Testing marshmallow seed germination on different substrates (Althaea officinalis L.)

Abstract

In this paper the results of the research of marsh-mallow seed germination on three substrates: filter paper, sand and soil are presented. The part of seeds was germinated on the substrate soaked by potassium nitrate (treatment) and the other one was germinated on the non-treated substrate (control). The first count was determined after seven days and total germination was determined twenty days after seed was germinated. The obtained results show that filter paper is more suitable substrate for marsh-mallow research than sand or soil, which is confirmed by the results of the first count and total germination. Potassium nitrate stimulated marsh-mallow seed and increased germination in comparison with the control of all investigated substrates. The highest germination was in the seed treated by potassium nitrate on filter paper substrate. .

U radu su prikazani rezultati ispitivanja klijavosti semena belog sleza na tri podloge: filter papiru, pesku i zemljištu. Deo semena naklijavan je na podlozi natopljenoj kalijum nitratom (tretman), a drugi na netretiranoj podlozi (kontrola). Energija klijanja utvrđena je posle sedam dana a ukupna klijavost nakon 20 dana od stavljanja semena na klijanje. Dobijeni rezultati pokazuju da je filter papir pogodnija podloga za ispitivanje belog sleza od peska ili zemljišta što potvrđuju rezultati energije klijanja i ukupne klijavosti. Kalijum nitrat delovao je stimulativno na seme belog sleza i povećao klijavost u odnosu na kontrolu na svim ispitivanim podlogama. Najvišu klijavost imalo je seme tretirano kalijum nitratom ispitivano na podlozi od filter papira. .
