Definition of epicormic in English:


Pronunciation /ˌepiˈkôrmik/ /ˌɛpɪˈkɔrmɪk/


  • (of a shoot or branch) growing from a previously dormant bud on the trunk or a limb of a tree.

    ‘Analysis of height vs. diameter ratios among different tree subgroups, with and without epicormic branching, suggested that trees with epicormic branches generally have a low level of secondary growth compared with primary growth.’
    • ‘These buds may have developed into plagiotropic branches or orthotropic epicormic shoots.’
    • ‘Analyses were performed in duplicate on each of the 12 radiata trees that developed epicormic shoots and were used as the plant material source.’
    • ‘In older wood, epicormic shoots often result from severe defoliation or radical pruning.’
    • ‘In some species these buds can persist for years and even decades, but with damage or altered environmental conditions, hormonal changes can induce the development of the epicormic buds into new branches.’


Late 19th century from epi-‘upon’ + Greek kormos ‘tree trunk’.
