Farklı Yumrulu Kanyaş (Phalaris aquatica L.) Genotiplerinde Kurutma İşleminin Alkaloid İçeriğine Etkileri

Öz

Bu çalışma 6 farklı yumrulu kanyaş (Phalaris aquatica L.) genotipinin (Pa-5, Pa-9, Pa-15, Pa-17, Surocco ve Sirosa) alkaloid içeriğini belirlemek ve kurutma işleminin bu bileşikler üzerindeki etkilerini incelemek amacıyla yürütülmüştür. Yaş ve kuru örneklerde HPLC cihazı kullanılarak Gramine, Hordenine, 5-methoxy-tryptamine ve β-karbolin bileşikleri belirlenmiştir. En yüksek toplam alkaloid içeriği Sirosa genotipinin yaş, en düşük ise Pa-17 genotipinin kuru örneğinde saptanmıştır. Kurutma işlemi çoğu genotipte alkaloidleri düşürürken, bazı örneklerde artış gözlenmiştir. Elde edilen bulgular, kaliteli kaba yem üretimi için genotipe özgü kurutma protokollerinin belirlenmesinin ve düşük alkaloid içeriğine sahip genotiplerin seçiminin önemini göstermektedir.

Effects of the Drying Process on Alkaloid Content in Different Bulbous Canary Grass (Phalaris aquatica L.) Genotypes

Öz

This study determined the alkaloid content of six tuberous canary grass (Phalaris aquatica L.) genotypes (Pa 5, Pa 9, Pa 15, Pa 17, Surocco, Sirosa) and examined the effects of drying on these compounds. Gramine, hordenine, 5 methoxy tryptamine and β carboline were quantified by HPLC in fresh and dried samples. The highest total alkaloid content was in fresh Sirosa, the lowest in dried Pa 17. While drying reduced alkaloids in most genotypes, some showed increases. These findings underscore the need for genotype specific drying protocols and selecting low alkaloid genotypes for high quality forage production.
