| Abstract | ||
| An experiment was conducted in the lath house in the the Department of Horticulture . College of Agriculture,University of Baghdad. seedlings of Aloe vera plant were planted in plastic pots 28 cm in dimeter filled with sandyloam soil. The research contained two separate experiment. In the first experiment, nitrogen fertilizer was used as urea CO(NH2)2 46% applied to the soil at a rate of:0,0.5,1.0,1.5 g/ plant or as afoliar spray at a rate of :0,1,2,3 g / L.In the second experiment, cycocel was sprayed at the following concentration :0,500,1000,1500 mg/L .The experimental results showed that nitrogen at the rate of 1.5 g / plant significantly increased aloin and barbolin , Alotic acid and antracon up to 174.13 , 1321.75 , 501.14 and 187.50 micrograms / g .respectively as compared with the control treatment which produced 56.95 , 59.31 , 36.24 and 36.82 micrograms / g. The foliar spray with nitrogen at the rate of 2 g / L significantly increased aloin , Aloe-emodin , antracon and cinnamic acid to185.44, 709.07 and 396.74 micrograms/g. compared with 96.44 ,36.24 and 147.06 micrograms/ g in the control treatment.Foliar spray with cycocel at the rate of 1500 mg/L spryed twice significantly increased cinnamic acid, aloin , barbolin and aloe- emodin to 453.49 , 233.47 , 563.57 and 198.66 micrograms/g in the control treatment respectively 78.08 , 36.59 , 48.99 and 30.50 micrograms/g. Cycocel at 500 mg/L sprayed four times significantly increased barbolin and aloe-emodin to 662.44 and 437.49 micrograms/g, respectively as compared with 48 .99 and 30.50 micrograms/g in the control treatment . | ||
