Bud development in corydalis (Corydalis bracteata) requires low temperature: a study of developmental and carbohydrate changes.

abstract：BACKGROUND AND AIMS:The success of using bent shoots in cut-rose (Rosa hybrida) production to improve flower shoot quality has been attributed to bent shoots capturing more light and thus providing more assimilates for flower shoot growth. We aimed at quantifying this contribution of photosynthesis by bent shoots to fl...
