Résumé partiel
This study was executed during the period from 2014 to 2015 at the tissue culture laboratory of Horticulture Dept., Faculty of Agriculture, AssiutUniversity.Two (Musa spp.) banana cultivars namely Grand Nain (G) and Zeev (Z) grown in vitro were used in this study as explants. The propagated plants were subcultured every 6 weeks for multiplication in 500 ml culture jars contained MS medium (Murashigae and Skoog, 1962). Tolerance experiment : In this experiment, each of the two above mentioned cultivars were subcultured on Two media each contained one of the two osmotic agents : 1-Sodium chloride (NaCl) at 0, 30, 60 , 120 and 200 mM/L . 2- Polyethylene glycol (PEG 600) at 0,10,20,30 and 40 g/L . Measurements : Data samples were collected after 6 weeks for each experiment, plantlets were washed up from the agar or media residues with sterilized water and the following traits were measured for each experiment : A)Vegetative Parameters : The vegetative parameters were ; plantlet height (cm), average number of leaves/explant and plantlets fresh and dry weight (g). B)Physiological Parameters :
