Let's talk about the "apriori pruning principle," if you like. Could you give me an example of this?

Alex thought that flower formation must be dependent on water. If this was true, he expected that the more water plants got, the more flowers they would produce. In order to test this, he obtained 200 identical petunia plants. He separated these into twenty groups of 10 plants each. He re-potted each petunia into identical containers, using the same bag of potting soil. He placed each group of plants in a large open field with no shade. Group 1 received only rain water. Each of the other groups received 10 additional ml of water, plants in group 3 received 20 additional ml of water and so on, so that plants in group 20 each received a total of 190 ml of water each evening, in addition to the rainwater. The plants were allowed to grow under these conditions for three months. When the plants bloomed, Alex recorded the number of blossoms on each petunia.
