The highest germination and germination energy (Germ. En.) for T. indica occurred following pre-treatment in methanol for 10 minutes (70% germination; 42, Germ. En.), while better response was obtained for P. africana following pretreatment in ethanol for 10 minutes (58% germination; 38, Germ. En.), and Conc. H2SO4, for 5 minutes (60% germination; 38, Germ. En.).application/pdfQH301 Biology, SB Plant cultureArticle
