The Effects Of Storage Periods On Some Quality Features Of Various-Sized Potato Varieties, Kemalleti̇n Kara
The Effects Of Storage Periods On Some Quality Features Of Various-Sized Potato Varieties, Kemalleti̇n Kara
Turkish Journal of Agriculture and Forestry
In this study, the effects of storage periods on some quality features of various dimensioned potatoes types were examined (2.5-5.0 cm, 5.0-6.5 cm and greater than 6.5 cm). The effects of storage duration on all properties except for the dry matter content were statistically significant. It was observed that with the extension of storage period, weight gain of the tubers decreased, and the other properties were not stable. There was no statistical significance among the tuber sizes in terms of specific weight, dry matter, the ratio of starch and protein and chip productivity, but weight loss and fat absorption ratio …

Turkish Journal of Agriculture and Forestry
The salt tolerance of some barley genotypes and their cross populations were evaluated at seedling stage in a greenhouse, and at the generative stage in a saline field in line x tester analysis. Promising crosses were determined through comparison of heterotic effects. Tokak-157/37 x LIGNEE-640, Quantum x MENTA "S" and Kaya-7794 x MENTA "S" were found to be superior cross combinations with respect to salt tolerance in both greenhouse and field conditions. In the cross populations, the highest- positive heterosis values were 25.00% for seedling emergence, 26.53% for root length, 66.27% for shoot length to root length ratio, 9.39% for …

Effects Of Wheel Traffic Porosity And Compaction Of Soil Profile, Cevdet Şeker, A. Ali̇ Işildar
Effects Of Wheel Traffic Porosity And Compaction Of Soil Profile, Cevdet Şeker, A. Ali̇ Işildar
Turkish Journal of Agriculture and Forestry
The aim of this experimental study was to determine the effect on soil porosity and compaction of the number of the tractor passes on the soil surface. The soil has a sandy loam texture. A tractor passed once, twice, and four times while the water content of soil was near field capacity. Numbers of tractings increased soil bulk density and compaction, and decreased total porosity, void ratio, air porosity and drainage porosity. One and two tractor passes did not markedly affect the percentage of porosity kept at field capacity porosity, but four tractor passes improved it.

Herbicide-Induced Resistance To Fusarium Wilt In Cotton And Gossypol Production Of Host Cells, Yeter Canihoş, Şener Kurt, Hülya Özgönen
Turkish Journal of Agriculture and Forestry
Pretreating cotton seeds with some herbicidies used in cotton-growing areas of the Çukurova region markedly increased cotton resistance to Fusarium wilt caused by Fusarium oxysporum f. sp. vasinfectum. Haloxyfob and linuron reduced the mycelial growth of the pathogen in both solid and liquid cultures. However, prometryn was more effective in plant development than linuron and haloxyfob. Synthesis of Phytoalexin gossypol was significantly produced in inoculated cotton plants compared with uninoculated control plants. Maximum amounts of gossypol production were obtained in herbicide-treated and inoculated cotton plants. Gossypol extracted from herbicide-treated plants markedly reduced the mycelial growth of the pathogen in vitro.

Turkish Journal of Agriculture and Forestry
The effect of the skin-contact on the composition of free and glycosidically bound aroma components of the must of Vitis vinifera cv. Emir was investigated. Aroma components were analysed by GC-MS. Seventeen free (3 six-carbon alcohols, 2 terpenols, 2 alcohols, 5 acids, 3 phenols, 2 C-13 norisoprenoids) and 30 bound aroma components (3 six-carbon alcohols, 4 terpenols, 5 alcohols, 5 acids, 9 phenols, 4 C-13 norisoprenoids) were identified. The skin-contact treatment increased amounts of free and glycosidically bound aroma components, potassium, total phenolic compounds and the browning index and the pH value, whereas it decreased the amount of total acidity.
