Dear Paulo,
There's a difference between circular paths and circular nodes. If
you want to refer to the objects later, nodes are the way to go. Do
the same thing as you have with "split" and make a node style.
\documentclass[11pt]{minimal}
\usepackage{tikz}
\usetikzlibrary
{shapes,arrows,trees,matrix,positioning,decorations.pathmorphing,scopes}
\usepackage[T1]{fontenc}
\usepackage[active,tightpage]{preview}
\PreviewEnvironment{tikzpicture}
\setlength\PreviewBorder{1pt}%
\begin{document}
\begin{tikzpicture}[
split/.style={
rectangle,
minimum size=2mm,
solid,thick,draw=black!50,
top color=white,
bottom color=black},
disk/.style={
circle,
minimum size=2pt,
inner sep=0pt,
outer sep=0pt,
draw=black,fill=black}
]
\node(init){}
[every child node/.style={disk}]
child { node (a) {}}
child { node {}
child { node {}
child {node {}}
child {node {}}
}
child {node [split] (b){}}
}
child {node {}};
\draw[blue,dashed,->] (a)--(b);
\end{tikzpicture}
\end{document}
If you don't have the inner sep and outer sep options zeroed out, the
extra space added will make the circles a lot bigger than 2pt.
Hope that helps!
