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

Constanta Nicodim, C. Milica

Abstract
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.

Key words: bio-regulating growing substances, influence on production

STUDII PRIVIND INFLUENTA UNOR SUBSTANTE REGULATOARE DE CRESTERE ASUPRA CANTITATII SI CALITATII PRODUCTIEI DE MENTHA PIPERITA

Rezumat
Mentha piperita, o importanta planta medicinala datorita continutul de ulei volatil si īn special componentul principal al acestuia, mentolul, se cultiva in prezent pe suprafete mici. Din dorinta de a creste productia de herba la menta s-a apelat la substante fitoregulatoare de crestere. Determinarile biometrice s-au efectuat, īn perioada cresterii vegetative si īn faza īnfloririi. S-au urmarit la menta deosebirile cantitative fata de martor, pe fiecare organ vegetativ mai important, cāt si pe planta īntreaga. Īn anul 2008 s-a urmarit efectul unor substante bioregulatoare de crestere asupra mentei. Au fost remarcate unele substante cu rol benefic asupra cresterii productiei la menta.

Cuvinte cheie: substante bio-reglatoare de crestere, influenta productiva
