-label - What are the 4 types of germination needs?
-
-ready to germinate, just give proper conditions
-scarification (needs to have the seed coat abraded)
-stratification (needs to have a period of cool-moist
-both scarification and stratification - How can scarification be replicated?
-
-using a file
-using sandpaper
-use rock tumbler filled with grit or lined with sandpaper
