This study was conducted to determine some physicochemical and mineral compositions of mulberry

fruit at different harvest dates during a harvest season. The study was carried out on 25-year-old mulberry trees

belonging to Morus alba L. cultivated in an orchard in Upper Coruh valley of Turkey in 2005 and 2006. Fruit size,

total soluble solid (TSS), fruit dry yield (FDY), color (L, a, b) of fruits varied between 2.32-3.18 g, 24.07-31.33%,

27.10-31.33%, 36.41-51.74, 4.42-8.20, 23.66-28.42, respectively. As the mineral compositions of mulberry fruit,

3.10-3.36 g 100g-1 N, 0.298-0.417 g 100g-1 P, 1.82-2.12 g 100g-1 K, 2.63-2.93 g 100g-1 Ca, 0.593-0.723 g 100g-1 Mg,

0.180-0.325 g 100g-1 S, 63.7-71.2 mg kg -1 Na, 114.3-126.3 mg kg -1 Fe, 69.8-76.8 mg kg -1 Mn, 29.0-36.2 mg kg -1

Zn, and 11.2-17.2 mg kg -1 Cu were determined. As a result, TSS, FDY, K, Ca, Mg, S and Zn minerals of the fruit

were determined to increase towards the end of the harvest season.

Farklı Hasat Dönemlerinde Dut Meyvelerinin Fizikokimyasal ve Mineral Madde İçeriklerinin Belirlenmesi

Öz

Bu çalışmada bir hasat sezonu boyunca farklı tarihlerde hasat edilen dut meyvelerinin bazı fizikokimyasal

ve mineral içerikleri belirlenmiştir. Çalışma yukarı Çoruh vadisinde 2005-2006 yıllarında 25 yaşlı dut ağaçlarında

yürütülmüştür. Meyve ağırlığı, SÇKM, kuru randıman, renk (L,a,b) ölçüm değerleri sırasıyla 2.32-3.18 g, %24.07-

31.33 g, %27.10-31.33, 36.41-51.74, 4.42-8.20, 23.66-28.42 arasında değişim göstermiştir. Dut meyvelerinin

mineral madde içerikleri ise 3.10-3.36 g 100g-1 N, 0.298-0.417 g 100g-1 P, 1.82-2.12 g 100g-1 K, 2.63-2.93 g 100g-1

Ca, 0.593-0.723 g 100g-1 Mg, 0.180-0.325 g 100g-1 S, 63.7-71.2 mg kg -1 Na, 114.3-126.3 mg kg -1 Fe, 69.8-76.8 mg

kg -1 Mn, 29.0-36.2 mg kg -1 Zn, 11.2-17.2 mg kg -1 Cu arasında belirlenmiştir. Çalışma sonucunda, hasat sezonunun

sonuna doğru meyvelerin SÇKM, kuru randıman değerleri ile K, Ca, Mg, S ve Zn gibi mineral içeriklerinin arttığı

tespit edilmiştir.
