The objective of this study was to establish the effects of chilling period and chilling temperature on germination in linseed (Linum usitatissimum L.). Seeds were subjected to six different heat temperatures (0, 2, 4, 6, 8 and 10 o C) for 24, 48, 72, 96, and 120 hours. Germination tests were carried out in a clammed chamber at 25 o C with 70% humidity, 8 hours dark and 16 hours light condition. In all varieties, germination was significantly affected by temperature chilling level. Average mean germination percentage was 88.50% and 93.77% for Antares and 83.24% for Bionda. Germination capacity of seeds was affected either by chilling period or chilling temperature. The highest germination percentage were 0 o C chilling temperature and 96 hours chilling period for Antares with 97.20% and 72 hours chilling period for Bionda with 90.80% germination percentage.

A split-plot design, with two varieties as the main plot and four sowing times as the subplot, was carried out over two growing seasons (2017–2019) in Samsun, Turkey. Sequential path analysis revealed that, as first-order predictors, grain yield and oil content displayed the most significant and positive direct effects on oil yield in both summer and winter cultivation. The sequential path analysis of second-order variables over the first-order variable revealed that seed number per pod and pod number explained approximately 90% of the variation of the grain yield in summer cultivation and branch number explained approximately 67% of the variation grain yield in winter cultivation. These results in...

The present study was conducted to produce simple regression models to predict how temperature affects the time it takes for 50% of a selection of flax seeds to germinate. R-square (r 2) values of regression coefficients of the equations established for flax cultivars varied from 0.899 (Antares) to 0.886 (Bionda). The optimum temperature for the time to germination for both cultivars was calculated using the coefficients obtained from the regression models. The optimum temperatures were found to be between 22.10 and 22.05 °C for Antares and Bionda, respectively.

Depending on the sowing time, the change of oil content and main fatty acids such as palmitic, stearic, oleic, linoleic, linolenic eicosenoic and erusic acid content is 26.65-33.65%, 6.04-7.08%, 2.04-3.15%, 16.63-18.84%, 24.51-25.16%, 29.57-31.69%, 14.30-15.04% and 1.10-1.86%, respectively. When the sowing time is delayed; oil content, stearic, linoleic, linolenic and erusic acid content decreased in contrast palmitic, oleic and eicosenoic acid content increased. The effect of sowing time on genotypes is important in terms of the evaluated characters. The PI-650142 genotype is more tolerant than PI-304269 genotype against the effects of environmental factors. Consequently, in case of delay of sowing time, it is extremely important to perform timely sowing, considering the changes in both oil content and fatty acids c...

This study investigated the laying performance and several egg quality characteristics in layer hens fed on a conventional diet with free access to a soil area (control, C), a chicory (CI)- or white clover (TR)-vegetated area, or a CI and TR mixture (MIX)-vegetated area. The C hens consumed more concentrate feed, without affecting the laying rate, than did TR and MIX hens. Herbage intake (HI) of the TR and MIX hens was higher than that of the CI birds. The C hens produced eggs with thicker shells than the CI, TR, and MIX hens. The decrease in the feed intake and the improvement in fatty acid (FA) profiles of the egg yolk was related to the HI. Concerning the TR and MIX vegetation, the FA composition of herbage contributed to the production of eggs with preferred FA attributes, such as polyunsaturated FAs and a favourable n-6 to n-3 ratio. Abstract This study investigated the laying perf...

Çeşitlerin çimlenme oranı Balcı çeşidinde %58,7 ve Dinçer çeşidinde %53,6 olduğu belirlenmiştir. Çimlenme sıcaklıklarına göre aspirde çimlenme oranının %35,3 ile %71,7 arasında değiştiği, en yüksek çimlenme oranının 16°C sıcaklıkta elde edildiği belirlenmiştir. Çeşit x çimlenme sıcaklığı interaksiyonu bakımından değerlendirildiğinde en yüksek çimlenme oranının %76,2 ile Balcı çeşidinden 16°C çiml...

Tarihin en eski bitkilerinden biri olan kenevir, ilaç, gıda, kâğıt, biyoyakıt, tekstil, kozmetik, inşaat ve otomotiv sektörüne kadar oldukça geniş yelpazede kullanım alanına sahiptir. Ekolojik ve topografı istekleri bakımından kanaatkâr bir bitki olan kenevirin adaptasyon kabiliyeti geniştir. Kenevir tohumu yaklaşık %35 yağ ve %25 protein içermesinin yanında Omega-3 kaynağı olarak da zengindir. Endüstriyel kenevir, kaliteli lif kaynağı özelliği sayesinde yakın zamanda geniş ekim alanlarında yer bularak endüstriye önemli ölçüde katkı sağlayacak potansiyele ulaşmıştır. Narkotik özelliklerinden dolayı birçok ülkede olduğu gibi ülkemizde de yasaklanan geleneksel kenevirin aksine son yıllarda geliştirilen endüstriyel amaçlı kenevir çeşitleri sayesinde kenevir tarımı birçok ülkede her geçen gün genişlemekte ve ülkelerin ekonomilerine önemli katkı sağlama potansiyeli arz etmektedir.

Two safflower cultivars named Balci and Dincer were used as material. In the study, eight germination temperatures of 8, 12, 16, 20, 24, 28, 32 and 36°C were applied at 4°C intervals. The result of the research showed that the germination rate of both varieties was affected significantly by temperatures, the overall mean germination rate was determined as 56.1%. When evaluated in terms of variety; germination rate was 58.7% for Balci and 53.6% for Dincer. When evaluated in terms of germination temperature; germination rate ranged from 35.3% to 71.7%, the highest germination rate was obtained at 16°C. Variety × germination temperature is evaluated in terms of interaction; highest germination rate of 76.2% with 16°C germination temperature was obtained from Balci variety. In addition, the relationship between germination temperature and germination ...

Depending on the sowing time, the change of oil content and main fatty acids such as palmitic, stearic, oleic, linoleic, linolenic eicosenoic and erusic acid content is 26.65-33.65%, 6.04-7.08%, 2.04-3.15%, 16.63-18.84%, 24.51-25.16%, 29.57-31.69%, 14.30-15.04% and 1.10-1.86%, respectively. When the sowing time is delayed; oil content, stearic, linoleic, linolenic and erusic acid content decreased in contrast palmitic, oleic and eicosenoic acid content increased. The effect of sowing time on genotypes is important in terms of the evaluated characters. The PI-650142 genotype is more tolerant than PI-304269 genotype against the effects of environmental factors. Consequently, in case of delay of sowing time, it is extremely important to perform timely sowing, considering the changes in both oil content and fatty acids c...

This study investigated the laying performance and several egg quality characteristics in layer hens fed on a conventional diet with free access to a soil area (control, C), a chicory (CI)- or white clover (TR)-vegetated area, or a CI and TR mixture (MIX)-vegetated area. The C hens consumed more concentrate feed, without affecting the laying rate, than did TR and MIX hens. Herbage intake (HI) of the TR and MIX hens was higher than that of the CI birds. The C hens produced eggs with thicker shells than the CI, TR, and MIX hens. The decrease in the feed intake and the improvement in fatty acid (FA) profiles of the egg yolk was related to the HI. Concerning the TR and MIX vegetation, the FA composition of herbage contributed to the production of eggs with preferred FA attributes, such as polyunsaturated FAs and a favourable n-6 to n-3 ratio. Abstract This study investigated the laying perf...
