The Effects of Different Treatments on Birch Spouting during Phases 2 and 3.

<p>The number of stump sprouts of birch (<i>Betula pendula</i> and <i>B</i>. <i>pubescens</i>) per investigated stump one growing season after the treatments a) in Phase 2 (Porvoo in 2009) and b) Phase 3 (Turenki in 2010). C = control, i.e., cutting only; LC = liquid control, i.e., cut stumps were spread with the inoculum medium without <i>C</i>. <i>purpureum</i>; HY4, P4 and 3.11 = the best parental strains of <i>C</i>. <i>purpureum</i>; E+₁, R1₂-R11₂, R13₂-R14₂, V1₂-V2₂, and R1₃-R12₃ = progenies of <i>C</i>. <i>purpureum</i> strains, see <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0117381#pone.0117381.t002" target="_blank">Table 2</a>.
