Abstract
This study aimed to evaluation the effects of 5aminolevulinic acid which is the precursor of chlorophyll, in addition to glutamine, asparagine, arginine, proline, tyrosine and tryptophan on the date palm plantlets (Phoenix dactylifera L.) which produced by tissue culture in the green house after acclimatization to increasing the growth parameters of this plantlets. Complete randomized block design was used. to conduct the experiment at three treatments 100,200 and 300mg/l with three replicates and control treatment (without spraying), these treatments was subjected as weekly spraying one time/week, all plantlets received 3g/l NPK with irrigation water one time/week, vegetative growth parameters of plantlets were estimated (plant height cm, leaves number/plantlet, stem thickness cm and fresh and dry weight of leaves (g), also chemical leaves contents as, Indoles, chlorophyll a and b, total amino acids and total sugars. Results showed the response of growth parameters increased with foliar application of all amino acids treatment, lowest mean value was found with tyrosine application, maximum response for growth parameters was observed at the level of 300 mg/l of all treatments of amino acids as compared to (control treatment) non-sprayed plants. Leaves contents of indoles mg/g f.w., chlorophyll a and b Conference Proceeding Full Paper Rasmia et al.; IJPSS, Article no. IJPSS.2014.10.01
