Results of experiments to determine the breeding systems of the two forms of Eulophia parviflora
| Form | Mesurement of fecundity | Treatment |
Test statistic | |||
|---|---|---|---|---|---|---|
| Bagged and unmanipulated | Self-pollinated | Cross-pollinated | Intermorph cross | |||
| Short-spurred | Percentage fruit set (n) | 0 (n = 18) | 66 (n = 29) | 70 (n = 26) | 85 (n = 7) | |
| Mean (± s.e.) capsule and seed mass in g* (n) | – | 0·48 ± 0·08 (n = 19) | 0·56 ± 0·09 (n = 18) | 0·33 ± 0·05 (n = 6) | H = 1·731, P = 0·421 | |
| Mean (± s.e.) percentage of seeds with embryos* (n) | – | 44·7 ± 6·5a (n = 19) | 83·8 ± 4·1b (n = 18) | 86·3 ± 2·5b (n = 6) | H = 19·88, P < 0·0001 | |
| Long-spurred | Percentage fruit set (n) | 0 (n = 32) | Not recorded | Not recorded | Not recorded | |
| Mean (± se) capsule and seed mass in grams* (n) | – | 0·22 ± 0·02 (n = 9) | 0·23 ± 0·03 (n = 8) | 0·29 ± 0·05 (n = 7) | H = 1·70, P = 0·428 | |
| Mean (± se) percentage of seeds with embryos* (n) | – | 20·2 ± 5·3a (n = 9) | 86·6 ± 1·6b (n = 8) | 84·5 ± 1·6b (n = 7) | H = 16·31, P = 0·0003 | |
*Mass and seed set data were compared using Kruskall–Wallis test.
Homogenous groups were identified using Mann–Whitney post-hoc pairwise test and indicated with letters.
