Germination of Corylopsis seeds evaluated by X-ray imaging and cold stratification [PDF]

open access: yesHorticultural Science, 2017
Effects of immersing seeds in water and X-ray imagining on germination of Corylopsis seed were investigated. Seeds that sank or floated were collected after immersing in water for 5 min, 4 h or 16 h, and germinated with or without 5°C cold stratification (CS). In C. coreana and C. sinensis var.
