The best charcoal concentration for SBIs from AG-1 IC was 0.5%, from AG-2-3 was 1%, and from AG-2-2 IV was 2%. The optimal concentration was 0% for SPIs from AG-1 IA. The optimal charcoal concentrations used for tuff formation between SBIs and between SPIs are quite varied, depending on the different AGs. The results of AFLP haplotypes suggest that tuff isolates formed between SBIs/SPIs are heterokaryon.展开更多
