Abstract

Mediterranean shrubs try to keep up their forage value year-round with their deep root penetrations and ever-green futures. Therefore, shrubs can serve a good source of nutrient for goats and may meet nutritional needs of goats. However, beside the nutrients, there are several other beneficial or harmful minerals in plants. This research was carried out in Marmara region of Turkey to investigate the amounts and variations of these kinds of elements. Variations of non-nutrient contents of shrubs and relevance with goats were evaluated. Experiments were carried out over two shrubby rangelands of Çanakkale province between the dates October 2006 and November 2007. Se, Co, Ni, Cr, Cd and Pb contents of kermes oak, mock privet, prickly juniper, gall oak, Christ’s-thorn, pink rockrose, thyme and prickly burnet shrubs were determined. Annual variations of most of the minerals were found to be significant but irregular. Irregularity in variations was due to the fact that these elements are not essential for plants and present at trace amounts. Se contents of shrubs varied between 0.02-0.45, Co between 0.01-46, Ni 1.70-5.54, Cr 1.35-2.29, Cd 0.01-0.15 and Pb 0.72-1.93 mg kg-1. None of these elements were found to be insufficient or redundant to create a problem either for plants or animals

Akdeniz iklim kuşağının yaygın çalılarında mineral element içeriklerinin değişimi: Diğer elementler

Abstract

Akdeniz kuşağı çalıları derin kökleri ve genelde herdem yeşil yapıları ile yem değerlerini yıl
boyu korumaya çalışırlar. Bu durum keçilerin besin elementi ihtiyaçlarının büyük bir bölümünü
buralardan karşılamalarına yardımcı olur. Ancak bitkilerde besin elementleri dışında yararlı ya
da zararlı olabilen birçok mineral de bulunmaktadır. Bu tür elementlerin çalılardaki miktarları
veya değişimleri konusunda Türkiye’nin Marmara ve Ege bölgelerinde araştırma
yapılmamıştır. Bu nedenle bu araştırmada besin elementi olmayan minerallerin çalılardaki
değişimi incelenmiş ve bunların keçilerle ilişkileri ortaya konmuştur. Deneme Ekim 2006 -
Kasım 2007 tarihleri arasında Çanakkale’nin iki ayrı çalılı alanında yürütülmüştür. Araştırmada
kermes meşesi, akçakesme, katran ardıcı, mazı meşesi, karaçalı, yapraklı laden, kekik ve
abdestbozan çalılarının Se, Co, Ni, Cr, Cd ve Pb miktarları belirlenmiştir. İncelenen çalılardaki
çoğu mineralin yıl boyu değişimi önemli, ancak düzensiz olmuştur. Bu düzensizlik genelde bu
elementlerin bitkiler için mutlak gerekli olmadıklarından ve eser miktarlarda bulunmalarından
ileri gelmiştir. Çalıların ortalama Se miktarları 0.02-0.45, Co 0.01-46, Ni 1.70-5.54, Cr 1.35-
2.29, Cd 0.01-0.15 ve Pb 0.72-1.93 mg kg-1 arasında değişmiştir. Bu elementlerin hiçbiri gerek
bitkiler gerekse hayvanlar için eksiklik veya fazlalık olarak herhangi bir sorun yaratacak
düzeyde olmamıştır
