摘要: The ornamental species Hemerocallis hybrida Hort. is a perennial herbaceous plant originated in Asia. objective of the present work to study artificial methods hybridization¸ floral biology and reproductive system daylily plants support genetic breeding programs this species. technique covering stigma daylily's flowers with aluminum paper instead whole flower after crossing, provides higher setting maturation seed capsules (p < 0,001; Test 2 contingency x 2; correction Yates). Blooming best phenophase for controlled crossings estigmatic reception 100%, amount viable pollen grains 45% then phase senescence. studied hermaphrodite, essentially allogamous, self-incompatibility autogamy indexes equal zero.
