A master's thesis in the Department of Horticulture and Landscape Engineering at the College of Agriculture at the University of Basra investigated the effect of spraying plant extracts and tryptophan on the growth of the Chasteberry plant.
The thesis, presented by graduate student Musa Kazim Ne'ma under the supervision of Professor Fatima Ali Hassan and Assistant Professor Thaer Yassin Khudair, aimed to determine the optimal concentration of the study factors to achieve the best yield.
The thesis included spraying plant extracts and tryptophan and their effects on the growth of the studied plant.
The thesis concluded that spraying with the amino acid tryptophan at a concentration of 200 mg/L, sweet seed at a concentration of 100 g/L, and sage leaf extract at a concentration of 50 g/L led to a significant increase in most vegetative and root characteristics, chemical characteristics, and volatile oil properties.
The thesis recommended that, given the plant's medicinal, therapeutic, and industrial importance, its successful cultivation, and its tolerance to high temperatures, multiple studies should be conducted to benefit from it.
