Testing of moisture of marshmallow (Althaea officinalis L.) seeds

Abstract

The rules for testing seeds (ISTA, 2007) do not precisely determine temperature, the way of preparation of working seed sample and the length of drying seeds of marshmallow. The aim of this experiment was to determine the temperature and the length of drying for testing moisture of marshmallow (Althaea officinalis L.) seeds. The temperatures from 105°C to 130°C during 2 to 17 hours period of time were applied. Based on the results of seed testing it is concluded that the stabilisation of seed mass is achieved at 130°C. The values of the coefficient of variations are very low which implies that the applied methodology was reliable. .

Pravilima za ispitivanje semena (ISTA, 2007) nije preciznije ustanovljena temperatura, način pripreme radnog uzorka i dužina sušenja semena belog sleza. Cilj eksperimenta bio je određivanje temperature i dužine sušenja za ispitivanje vlažnosti semena belog sleza. Primenjivane su temperature od 105 do 130°C u trajanju od 2 do 17 sati. Na osnovu rezultata ispitivanja konstatovano je da se stabilizacija mase semena postiže na 130°C. Vrednosti koeficijenata varijacija su jako niske što ukazuje da je primenjena metodologija bila pouzdana. .
