Study of hormonal & chemical composition of petroselinum hortense L. and the possibility to use in the applied field.

Abstract

Experiments designed to study the effects of 3 concentrations of each of indole butyric acid (25,50 and 100 ppm )and Mepiquat chloride (125,250 and 500 ppm ) on Petroselinum hortense L. extracts. The experiments were designed according to RCBD method and each treatment was replicated 3 times. Dunken test at level of 0.05 was used to compare the effect of treatments. Result showed that the percentage of active ingredients of the plant extracts (essential oil , coumarin, flavonoids,were significantly increase with increasing indole butyric acid compare with control treatment. However, application of Mepiquat chloride decreased them compare with control treatment. Indole butyric acid increased endogenous gibbereline acid and indole acetic acid while Mepiquat decreased them. This study proved that growth regulators of the plant as a natural tool to increase active ingredients for their medical value.
