In this study, the effects of moisture content on some of physical properties of madimak (Polygonum cognatum Meissn.) seeds were investigated. Moisture contents of seeds were 7.95, 13.68 and 19.14% d.b. (dry basis), respectively. The average geometric mean diameter, unit mass, sphericity, thousand-seed mass and angle of repose ranged from 1.85 to 1.94 mm, 0.0040 to 0.0046 g, 66.21 to 67.37%, 3.32 to 3.74 g and 18.36 to 25.00° as the moisture content increased from 7.95 to 19.14% d.b., respectively. Bulk density and porosity were decreased from 696.11 to 707.73 kg m-3, 57.93 to 40.16%, whereas the seed volume, true density and surface area were increased from 3.357 to 3.894 mm3, 1654.69 to 1182.64 kg m-3, and 10.786 to 11.867 mm2 as the moisture content increased, respectively. The static coefficient of friction on various surfaces linearly increased with an increase in moisture content. Since madimak seeds are in small sizes, they can easily be separated at higher moisture contents which will also help planting of small seeds and enhance germination rate.
Bu çalışmada, madımak (Polygonum cognatum Meissn.) tohumunun bazı fiziksel özelliklerine nem içeriğinin etkisi belirlenmiştir. Nem içerikleri sırasıyla %7,95; 13,68 ve 19.14 (kuru baza göre) olarak belirlendi. Ortalama geometrik ortalama çap, birim ağırlık, küresellik, 1000 dane ağırlığı ve doğal yığıılma açısı nem içeriğinin %7,95’den %19.14’e kadar artışına göre sırasıyla 1,85’den 1.94 mm’e, 0,0040’dan 0.0046 g’a, %66.21’den 67.37’e, 3,32’den 3,74 g’a kadar ve 18,36’dan 25,00°’ye kadar değişiklik göstermiştir. Tohum hacmi, yığın hacim ağırlığı ve yüzey alanı değerleri nem içeriği artışına göre; 3,357 mm3’den 3,894 mm3’e, 696,11 kg m-3’den 707,73 kg m-3’e ve 10,786’dan 11,867 mm2’ e artış gösterirken, tane hacim ağırlığı ve porozite değerleri; %57,93’den %40,16’a 1654,69 kg m-3’den 1182,64 kg m-3’e azalmıştır. Statik sürtünme katsayısı değerleri, farklı yüzeyler için nem içeriği artışıyla artış göstermiştir. Madımak tohumları çok küçük boyutlarda olduğu için yüksek nem içeriklerinde kolayca ayrılabilir, dolayısıyla bu küçük tohumların ekimini ve çimlenme oranının artışına yardımcı olabilir.
