İbrahim Aydın | Betül Pak | Duygu Algan | Nuh Ocak
This study was carried out to investigate the floristic features (family, preference by grazers, growth form and response to grazing) and qualities of forage species collected from mountainous rangeland (Akdağ Mountain, Ladik) in the middle Black Sea region of Turkey. Forage samples were collected five times by 15-day intervals from the before-flowering stage to the after-flowering stage in 2015 and 2016. The total number of species was 105 species belonging to 73 genera and related to 26 families. Of the total species, 20 were from Poaceae (19.0%), 30 were from Poaceae (28.6%). Rests of the species belonged to other families (52.4%) dominated by families such as Asteraceae (13/55) and Lamiaceae (6/55), of which 26 species were weeds harmful to animals. While the percentages of decreaser, increaser and invader species were 16.2, 12.4 and 71.4, those of annual, biennial and perennial species were 31.9, 2.9 and 65.2, respectively. The number of species preferred by grazing was 74 (70.5%), while the number of non-preferable species was 31 (29.5%). The ME (MJ kg-1), RFQ and quality category of legumes, grass, and other botanical families were found as 8.88±0.07, 130.9±3.05 and very good, 8.00±0.07, 83.2±1.62 and good, and 8.98±0.07, 141.0±3.62 and premium, respectively. These results can be used as a management tool to improve rangeland quality and sustainability. The evidence from this study is that floristic pattern is not merely a result of invader forage species, but also might be a beneficial result that deserves further study for mountainous rangelands.

In agricultural production, one of the limiting factors on plant growth and yield is soil salinity. The plant growth regulators are of considerable importance in alleviating the negative effect of salt stress. The study was carried out to determine the effects of salicylic (SA) and gibberellic acid (GA3) on the growth and some physiological characters in canola (Brassica napus L.) under salinity conditions in greenhouse. For this purpose, a factorial experiment set up as completely randomized design was conducted with three levels of SA (0, 0.5 and 1 mM) and GA3 (0, 50 and 100 mg l-1) and four levels of NaCl (0, 50, 100 and 150 mM) with three replications. In the study, leaf area, plant height, electrolyte leakage, chlorophyll content and the loss of leaf turgor were investigated. Salt treatments reduced significantly all of the considered parameters, compared with the control. Salinity caused a significant reduction of 63 and 67%in plant height and leaf area, respectively, as compared to the control plants. On the contrary, electrolyte leakage was markedly increased (six-fold) with increasing NaCl levels. Gibberellic acid increased significantly plant height and reduced the loss of leaf turgor, without a significant improve in other parameters. The results indicated that application of SA and GA3 to salinity stressed plants did not significantly affect canola vegetative growth. However, GA3 caused a partial decrease in the adverse effect of salinity.

Oat breeding activities at the Transitional Zone Agricultural Research Institute (TZARI) have been continuing since 1929. Within the scope of this study, it is aimed to select those that are high in yield and quality from local oat lines that are compatible with regional conditions and to register them as new oat cultivars. Field trials were conducted in rainfed conditions in Eskişehir TZARI Central and Hamidiye Campuses in the 2017-2018 crop season. In the study, ninehteen local lines (Avena sativa L.) collected from different parts of the country and Checota, Kahraman, Kırklar, Yeniçeri and Sebat varieties as a standard were used. In this research, besides various agro-morphological traits such as grain yield (GY), thousand kernel weight (TKW), plant height (PH), lodging score (LS), heading days (HD), grain protein content (PC), beta-glucan (BG), acid detergent fiber (ADF) and neutral detergent fiber (NDF) values were examined. According to the results of this study, differences between genotypes in parameters other than ADF and NDF values were found statistically significant. The means of grain yield was 2,93 t ha-1, and the GY of genotypes was ranged from 2,31 to 3,58 t ha-1 in the trial. TKW was ranged from 25,5 to 37,1g; PH was 83,3 to 130,2 cm; HD was 126,0 to 141,0 days; BG was 3,29 to 5,16%; PC was 13,4 to 15,9%; ADF was 16,4 to 19,4%; NDF was 30,8- 38,8% in the genotypes. Accordingly, G13, G16, G19, G21,G22 and G23 local oat lines have been found to be promising in terms of targeted agro-morphological and quality characteristics and transferred to advanced level in the oat breeding program.

Muhammad Fakhar-e-Alam Kulyar | Zeeshan Ahmad Bhutta | Moazam Ali | Shah Nawaz | Muhammad Asif
Traditional medicine is still the only treatment in many rural areas especially the rural communities of east. Due to limited access to modern medicine, local people use medicinal plants to treat most diseases. Some herbs contain powerful contents and must be treated with the same precautionary care as in the case of drug, we do. In fact, a lot of drugs are basically based on artificial verities of natural composite in plants. For example, the heart drug Digitalis comes from a foxglove plant. Some drugs are single active substance derived from botanical sources. Herbalists believe that if the active ingredient is isolated from other parts of the plant, its action may be lost or its safety may be reduced. E.g, salicylic acid is present in a plant of meadowsweet which is used for aspirin production. Aspirin may cause bleeding in the gastric mucosa, but meadowsweet contains some other compounds naturally that interfere with the stimulation of salicylic acid. According to some practitioners, the effect of whole plant is greater than its parts individually. Critics believe that the nature of the herbs makes itself difficult to administer of such active ingredients. Herbs contain active ingredients, Mostly of them have unknown ingredients. As with other prescription drugs, herbs should always be prescribed by a qualified doctor.

