Abstract

Konoplja (Cannabis sativa L.) je jednogodišnja, zeljasta biljka iz porodice konoplji (Cannabaceae), roda Cannabis. Vrsta Cannabis sativa ima tri podvrste: Cannabis sativa L. ssp. sativa, Cannabis sativa L. ssp. indica, Cannabis sativa L. ssp. ruderalis. Porijeklom je iz središnje Azije. Industrijska konoplja (Cannabis sativa L.) se stoljećima proizvodi za dobivanje vlakna i sjemena.
Ciljevi ovog istraživanja su utvrditi mogućnost akumulacije teških metala iz tla korištenjem četiri sorte... More konoplje (Fedora 17, Fibrol, Futura 75 i Santhica 27) pri alkalnoj i kiseloj reakciji tla, te provjeriti hipotezu je li konoplja hiperakumulator teških metala.
Na usvajanje teških metala (Cd, Cu, Ni, Pb, Zn, Cr, Hg, Co, Mo i As) mjerenih u korijenu konoplje, stabljici i listu, u najvećoj je mjeri utjecala reakcija tla (pH). Temeljem ovog istraživanja utvrđeno je da se sorta Fibrol može koristiti za uklanjanje teških metala iz tla. Nadalje, konoplja je pokazala sposobnost uklanjanja najvećih količina cinka (do 27,1 kg ha-1) dok je kod ostalih elemenata zabilježen niži stupanj uklanjanja (<0.80 kg ha-1). Najveći koeficijent biološke apsorpcije u alkalnom tlu imala je sorta Fibrol za molibden (BAC = 2,65) dok je u kiselom tlu imala Fedora 17 za kadmij (BAC = 16,1).
Budući da teški metali u sjemenu ograničavaju upotrebu konoplje u prehrambene svrhe, oni ne utječu na kvalitetu vlakna. Takva se kontaminirana vlakna mogu koristiti u proizvodnji kombiniranih materijala ili proizvodnji energije u kogeneracijskim postrojenjima. Less

Abstract (english)

Hemp (Cannabis sativa L.) is annual plant from Cannabaceae family. Cannabis genus consists of one species Cannabis sativa, and three subspecies; Cannabis sativa L. ssp. sativa, Cannabis sativa L. ssp. indica, Cannabis sativa L. ssp. Ruderalis. Originally from Central Asia. Industrial hemp (Cannabis sativa L.) has been manufactured for it's fiber and seeds for centuries.
The objectives of this research were to determine the possibility of accumulation of heavy metals from the ground... More using four strains of hemp (Fedora 17, Fibrol, Futura 75 and Santhica 27) at different soil reaction values, and to verify the hypothesis of hemp being hyperaccumulator of heavy metals.
The pH values of soil were the main factor affecting he adoption of the tested metals (Cd, Cu, Ni, Pb, Zn, Cr, Hg, Co, Mo and As) measured in the roots of hemp, stems and leaves. Based on this research it is concluded that the Fibrol variety can be used to remove heavy metals. Furthermore, hemp showed the ability to remove the largest amounts of zinc (up to 27.1 kg ha-1) while other elements had a lower degree of removal (<0.80 kg ha-1). Moreover, the highest degree of absorption in the alkaline soil had the Fibrol variety (Mo - BAC = 2.65) while in the acidic soil it had Fedora 17 (Cd - BAC = 16.1).
Since heavy metals in the seed limits the use of hemp for nutritional purposes, they do not affect fiber quality. Such contaminated fibers can be used in the production of combined materials or energy production in cogeneration plants. Less
