Pseudomonas syringae cause of leaf spot and stem cankers.
Garden Partners –
Cultivars – ‘Albovariegata’ tree with a broad silhouette, slow growth.
‘Fairmont’ erected and narrowed silhouette, fast growth.
‘Horizontalis’ – very broad silhouette and big leaves, principal branches are in a horizontal position.
‘Tremonia’ – slender form, branches are in a horizontal position and are short.
Properties and Uses – Ginkgo is cultivated throughout the temperate zones of the world for ornamental purpose.
G. biloba roots are colonized by the fungus Glomus epigaeum, forming mycorrhiza.
In Traditional Chinese medicine the seeds are used as an astringent, to stop asthma and regulate urinary frequency.
The leaves of Ginkgo, are first mentioned in Pharmaceutical Natural History of Southern Yunnan, published in 1436 during the Ming dynasty, are used externally to treat skin and head sores.
Curiosity – until 350 years ago interest was restricted to China, its natural habitat, Japan and Korea. There female trees were cultivated on a large scale furnish the nuts which remain a popular delicacy in Eastern Asia until today. Most of the 100 species over 1000 years old that still exist in China are found near Buddhist or Daoist temples.
The Ginkgo was first imported to the United States in 1784 as an attractive ornamental plant.
The Ginkgoales appeared in the Permian era and were at maximum range in the Jurassic.
