Comparison of Rooting Situations for Salakhani and Zivzik Pomegranates Under Different Iba Doses
(Aloki Applied Ecological Research and Forensic inst Ltd, 2020) Al-Jabbari, K. H.; Pakyurek, M.; Yavic, A.
Rooting performance of Salakhani, a local variety of Iraq and Zivzik (Punica granatum L.), a local pomegranate of Siirt, were compared in our study. For this purpose, the effect of different doses of indole butyric acid (IBA) (0.00, 1000, 2000, 4000, 6000 mg / L) on rooting was examined. Cuttings were kept in the rooting environment for five months and rooting rates, root number, root lengths, survival rates, shoot lengths, shoot and leaf number were determined Salakhani were found to be the best cultivar only in terms of the root length, sprout length, shoot number and leaf number. Zivzik were found to be the best variety with regard to the other properties. IBA application of 4000 ppm was found to be the best all the shoot number, leaf number and root length. The hormone dose of 6000 ppm was found to be the most beneficial for survival and rooting rates. Application of 1000 ppm was found to be the best dose among the doses of hormone only on account of root number.
Effect of Seaweed Application on Nutrient Uptake of Strawberry Cv. Albion Grown Under the Environmental Conditions of Northern Iraq
(Aloki Applied Ecological Research and Forensic inst Ltd, 2020) Al-Shatri, A. H. N.; Pakyurek, M.; Yavic, A.
This pot experiment was carried out to investigate the effects of four doses (0, 2, 4 and 8 g.L-1) of seaweed extract (Alga 600) application with fertigation on nutrient uptake of strawberry cv. Albion during the 2016-2017 vegetation period in Kalar city located in Northern Iraq. The results of leaf analysis indicated significant (p<0.01) differences at the nitrogen (N), phosphorus (P), potassium (K), magnesium (Mg), calcium (Ca), manganese (Mn) and iron (Fe) concentrations between two sampling periods. In contrast, copper (Cu) and zinc (Zn) concentrations of plants leaves did not significantly differed between the sampling periods. According to the statistical analysis, the effect of seaweed doses on nutrients were statistically insignificant for all nutrients except Mn (p>0.05). While for the Mn element, the highest value (223.70 +/- 11.59 mg kg(-1)) obtained from T4 (8 g.L-1) seaweed dose; the lowest one (164.91 +/- 11.59 mg kg(-1)) obtained from control dose. The effect of interaction between seaweed doses and periods on nutrients was also not found statistically significant (p>0.05). In general, seaweed extract of 8 g.L-1 was more effective on macro and micro nutrient contents of strawberry leaves.
Effect of Seaweed Application on the Vegetative Growth of Strawberry Cv. Albion Grown Under Iraq Ecological Conditions
(Aloki Applied Ecological Research and Forensic inst Ltd, 2020) Al-Shatri, A. H. N.; Pakyurek, M.; Yavic, A.
This experiment was established in pots during the vegetative period of 2017, in Kalar Sulaymaniyah, Northern Iraq, to investigate the effect of seaweed extracts (Alga 600) of four concentrations (0, 2, 4, 8 g.L-1) applied with fertigation system on growth, flowering, yield and quality properties of strawberry cv. Albion. Drip irrigation system was used in this experiment. According to the results in terms of the vegetative growth characteristics, increasing seaweed extract (Alga 600) amounts had significantly different effects on plants with a different number of crowns. The results concerning flower properties show that increasing seaweed extract applications had significant effects on the number of flowers per plant, yielding 16.55-21.77 units/plant. The results in point of fruit properties show that increasing Alga 600 amounts caused a significant increase of 11.81-17.7 units/plant in terms of fruit number, 211.74-329.37 ml in terms of fruit volume, and an increase of 191.7-295.03 g in terms of yield, compared to the control treatment. The results show that increasing seaweed extract caused a significant increase in fruit quality (TSS/TA ratio from 8.29 to 13.35) compared to the control treatment and increasing seaweed application caused a significant decrease in the TA of the fruit.
Fatty Acid, Mineral and Proximate Compositions of Various Genotypes and Commercial Cultivars of Sweet Almond From the Same Ecological Conditions
(Corvinus Univ Budapest, 2018) Simsek, M.; Gulsoy, E.; Yavic, A.; Arikan, B.; Yildirim, Y.; Olmez, N.; Boguc, F.
This study was carried out on the fatty acid, mineral and proximate compositions of ten sweet almond genotypes and two commercial varieties named as Ferragnes and Ferraduel grown in the same ecological conditions known as the Firat riverside region during two consecutive years. In this context, the crude oil (Co), crude protein (Cp), total sugar (Ts), total ash (Ta) and moisture (Mo) contents from the almond genotypes and cultivars ranged from 48.69 to 55.8%, 20.41 to 25.82%, 2.92 to 5.27%, 3.29 to 4.66% and 2.52 to 3.75%, respectively. The genotypes and cultivars showed a varied mineral content as well. Potassium (K) was the main mineral in all genotypes and cultivars, ranging from 679.53 to 986.63 mg100 g(-1) ; phosphorus (P) was the second most abundant mineral, ranging from 584.57 to 697.31 mg100 g(-1) ; followed by magnesium (Mg) and calcium (Ca), ranging from 325.27 to 381.93 mg100 g(-1) , 250.15 to 332.19 mg100 g(-1) , respectively. Of the identified fatty acids, oleic acid (Oa) (69.76-72.02%) was the predominant fatty acid, followed by linoleic acid (La) (18.82-21.62%), palmitic acid (Pa) (5.627.76%), and stearic acid (Sa) (1.20-1.69%). Other fatty acids were present at trace amounts. The unsaturated (Ufa)/saturated fatty acid (Sfa) ratios ranged from 9.29 to 12.12. From the results of the present study, we can conclude that the kernels of almond genotypes and cultivars are being potential sources of valuable oil which might be used for edible and other industrial purposes.
