Abstract
Soğan (Allium cepa L.), ülkemizde ticari anlamda ön plana çıkan önemli bitkilerden birdir. Geniş alanlarda mekanizasyon uygulamaları ile daha kaliteli tohum üretimini arttırmak amacıyla çeşitli çalışmalar yapılmaktadır. Tohum uygulamaları (film kaplama ve pelletleme) özellikle amorf, hafif ve küçük boyuttaki tohumları büyük, ağır, pürüzsüz bir yüzeye ulaşmasını sağlamak amacıyla yapılmaktadır. Bu çalışma da, soğan tohumuna ait(uygulama öncesi ve sonrası) bazı fiziksel (şekil, boyut, yüzey alan, bin tane ağırlığı) ve mekanik (statik ve dinamik sürtünme katsayısı) özellikler belirlenmiştir. Tohum uygulamalarının ardından soğan tohumun fiziksel özelliklerinin yaklaşık 1,5 kat büyüdüğü ve bin dane ağırlığının yaklaşık 2,5 kat arttığı saptanmıştır. Tohumların mekanik özellikleri bakımından, taşıma ve depolama için kullanılan farklı yüzeylerdeki davranışları incelenmiş ve tohum uygulamaları sonrasında bu yüzeylerdeki değişimin istatistiki olarak önemli farklılıklara neden olduğu ortaya konmuştur.
The onion (Allium cepa L.) is one of the most important plants in the commercial sense in our country. Several studies have been done to increase the production of better quality seeds and mechanization practices on large areas. Seed treatments (film coating and pelleting) are carried out in order to ensure that seeds, especially in amorphous, light and small size, reach a large, heavy, smooth surface. In this study, some physical (shape, size, surface area, thousand grain weight) and mechanical (static and dynamic friction coefficient) properties of seeds were determined after seed application. When the physical properties of the onion seeds on which the seeds were applied were examined, it was found that it grew about 1.5 times and the weight of thousand seeds increased about 2.5 times. In terms of mechanical properties of seeds, the behavior of different surfaces used for transportation and storage are examined. It was determined that the change in these surfaces caused statistically significant differences after seed application.
