Other claims from this paper (18)
- Observation No seed set occurred in the cross of L. concolor with Asiatic Hybrids by normal or cut-style pollination.
- Observation Hybrids were obtained in the reciprocal cross by cut-style pollination and embryo culture.
- Observation The ovary set rate was 100% in the reciprocal cross.
- Observation Average number of embryos per ovary was 5.1, ranging from 0.5 to 21.
- Observation Hybrid seeds did not germinate in vermiculite.
- Observation Survival rate in embryo culture averaged 47.4%.
- Observation Average pollen fertility rate among 11 hybrids was 72.9%.
- Observation Hybrids backcrossed to Asiatic Hybrids yielded few seeds.
- Observation Asiatic Hybrids produced many seeds when pollinated with hybrid pollen.
- Observation L. concolor produced no seed when pollinated with hybrid pollen.
- Observation About half of the seeds obtained from backcrosses were abnormal.
- Observation Only 20.3 to 34.0% of backcross seeds germinated in vermiculite.
- Intervention effect Excised immature embryos increased survival rate above 73.6% in backcrosses.
- Observation Flowers and leaves of hybrids were intermediate between their parents.
- Observation Hybrids grew vigorously, with longer stems and more flowers per inflorescence than their parents.
- Observation Hybrids were similar to L. concolor rather than to the Asiatic Hybrids, with relatively small flowers and slender leaves.
- Observation Hybrids forced in winter flowered in about 90 days.
- Observation Hybrids cultured after bulb harvest and storage flowered in about 65 days.
