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.
