concentrations of 1 g/l, 3 g/l and 5 g/l. A significant difference has been found between the witness and the germination of almonds to concentrations of NaCl to 7 g/l and 9 g/l. The emergence of the stem axis follows the same evolution. With regard to the growth, measures of lengths of the main root and the stem axis showed a significant difference for the all concentrations tested. The statistical analysis to 5% showed that there is a significant effect of salt on the production of the aerial and root biomass.
