A case study of learning in plants: Lessons learned from pea plants.

To facilitate the study of learning in plants, we share our experiences of trying to replicate the pea plant experiment of Gagliano et al. In the course of our efforts, we identified 11 issues that must be addressed when attempting to replicate these experiments. The issues range from germination and transplantation of seedlings to experimental design and apparatus issues. We propose a number of solutions to overcome these hurdles.
