Abstract
Shoot tips from two strawberry (Fragaria anariassa L.) cultivars, Gabi and Edpeeren were cultured on MS medium supplemented with 0, 0.5, 1.0, 1.5 or 2.0mg /1 of BA to study their effects on number, length, fresh weight and dry weight of shoots. The study also included measuring the effect of different concentrations of IBA (0 , 0.1 , 0.3 , 0.5 or 1.0) mg / l on rooting percentage, roots number and length. This study also included the acclimatization processes for plantlets in sand and a mixture of sand and peat moss media. Results indicated that addition of BA to the nutrient medium led to a significant increase in all investigated traits in comparison with the control with obvious superiority of 2 mg /l which reflected positively on the mean number of shoots (20.0) shoots / plant, the fresh and dry weight were 1237.73 and 136.4 mg respectively, especially with Gabi cultivar, the result showed that all the levels of IBA in the nutrient medium led to 100% rooting after 6 weeks of planting of both cultivars compared with 50% of in control. It was also noticed significant increases in the roots number and shoot lengths when IBA concentration was increased in the medium. The best growth for the rooted plantlets was found to be 1:1 sand: peat moss which showed survival percentages of 80 and 90% after 4weeks of planting Erdpeern and Gabi cultivars respectively.
