| Abstract:
Two hundred eighty one plantlets representing 18 cultivars produced through tissue culture and obtained from different laboratories around the world were transplanted in the date palm germplasm bank in King Faisal University, Saudi Arabia in 1986-1989.The evaluation was conducted until 1999. Annual survival rate for each cultivar was determined. Genotypic differences and environmental factors such as maximum and minimum air temperature, pan-evaporation, and water table level were considered for evaluation to determine their effects on survival and adaptability of newly planted date palm plantlets. The results revealed high survival rate and no significant difference were detected between cultivars, sources of plantlets, and seasons of transplanting. The high survival rate was due to the good root system that developed before transferring plants to the field, and their gradual adaptation to the area. | |
