Indigofera zollingeriana'nın Tohum Çimlenmesinde Ön İşlem Etkisinin İyileştirilmesi

Abstract

Indigofera zollingeriana is one of Indigofera species distributed in Indonesia and known as forage crop. Seed is an important factor which influences cultivation of I. zollingeriana due to low seed germination. The objective of the research was to determine the effect of different pre-treatment as chemical scarification (98% of H2SO4, 0.3% of KNO3, glycerine (C3H8O3) at 70 o C), hot water at 70 o C with different duration of immersion or soaking and mechanical scarification using sand paper on I. zollingeriana's seed germination. Pretreatment had significant differences and improved germination percentage, germination speed index and shoot length. The positive correlation was noted between germination percentage and germination speed index.
