Seed quality, and fatty acid and sugar contents of pepper seeds (Capsicum annuum L.) in relation to seed development and drying temperatures
Öz: Bu çalışmada, biber tohumlarının (Capsicum annuum L.) tohum çimlenmesi ve tohum gücü ile toplam yağ asitleri ve şeker içeriği (sukroz, glikoz, fruktoz) üzerine, farklı gelişme devrelerinin (55, 65, 75 ve 85 DAA-Çiçeklenmeden Sonraki Gün Sayısı) ve kurutma sıcaklıklarının (25, 35 ve 45 °C) etkisi belirlenmiştir. Elde edilen sonuçlara göre, tohumların çiçeklenmeden sonra 75. gün ve sonrası hasat edilmeleri şartıyla 45 °C’ye kadar çıkan sıcaklıklarda kurutulmaları halinde tohum kalitesinde (canlılık ve güç) olumsuz bir etkiye rastlanmamıştır. Biber tohumlarında toplam yağ asitlerinin % 75-80’ini linoleik asit (18:2) oluşturmuştur. Bunu yaklaşık % 10-12 ile oleik (18:1) ve palmitik (16:0) asitler ve de % 3 ile stearik (18:0) asit izlemektedir. Çalışmada, farklı sıcaklıklarda kurutulmuş tohumların yağ asitleri içeriği benzer bulunmuştur. Fruktoz ve glikoz gelişme dönemi ilerledikçe azalmaya başlamakta ve son hasatta toplam şekerin % 4’ünden de düşük seviyeye inmektedir. Her iki yılda da, 45 °C’de kurutulan tohumların şeker kapsamı, 25 ve 35 °C’de kurutulan tohumlardan daha düşük seviyede olmuştur. Sonuç olarak, biberde tohumlar çiçeklenmeden sonra 75. günde hasat edilmek kaydıyla, 25 ve 45 °C arasındaki kurutma sıcaklıkları tohum kalitesi, yağ asidi ve sukroz bileşimini etkilememektedir.

Öz: This study was carried out in order to determine the effects of drying temperature (25, 35, and 45 °C) and the developmental stage (55, 65, 75, and 85 days after anthesis (DAA)) on germination, vigor, and the sugar (sucrose, glucose, fructose) and fatty acid contents of pepper seeds (Capsicum annuum L.) over 2 consecutive years. In seeds harvested at 75 DAA and after, seed viability and vigor were not influenced by drying at temperatures up to 45 °C. Linoleic acid (18:2) was the main fatty acid in pepper seeds, comprising 75-80% of total fatty acids. It was followed by oleic (18:1) and palmitic (16:0) as roughly 10%-12% and stearic (18:0) as 3%. The results indicated that drying seeds at different temperatures does not change fatty acid composition. Approximately 30% of the pepper seeds are constituted of sucrose, and this did not change with maturity level between 55 and 85 DAA, nor did it change at different drying temperatures. However, the levels of fructose and glucose gradually decreased as the developmental stage advanced and both were lower than 4% of total sugar at the final harvest. Seeds dried at 45 °C had lower amounts of sugar compared to those dried at 25 and 35 °C. Seed quality and fatty acid and sucrose composition do not change as long as the seeds are harvested within 75 DAA.
