Effect of ontogenic age on root and shoot development of Tabebuia heterophylla cuttings propagated in soilless culture

A study was conducted to evaluate the root and shoot development in cuttings of Tabebuia heterophyllataken from varying ages of stock plants (1, 6, 18, 36 and 60 months). Cuttings obtained from the mother plants were rooted on perlite in saturated propagation chambers for 60 days. Generations of new...
