For all we know, it could have been an apple tree, I actually doubt the fruit its self had any special properties to it. What gave them the knowelage of good and evil was the act of sinning, not obeying God. This act in its self instantly made them realize what they did and then knew what evil was, falling from their perfect state to sin.

To make an example, it would be the same as God saying "Do not eat a blade of grass or you will surly die". It could have been anything he said not to do, it wasn't the fruit or blade of grass its self.
