Vacuolar status and water relations in embryonic axes of recalcitrant Aesculus hippocastanum seeds during stratification and early germination

Cells of embryonic axes in recalcitrant horse chestnut seeds are associated with a high water content and functionally preserved vacuoles with active aquaporins and invertase. These vacuoles function to the support rapid cell elongation of the hypocotyl that results in radicle emergence and thus the...

Summary:Cells of embryonic axes in recalcitrant horse chestnut seeds are associated with a high water content and functionally preserved vacuoles with active aquaporins and invertase. These vacuoles function to the support rapid cell elongation of the hypocotyl that results in radicle emergence and thus the start of visible germination.
