Cutting Baldcypress off at the knees

2010 | Michael Arnold, Texas A&M University

Baldcypress, Taxodium distichum (L.) Rich is a popular ornamental tree with excellent ornamental features and tolerance to urban/suburban environments.  However, the tendency for this species to develop knees is highly unpredictable among genotypes and environments.  The proposed research would facilitate the development of clonally produced baldcypress trees with reduced propensities to grow knees in urban and suburban environments.  The objective of the work proposed herein is to test a screening protocol for determining clonal baldcypress’ propensity to develop knees as young plants to aid the goal of developing “kneeless” baldcypress trees.
