木槿属4种植物花粉活力和杂交亲和性研究
Studies on pollen viability and cross-compatibility of four species of Hibiscus
摘要
Abstract
Pollen viability, storage method, crossing incompatibilities and young embryo culture were investigated for four Hibiscus species, e.g. H. mutabilis f. mutabilis, H. syriacus var. syriacus, H. rosa⁃sinensis var. rosa⁃sinensis, and H. roses⁃sinensis var. rubro⁃plenus, so as to provide the basis in the cultivation of new varieties of Hibiscus. The results were shown as follows:① The pollen germination rate of all four species was relatively high. It could be arranged as:H. mu⁃tabilis f. mutabilis 88.3%, H. roses⁃sinensis var. rubro⁃plenus 82.5%, H. rosa⁃sinensis var. rosa⁃sinensis 77.8%, H. syria⁃cus var. syriacus 76.1%;② The pollen was not appropriate to storage at room temperature and 4 ℃, and the longest storage time was 2 d;③The cross incompatibilities between Hibiscus species was low and the seed setting rate was 12%for H. mutabilis f. mutabilis ×H. roses⁃sinensis var. rubro⁃plenus, 8% for H. mutabilis f. mutabilis ×H. rosa⁃sinensis var. rosa⁃sinensis, and 3% for H. mutabilis f. mutabilis ×H. syriacus var. syriacus;④ the appropriate medium of young em⁃bryo of H. mutabilis f. mutabilis ×H. rosa⁃sinensis var. rosa⁃sinensis in vitro culture was WPM+IBA 1.0 mg/L+BA 0.1 mg/L, the germination rate was 56.6%.关键词
