| dc.description.abstract | The study of “Catechin Production of In Vitro Culture of Tea Callus
(Camellia sinensis L.) was elicitated by Saccharomyces cerevisiae” has been done
from March 2014 to October 2014 at Plant Tissue Culture Laboratory of
Mathematics and Science Faculty of Sumatera Utara University, and Trial Quality
and Pesticides Residues Laboratory of The Technical Excutive Unit a Protect
Crops and Horticulture in Medan. The aim of this research was to know the
concentration of Saccharomyces cerevisiae’s cell walls elicitors to increase
cathechin production. The experimental design was completely randomized non
factorial using Murashige and Skoog medium with 1 mg/L of 2,4-D and 1 mg/L of
kinetin that was added with Saccharomyces cerevisiae’s cell walls elicitors (with
numbers of elicitor’s concentration level). The statistical analysis showed that in
Murashige and Skoog medium with 1 mg/L of 2,4-D and 1 mg/L of kinetin as
control medium gave the best effect to increase fresh weights of tea callus
(Camellia sinensis L.), the increase of Saccharomyces cerevisiae’s cell walls
elicitors tend to cause an increase in the dry weights of tea callus. 0,50% is the
best elicitor’s concentration that is able to increase highest catechin production of
2,105 mg/g DW or increases 4 times compared to control. | en_US |
