| 中文摘要: |
| 从广东银杏产区南雄市引种300株“雄银白果”银杏嫁接苗盆栽于广州市番禺区钟村农场，经过长达10年以上的驯化栽培，获得3株能正常开雌花的植株和2株能正常开雄花的植株。其开花期和盛花期相对于原产地迟3 ~ 6 d，萌芽期和展叶期也迟于原产地2 ~ 4 d；经人工授粉后已全部结实，但种子成熟期和落叶期比原产地推迟6~ 9d。收获的银杏种子比原产地同品种者略小，但种仁的食用品质与原产地同品种者接近，并能正常萌发和生长出幼苗。 |
| 英文摘要: |
| 250 female and 50 male grafted seedlings of Ginkgo biloba L. cv. ‘Xionying Baiguo’ from Nanxion city, Guangdong Province, were pot-cultivated in Guangzhou city, Guangdong Province. After 10 years of cultivation and domestication, 3 female plants and 2 male plants of these plants have been flowering for 3 years. Flowering phase of the flowered plants were 3 ~ 6 d later than those in Nanxion City, while their budding and peak leafing phase were 2 ~ 4 d later than those in Nanxion City. The flowered female plants were artificially pollinated and many seeds were harvested. Their seed maturity and leaf falling phase were 6 ~ 9 d later than those in Nanxion City. The seeds could normally germinated and sprout although they were smaller than those in Nanxion City. The edible quality of kernel was not significantly different from that in Nanxion City. |
