Turkish Journal of Agriculture and Forestry
Stem rust, caused by the fungus Puccinia graminis f. sp. tritici (Pgt), is one of the most important diseases limiting wheat production in Turkey. Surveys were conducted in 2007 and 2008 in order to determine the races of the pathogen present in Turkey. In 2007, it was found that 91 (43%) out of 207 inspected wheat fields were infected with stem rust, and in 2008, it was found that 61 (25%) out of 242 inspected fields were infected. From these samples, 40 single pustule isolates were obtained. The North American differential set, which includes 20 genotypes with different resistance genes, …

Turkish Journal of Agriculture and Forestry
The rootstock potential of 21 bottle gourds (Lagenaria siceraria) collected from the Mediterranean region (Turkey) was investigated for watermelon with regard to plant growth, yield, and fruit quality. The Crimson Tide watermelon cultivar was used as a scion and 2 commercial rootstocks (L. siceraria) were also used for comparison. In greenhouse conditions, the survival rate of grafted plants and the effect of rootstocks on plant growth were determined. The grafted plants were planted under low tunnels in early spring and the effects of the rootstocks on early yield, total yield, and fruit quality were evaluated. The survival rates of the …

Turkish Journal of Agriculture and Forestry
Boron efficiency of 16 oilseed rape genotypes was tested using both hydroponic and pot-soil growing techniques. From the nutrient solution experiment (0.1 and 10 µM B), 4 representative contrasting genotypes were selected based on relative root and shoot growth. These were then grown in pots with low-B soil (0.25 mg kg^{-1}). From the nutrient solution experiment, 2 genotypes selected as B-inefficient did not show any growth disorders, and the concentration of B in the shoots was above critical. Furthermore, 4 contrasting genotypes were subjected to the stable 11B isotope-enriched uptake solution for 6 h to verify possible low B-induced active …

Seed Priming With Antioxidants Improves Sunflower Seed Germination And Seedling Growth Under Unfavorable Germination Conditions, Ivana Draganic, Slavoljub Lekic
Turkish Journal of Agriculture and Forestry
The results of studying the effects of sunflower seed priming with an aqueous solution of ascorbic acid (A), tocopherol (T), and glutathione (G) performed prior to accelerated ageing and a cold test are presented in this paper. Germination, the percentage of abnormal seedlings, and the lengths of both roots and shoots were monitored. The results showed that the cold test caused a drastic drop in germination, an adverse effect on the shoot length, an increase in the percentage of abnormal seedlings, and no effect on the root length. Germination of seeds primed with the solution of A, T, and G …

Combined Treatment Of Modified Atmosphere Packaging And 1-Methylcyclopropene Improves Postharvest Quality Of Japanese Plums, Mustafa Erkan, Hakan Eski̇
Turkish Journal of Agriculture and Forestry
Two Japanese-type plum (Prunus salicina Lindell) cultivars, 'Autumn Giant' and 'Black Beauty', were harvested at commercial maturity stage and either packed in nonperforated modified atmosphere packaging (MAP) or treated with a 500 ppb dose of 1-methylcyclopropene (1-MCP) alone or given a combination of 1-MCP and MAP. After these treatments, the plum samples were stored at 0 °C for 60 days. Treatment with either 1-MCP or modified atmosphere packaging (MAP) alone or with the 1-MCP+MAP combination reduced fruit softening, ethylene production, respiration rate, weight loss, and flesh browning, and resulted in higher flesh firmness, titratable acidity, and total soluble solids as …

Seeds of 14 commonly found plant species from 3 different families (Brassicaceae, Dipsacaceae, and Asteraceae) were investigated for 1000-seed weights (g), total oil (%), total protein (%), total soluble sugar contents (TSS; mg g^{-1}), and fatty acid compositions (%). Correlation coefficients of fatty acids from different families were investigated, as well. Palmitic, stearic, oleic, linoleic, linolenic, eicosenoic, and erucic acids were present in varying amounts. Within the family Brassicaceae, only Cardaria draba did not contain eicosenoic and erucic acids, while species of the Asteraceae and Dipsacaceae did not contain linolenic, eicosenoic, or erucic acids.

Effect Of Al Compounds On Soil Ph And Bioavailability Of Al In Two Acid Soils, Toufiq Iqbal
Turkish Journal of Agriculture and Forestry
Two aluminum compounds, AlCl_3 and Al(OH)_3, were used to determine the effect of Al compounds on pH and bioavailability of Al in 2 acid soils. Both soils were incubated for periods of 3, 10, and 30 days. Al-tolerant (ET8) and Al-sensitive (ES8) wheat seedlings were used as a testing plant to confirm bioavailability of Al^{3+} in soil solution. Both soils were acidified through the addition of Al compounds to detect the maximum Al^{3+} toxicity level of these compounds. The results showed that the AlCl3 compound increased the bioavailability of Al^{3+} in soil solutions. In contrast, AlCl_3 decreased bulk soil pH. …

Turkish Journal of Agriculture and Forestry
Moringa oleifera is a miracle tree that can be used in multiple ways, including as foodstuff, livestock fodder, a plant growth enhancer, or a water purifier. While the stem cutting method is easy and successful for tree propagation, the recent introduction of moringa as a field crop for biomass production requires propagation through seeds. The germination of stored moringa seeds is a problem of great concern that may be overcome by employing seed priming techniques. A pot study was conducted to explore the potential of seed priming in moringa. Seeds were subjected to hydropriming, matripriming, and priming with moringa leaf …

Maintaining and increasing biodiversity level especially in pure plantations is one important way to improve the resistance of forests to pests in Chinese boreal forests. The present study tested the hypothesis that the increased degree of tree species mixture (quantified by the stem proportion of Betula platyphylla Suk. and Larix gmelinii (Rupr.) Rupr.) can affect the species richness and diversity of understory and insects. Twenty-one plots, ranging from pure larch stand to pure birch stand, were sampled in several thinned forests in a Chinese boreal forest area. Data of environmental factors, understory plant species and insect assemblage were collected from …

Seedling Root Morphology Of Six Alfalfa Populations, Brianna J. Gaughan
The Journal of Undergraduate Research
Seedling root morphology plays a crucial role in seedling survival and stand establishment. Naturalized yellow-flowered alfalfa (YFA) (Medicago sativa subsp. falcata) has demonstrated adaptation to semiarid conditions of the Northern Great Plains and tolerance to grazing. Seedling stage root morphology is poorly defined. Our objective was to compare morphological traits of seedling roots for six alfalfa populations. Six entries were evaluated: one M. sativa population as a control, two M. falcata entries, with reported “spreading characteristics” and three naturalized YFA populations. Uniform seeds of each entry were scarified with 320 grade sand paper and inoculated with rhizobium before planting. A …
