KH2PO4 AND SUCROSE AFFECTED in vitro AND ex vitro DATE PALM PLANTLETS CV SAKOTY

Abstract: The acclimatization stage of date palm plantlets is crucial for increasing numbers of plants to culture in the open
field so to increasing the survival percentage of this stage in the greenhouse this study was done to improving
plantlets in the rooting stage in vitro by using different concentrations of KH2PO4 as full (170 mg L-1), full (170
mg L-1) + ¼ and full (170 mg L-1) + ½ and sucrose 30 as control treatment, 45 and 60 g L-1. The found results
exhibited the treatment KH2PO4 at full with 45 g L-1 sucrose proved to be the great treatment for increasing in
vitro height plants, while the root length and numbers and stem thickness were highly increasing under KH2PO4
full + ½ with 60 g L-1 sucrose, maximum hairy roots produced by full KH2PO4 +30 g L-1 sucrose, highest
numbers of leaves obtained on the medium supplemented by full KH2PO4 + ¼ with 45 g L-1 sucrose, the greatest
percentage of plantlets acclimatization under full + ¼ KH2PO4 with 30 and 45 g L-1 sucrose. More contents of
total indoles, chlorophyll a and b were present under full +1/4 and full + ½ KH2PO4 with 45 g L-1 sucrose. Up
on the previous results the treatment of full + ¼ or full + ½ KH2PO4 with 45 g L-1 sucrose is the preferable for
successful in vitro and ex vitro stages.
