The study has several implications that should be taken into consideration in botany lessons. First, visual, colourful presentations of plants should include exposure of their fruits or seeds that promote information retention. In particular, contrasting colours of fruits may increase student’s attention, interest and consequently information retention about these plants. Second, talking about plants should contain survival-relevant information. This information includes plant edibility, the presence of toxic substances, medical importance of plants and incidences that can cause human death. For example, the hemlock (Conium maculatum) lacks any attractive seeds or other features potentially attractive to children, but the story of Socrates who was given a potent infusion of the hemlock and died can positively influence retention of information about this species. Finally, there was some evidence that the children involved in the research associated red colour with a fruit being edible, and black or green colours with toxic fruits, although this was not conclusive. Teachers should teach children that plants, similar to animals, possess aposematic, warning colours, and unknown fruits (with contrasting colour) should not be consumed.
