| Abstract | ||
| This study was conducted at the nursery of certified citrus seedlings production which belongs to the Ministry of Agriculture/ Directorate of Horticulture and Forestry/ Kerbala Province (Hindyia District ) on six months -old lemon ( Citrus limon[ L.] Burm ) transplants grafted on three citrus rootstocks { sour orange ( Citrus aurantiumL. (,Volkamer lemon( C. volkamerianaTen and pas.)and SwingleCitrumelo ( C. paradise X P. trifoliata) to study the impact of citrus rootstocks and foliar application of NPK –TE andG-GANA and their interactions on some vegetative traits and the nutrients status. Randomized Complete Block Design was used with three replicates and test LSD used in order to Compare between means at 0.05 probability.Thetransplantswere sprayed four times ( in 15/4, 15/5, 15/8 and 15/9/2015). Types of rootstock have significant effects on all vegetative traits and nutrients concentration in leaves except diameter stock stem and total leaf area . Volkamer lemongave significant increase in number of branches, and carbohydrates in leaves, fresh and dry weight of shoot and root and leaves number Whereas SwingleCitrumelo had superiority in the traits of plant and length .Foliar application of growth stimulatorsG-GANA andNPK –TElead to significantl increase in vegetative and root characteristics and nutrient status compared with control except Mg in leaves. Spraying with 50 mg/l NPK –TEhad superiority treatmantSpraying with 100 mg/l NPK –TE gave asignificantlincreasing in leaf area.Whereas, Spraying with 100 mg/l G-GANAhad superiority in the traits of rootstock and scion stem diameter, number of branches and leaves number ,The interaction among rootstocks and growth stimulators G-GANA and NPK –TEhave significantly influenced vegetative and root growth. Lemon grafted on Volkamer lemon root stocks sprayed with 50 mg/l NPK –TE gave the highest values in plant height. Whereas , Lemon grafted on Volkamer lemon root stocks sprayed with50 mg/l G-GANA + 100 mg/l NPK –TE –gave the highest values in number of leaves. | ||
