Abstract
This experiments were conducted to evaluate the influence of Chlorella culture solution using anaerobic digestate as medium on seed germination of perennial ryegrass seeds. Four treatments were compared: control with distilled water, anaerobic digestate, Chlorella culture solution and Chlorella culture filtrate. The germination percentage of perennial ryegrass seeds was highest in the Chlorella culture solution treatment. Days required for 50, 70% seed germination were faster at 1.7 day in Chlorella culture solution compared to control. Root length of perennial ryegrass seeds was longer by 1~2cm in the Chlorella culture solution compared with control. The relative root length was by 40% longer in the Chlorella culture solution treatment compared to control. The germination index (GI) of perennial ryegrass seeds was higher by 180~202% in the Chlorella culture solution treatment compared to control. The decay rate was low as 50.0% in Chlorella culture solution, but decay rate of perennial ryegrass seeds showed 86.7~83.3% in control plot and in anaerobic digestate, respectively. Chlorella culture solution have shown stimulatory effects in germination and development of root. Overall, Chlorella culture solution could be useful to apply for promotion of germination and root elongation of seeds.
