STUDIES ON THE INFLUENCE OF SOME REGULATING GROWING SUBSTANCES UPON THE QUANTITY AND QUALITY OF MENTHA PIPERITA PRODUCTION

Mentha piperita, an important medicinal plant due to its volatile oil content and especially its main component, menthol, is cultivated at present on small surfaces. Out of the wish to increase the production of mint we resorted to phyto-regulating growing substances. The biometric determinations were effectuated in the period on vegetative growth and the inflorescence phase. We followed the quantitative differences as compared to the blank test, for each more important vegetative organ and for the entire plant. In 2008, we studied the effect of some bio-regulating growing substances on mint. We noticed some substances with a benefic role upon the increase of mint production.
