| Abstract | ||
| Lath house trial was conducted out at Horticulture and Landscape Design Department, College of Agriculture, University of Baghdad ( Abu-Ghraib ), the alternative porition of University of Anbar, for the period from April 2017 to January 2018 to study the effect of foliar spraying with growth regulator ( Thidiazuron ) ( TDZ ) and nutrient solution ( Folizyme-GA ) in some growth and minerals traits of Marumi Kumquat saplings, 108 uniform saplings were selected in their growth as much as possible at the age of three years, a factorial experiment was conducted according to the Randomized Complete Block Design ( RCBD ), with three replicates for each treatment, the experiment included spraying with four concentrations of growth regulator ( 0 , 10 , 20 and 30 mg l-1 ), and three levels of spraying with nutrient solution ( 0 , 1 and 2 ml l-1 ) . The results showed that the two factors of the study had a significant effect in all studied traits, especially the foliar application treatment of ( TDZ ) at 20 mg l-1 and spraying with nutrient solution of Folizyme-GA at a concentration of 2 ml L-1, where achieved a significant superiority in the average increase in number and length of main shoots, number of leaves, leaves area, dry weight of vegetative parts, percentage of carbohydrates in shoots, leaves content of nitrogen, phosphorus, Potassium and chlorophyll, which recorded 9.50 shoot . sapling -1, 8.58 shoot . sapling -1, 32.86 cm, 32.64 cm, 417.8 leaf . sapling -1, 394.1 leaf . sapling -1, 84.99 dm2, 78.96 dm2, 124.30 gm, 112.98 gm, 9.40, 9.19, 2.52, 2.47, 0.30, 0.31, 1.69, 1.72%, 10.98 mg gm-1 fresh weight and 10.80 mg gm-1 fresh weight respectively for both factors of the study, while the control treatment gave the lowest values for all above traits . | ||
