| Abstract | ||||
| A greenhouse expermint was carried out to study the effect of soaking date palm plantlets cv. Bertmoda in different fresh cyanobacterial cultures including, Spirulina platensis, Nostoc muscorum, Anabaena oryzae, Azolla pinnate either individually or a (mixture of all ) and humic acid on adventitious roots per plantlet (pre treatment) before planting in soil and subsequent survival percntage in acclimatization stage. The number and length of adventitious roots formed on the basic root of plantlets significantly increased when plantlets were soaked in all inocula and humic acid respectively with the superiority of Spirulina Platensis. Also numbers of leaves, leaf length, leaf width, number of main roots, length of main root, length of adventitious roots after 6 months of adaptation significantly increases, the highest increases were observed when plantlets were treated by Spirulina platensis. Besides survival percentage of plantlets and formed indol, chlorophyll a, b and carotenoids contents, in plantlet leaves after 6 months of adaptation significantly increased in response to the various treatments used with the superiority of Spirulina platensis. It is recommended to soak plantlets (pre treatment) received from tissue culture micropropagation technique of date palm in 20cm Spirulina platensis for 3-4 days before planting in soil and drench soil with Spirulina platensis after planting to obtain the best adventitious root and high survival percntage of plantlets at acclimatization stage. | ||||
