Starch granule morphology
Scanning electron micrographs were taken by a JSM-5300LV
scanning electron microscope (JEOL, Tokyo, Japan) at the Department
of Biology, Khon Kaen University, Thailand. Starch samples
were fixed onto circular specimen stubs using double-sided sticky
tape, and vacuum-coated with gold/palladium (60/40). An accelerating
potential of 10 kV was used during micrography.