Adem Yağcı | Seda Sucu | Namık Yıldız
The amount and area of the leaves should be at an optimum level in order to maintain the product quality and not to adversely affect the vine growth. Because carbohydrates, which are essential for omca and are mostly stored in fruit and wood, are formed by leaves after photosynthesis. Leaf area can be used in many areas. Among these, photosynthesis capacity and plant growth rate may. Various tools and methods (planimetry, leaf area meter, width-product, weight-area calculation, image processing programs, etc.) are used in determining leaf area. In this study, 3 American grape rootstocks (5BB, 110 R, 1103 P) and 5 grapes (Alphonse Lavallée, Italıa, Mıchele Palierı and Narince, Yalova İncisi) were used as material. 20 shoots with 15-25 nodules were taken from the rootstocks and varieties of the omca and the leaves were photocopied according to the order of the node. The actual field values of the leaves were measured with a planimeter. Leaf stem and leaf width and length of the leaves were also measured. Regression analysis was performed between leaf stem, leaf blade width and length, leaf blade × length values and real area. The maximum leaf area on one shoot was 5 BB (2484 cm2) from rootstocks and Narince (2126 cm2) from varieties. All three rootstocks gave the average value of the leaf found in 9th node. In terms of node number, which gives an average value according to the varieties, Alphonse Lavallée, Mıchele Palierı and Yalova İncisi varieties came to the forefront in 11th node. The 13th in Narince cultivar and the 12th in Italia cultivar gave the closest value to the average.

Seydahmet Cay | Serkan Sayin | Mehmet Soner Engin
In this study, we aimed to prepare new calixaren embedded mercapto groups supported liquid membranes and to use them in the transport of heavy metals. For this purpose 5,11,17,23-tetra-tert-butyl-25,27-bis(3-thiol-1-oxypropane)-26,28-dihydroxylcalix[4]arene was synthesized. The synthesized calixarene compounds were fully characterized by spectroscopic and the other techniques. The prepared compounds were supported polyamide liquid membranes and obtained calix[4]aren embedded supported liquid membranes (C@PSMs). The characterization of C@PSM was carried out by FTIR, TGA and elemental analysis techniques. Transport experiments were carried out with Pb(II), Cd(II) and Zn(II) as trace metals, to transport from donor phase to accept phase. From the results, it was calculated flux (J) and recovery (RF) values. The affinity (the percentage of metal ion transferred from the source solution) of a PIM towards a range of divalent cations was found to follow the order Zn(II)> Cd(II)> Pb(II).

Efficient use of water, one of the most critical life elements in the world, is becoming more and more important day by day. With the continuous increase in population and with climate change problems occur in terms of both consumption rate and usage patterns of water resources. It is becoming increasingly important to apply and research methods that can solve these problems all over the world. One of these solutions is the “Water Harvesting” method, which goes back many years. Water harvesting can be defined as the accumulation of runoff generated by precipitation to provide water for human, animal or crop use. While it is possible to see the use of the technique with roof and farm systems in micro-catchment dimension; wadi-bed and off-wadi (diversion) systems are used in macro-catchment dimension. In agricultural production, which uses a significant part of water resources, most of the rainwater falling into arid and semi-arid regions where production continues, goes away before could using efficiently by evaporation or flow. For this reason, the use of water resources becomes mandatory by using traditional irrigation methods in agricultural lands. With the water harvesting technique, after storing rain water, it can be held to be applied to crops. Hence the method since there will be no losses due to evaporation or flow, it will increase the total amount of irrigation water and reduce the pressure on water resources. Except for the protection of water resources, its role in preventing soil erosion is also seen as one of the main benefits of the method. In general, when the appropriate method is selected according to the appropriate geography, water harvesting has low inputs and is not difficult to apply. With a few exceptions, it does not require the use of pumps or energy input to deliver or deliver harvested water. In this study, information is given about the main elements, different usage areas and techniques of water harvesting.
Afficher plus [+] Moins [-]Effects of Zinc Sulphate Used as an Elicitor on Superoxide Dismutase, Peroxidase and Total Phenolic Compounds of Pepper Calluses

Cemil İşlek | Bengü Türkyılmaz Ünal | Sinan Aydın
The amount of secondary metabolites can be increased with different elicitor applications in vitro. It has been determined that zinc sulphate significantly increases the amount of capsaicin in the cell culture of red hot pepper. It is important to determine how the metal applied as elicitor will have an effect on plant metabolism. In the study, it was aimed to determine the effects of zinc sulphate (ZnSO4) applied to the cell suspension cultures of pepper seeds at different concentrations (0.1 M, 0.2 M, 0.4 M) and for periods (24, 48, 72 hours) on the total protein and phenolic substance amounts, and superoxide dismutase-peroxidase enzyme activities of pepper calluses. It was observed that the amount of protein increased, superoxide dismutase and peroxidase enzyme activities decreased, and the total amount of phenolic substance increased especially in 72 hours of treatment where zinc was applied as elicitor. These results show that ZnSO4 can be used as an abiotic elicitor in plant cell culture media.
