ABSTRACT
The study was conducted during 2018 season, where acid lime rootstock seeds were soaked for 24 h in each of GA3 or ZnSO4 solutions at 750, 1500 and 3000 mg/l, separately along with distilled water as control, to evaluate their effects on the seed germination and some vegetative growth parameters. Results indicated that germination percentage was gradually reduced with increase in concentrations, while other vegetative parameters (plant height, stem diameter, leaf number, leaf area, plant fresh and dry weight) were progressively elevated with increasing of GA3 concentration or with reducing of ZnSO4 concentration.
Key words : Citrus, acid lime, GA3, seed germination, polyembryony, ZnSO4
