Abstract

Depulped seeds of Liriope muscari (Decne.) L. H. Bailey pretreated with GA3 and/or kinetin and placed at 21°C for warm stratification, showed increased germination over unpulped seeds. Germination rates ranged from 87 to 100%. Identical growth regulator treatments resulted in no germination when the depulped seeds were cold stratified (5°C). Unpulped seed, pre-soaked in water for 24 hours or not soaked and given warm stratification germinated 38 and 25%, respectively. This suggested that the inhibition in unpulped seed is influenced by a water soluble inhibitor in the fruit wall.
