THE EFFECT OF THE SPRAY WITH IRON, ZINC AND AUXIN IN THE GROWTH AND YIELD VOLATILE OIL THE ACTIVE INGREDIENT OF THE PLANT FOENICULUM VULGARE MILL IN SOIL GYPSUM

Abstract

Plant Foeniculum vulgare mill was one of the important aromatic medicinal plants containing volatile oils used in food and food industries. Field experiment carried out during The years (2013) in the College of Agriculture / University of Tikrit Research Station in the soil of gypsum to study the four concentrations of the effect of iron and zinc (0,2,4,6 g. Liter -1) of H2O. ZnSO4 g. L -1 (Zn% 35) and iron are FeSo4. 7H2O g. L -1 (Fe% 20) four concentrations of auxin (IAA) (0, 25, 50 and 75) M.L-1 these treatments arranged in a factorial experiment by randomized complete bloke design in three replicates. The results indicated that spraying to outweigh the transaction (Fe3 + Zn3) Iron moral weight in the qualities of the growth and respectively, where gave the highest value for recipes (Plant cm height and number of branches .plant -1 dry weight of the plant (g) and the number of inflorescences .plant- 1 and number of fruits and fruit weight of 1000 (g) and yields the fruits .H kg -1) was (145.27 cm), (10.22 B.plant -1), (148.54 g), (59.48 Nora .plant -1), (239.47 fruit .nor -1), (10.94 g), (2115.95 kg.H -1), respectively, compared to the treatment comparison that gave the lowest value of the recipes mentioned in the above. With respect to the concentrations of auxin shows the results to the superiority of treatment (A3) moral qualities in growth traits and yield, where he gave the highest value of the recipes (plant height 138.11 cm and the number of branches .plant -1 dry weight of the plant (g) and the number of inflorescences nor . plant -1 number of fruits and fruit weight of 1000 (g) and yield the fruits kg.H -1) was (138.11 cm), (9.91 B. plant -1), (170.47 g), (55.28 Nora . plant -1) (265.22 fruit .nor -1), (11.36 g), 2344.78 kg.H -1), respectively, compared to the treatment comparison that gave the lowest value of the qualities listed above . which gave the third highest value of the treatments recipes volatile oil qualitative and weight ratio the refractive index was (1.73% and 0.939 and 1.451), respectively, compared to the treatment comparison that gave the lowest value of the recipes above, either in terms of proportions of nutrients (nitrogen, phosphorus, potassium, zinc, iron) in the plant has outperformed the fourth treatment where gave values of (1.19) and (0.31) and (2.50) and (36.17) and (53.58) and, respectively, compared to the treatment comparison that gave the lowest value of those proportions. as with respect to the concentrations of auxin results reveal the existence of significant differences between the concentrations in their influence in oil content and proportion of nutrients in the plant, where he gave a fourth treatment highest value for the ratio of volatile oil quality, weight and refractive index and percentage of nutrients (nitrogen, phosphorus, potassium, zinc, iron) was (1.85%) and (0.947) and (1.46) and (1.33 ) and (0.37) and (2.56) and (36.58) and (55.87) and, respectively, compared to the treatment comparison that gave the lowest value for the recipes the above . that effective compounds that analyzed the device (the HPLC) where he gave a fourth treatment of interaction between the iron and zinc and auxin (Fe3 + Zn3 and A3) a higher concentration of the active ingredient (α-pinene, Methyl chavicol, Anethol, Fenchone, Limonene) was (4.40) and (4.15) and (13.98) and (15.88) and (12.08), respectively, compared to the treatment comparison
