In: Mansoura University Journal of Agricultural Sciences 2003.v.28(6)Summary: This study perfonned, at Central Laboratory for Research and Development of Date palm at Giza during the period from 2000-2002, to produce a new date palm plants instead of oldest, diseased, affected by red (Indian) palm weevil trees and protect an important semi-dry date paJmQJItivars from extinction, using tissue a.JIlure techniques. Rapid production with maintain the original off-shoots of some semi-dry date QJltivars (Army and Aglany) in Shar1da Governorate was the main target of this study. The results of this investigation the highest showed significant values of browning percentage observed in the leaf primordial explants of date palm Arnry 01. extended in the subsequent cultures for 32 weeks. caJlus formation was superior by using Amry 01., shoottip explants and QJlturing explants for 32 weeks. Embryogenic caUus formation significantly affected by using different growth regulators containing-media. MB medium produced the highest significant value of embryogenic callus formation and also Amry 01., a.JIlure period for 32 weeks were superior in this respect. Embryogenic callus ofAmry 01. PJ!duced the highest significant value of embryo formation after 12 weeks. M1, M3 and M7 were the most effective media to produce highest significant value of embryo formation.
