SOME BIOLOGICAL PECULIARITIES AND ECONOMIC VALUE OF THE CULTIVATION OF CUP PLANT, SILPHIUM PERFOLIATUM L.

Victor ȚÎȚEI, Natalia CÎRLIG, Ana GUŢU

Abstract


This article describes some peculiarities of the growth and development of the 'Vital' cultivar of Silphium perfoliatum L. and the advantages of its cultivation under the climatic conditions of the Republic of Moldova. It has been found that cup plant, in the second and the following years, has a growing season of 197-234 days, blooms and bears fruit, producing viable seeds. The flowering stage is long and staggered, thus, cup plant is a good source of pollen and nectar for bees and other insects. The aerial phytomass has high economic value as fodder for animals and as substrate for the production of renewable energy.

 

UNELE PARTICULARITĂȚI BIOLOGICE ALE SPECIEI SILPHIUM PERFOLIATUM L. ȘI VALOAREA EI CULTURALĂ

În lucrare sunt descrise unele aspecte ale creșterii și dezvoltării speciei Silphium perfoliatum L., soiul 'Vital', fiind specificată valoarea economică a acesteia în condițiile climatice ale Republicii Moldova. S-a stabilit că în anul doi și în următorii ani de creștere plantele de silfie au o perioadă de vegetație de 197-234 zile, înfloresc și fructifică, formând semințe viabile. Perioada de înflorire este îndelungată, eșalonată, asigurând o sursă de polen și nectar pentru albine și alte insecte. Fitomasa aeriană are valoare economică ca furaj pentru animale și ca substrat pentru obținerea energiei renovabile.


Keywords
