Abstract EN

The research was conducted in a private nursery at Basrah governorate during 1 / 10 / 2011 – 1 / 5 / 2012 to study the effect of spraying with Benzyl Adenine (BA) at five concentrations (0, 10, 15, 20, and 25 mg / l) on vegetative growth and flowering of Snapdragon plant.

Results showed that treating plant with BA significantly increased vegetative growth indicators such as plant height, stem diameter, number of branches per plant, number of leaves per branch, leaf length, percentage of dry matter of leaf, leaf content of phosphorus, potassium and protein and (C / N) ratio in leaves.

Results also showed that there were significant increases in flowering parameters (number of flowers per stalk, flower stalk length, flower stalk diameter, vase life, percentage of dry matter of flower stalk, percentage of total soluble carbohydrates content in flower stalk and flower stalk content of nitrogen, phosphorus and potassium) when spraying with BA, meanwhile, flowering date was delayed as the concentration of BA increased.

The study concluded that treating with BA at the concentrations of 20 or 25 mg/l.

improved vegetative growth and flowering parameters.
