“…Ginkgo shows tolerance to a suite of gaseous air pollutants, except for a sensitivity to simulated acid rain (Kim, 1987; Oh et al, 1983). It was tolerant to sulphur dioxide, nitrogen oxides and ozone while it was moderately sensitive to fluorides (Davis & Gerhold, 1976; Davis & Wilhour, 1976; Karnosky, 1978; Weinstein, 1977). An investigation on the degree of leaf damage resulting from air pollutants suggested that Ginkgo was more tolerant to air pollution than 15 other trees, namely Pinus koraiensis , Pinus rigida , Abies holophylla , Pinus densiflora , C. japonica , Chamaecyparis pisifera , Chamaecyparis obtusa , Juniperus chinensis , Quercus serrata , Betula platyphylla , Populus occidentalis , Populus euramericana , Prunus jedoensis , Populus alba × glandulos and Paulownia coreana (Oh et al, 1983).…”

This account presents information on all aspects of the biology of Ginkgo biloba L. (Ginkgo, Maidenhair tree) that are relevant to understanding its ecological characteristics. The main topics are presented within the standard framework of the International Biological Flora: distribution, habitat, communities, responses to biotic factors, responses to environment, structure and physiology, phenology, reproductive and seed characters, herbivores and disease, history, conservation and global heterogeneity. Globally, Ginkgo survives a wide range of mean annual temperature (−3.3 to 23.3°C) and annual precipitation (34–3925 mm) conditions, according to a meta‐analysis. It prefers a warm, humid, open‐canopy and a well‐drained environment. The species shows strong tolerance to drought, freezing, fire, air pollution, heavy metals and low‐level salt, whereas it is intolerant to long‐time shade and waterlogging. Six Ginkgo trees even survived the atom bomb in Hiroshima, Japan, during World War II. Ginkgo is susceptible to few diseases. Those occurring in nursery seedlings and juvenile trees involve stem rot and leaf blight. The former is caused by Macrophomina phaseoli, which could lead to a mortality rate of 5%–12% (up to 31.8%) for seedlings. This disease can be mitigated by a 4‐h shading treatment and applying organic fertilisers. The pathogens inducing leaf blight include Alternaria alternata, Colletotrichum gloeosporioides and Pestalotia ginkgo, which may infect 100% juvenile trees in some regions. The application of 45% carbendazim or 50% Tuzet can effectively prevent leaf blight. Ginkgo biloba is one of the world’s most distinctive trees with an important position in plant evolution and human society. It is a tall deciduous dioecious tree native to China. Refugial populations were identified in three glacial refugia located in eastern, southern and south‐western China, respectively, with a patchy distribution pattern and a small population size. It typically grows along flood‐disturbed streamsides in warm‐temperate deciduous (and evergreen mixed) broadleaved forests. Ginkgo may have been introduced repeatedly out of China since the sixth century. It has been planted as a landscape tree world‐wide, except in Antarctica. Ginkgo is also of great value for edible nuts, herbal medicine, religion and art. It is a natural and cultural symbol of China.
