AbstractThis experiment was conducted to study possibility of enhancing rooting of small attached Date Palm offshoots. This study includes two experiments:
stage No. 1: root formation, each treatment was replicated 5 times and each replicate was a small nursing offshoots .A small nursing offshoots connected to their mother plant (8-10cm diameter) of two varieties ( Braim and Khastawi) were subjected to the following treatments for enhancing root formation :control, Seradix powder contain 8000 mg/l IBA , Seradix powder Contain 16000 mg/l IBA , Seradix powder contain 32000 mg/l IBA, injection 5 ml from ( NAA+IBA) 1000 mg/l.
The results showed that injection treatment was superior in number, length and diameter of roots and newly formed leaves compared to control treatment but there is no significant difference between seradix powder 32000 mg/l IBA and injection treatment in dry weight percentage for root system. A clear varieted effect was found, where CV. Braim was superior in number, length, dry weight percentage for root system and newly formed leaves compared to CV. Khastawi.
stage No. 2: the surviving percentage, after 12 month the offshoots were separated from their mother plants and treated with fungicide(Ridomel)12 months from planting the ability of offshoots were tested for surviving : the surviving ( persisting )percentage was high with all treatments compared to control . Treatment (Seradix powder contain 16000 mg/l and injection treatment) gave 100% survival compared to control.
