2.2. Effects of exogenous factors on the growth of G. changii
Four different exogenous factors: the strength of PES, commercial
fertilizers/biostimulant, plant growth regulators, and salinity
were studied to understand their effects on the growth of G. changii
in vitro. Seaweed segments in approximately 5 mm (0.02 g) were
used as explant materials for each experiment. Total of 5 explants
were cultured in Fernbach culture vessel with 100 mL of medium
for each experimental condition. The experiments were carried out
in triplicate
