Percentage of <i>Tillandsia</i> capsules with immobilized seeds and number of immobilized seeds attached to the capsules/inflorescence.

Capsules were experimentally bagged in order to avoid the rain but treated with sprayed water (Sprayed treatment), bagged to avoid the rain and not sprayed with water (Bagged treatment) or left naturally exposed to the rain (Open treatment). Different letters denote significant differences between the Sprayed and Open treatments. Sample size (n) refers to the number of capsules used in each treatment. Test statistics are also shown, Mann-Whitney U, for the number of immobilized seeds and z for the percentage of capsules. * = P < 0.05, ** = P < 0.0001, ns = non-significant differences.
