Pyrus ussuriensis

Pyrus ussuriensis, also known as the Ussurian pear, Harbin pear, and Manchurian pear, is a species of flowering plant in the family Rosaceae. [1]

It is native to Korea, Japan, china, and the Ussuri River area of far eastern Russia. It has flowers in spring that are slightly pink when budding and then turn white. [2] Buds are dark brown and have an alternating arrangement. The tree grows to a height of about 15 meters (49 ft) and prefers well-drained loam-type soils. It is considered the hardiest of all pears. [3] When planted in milder climates, the trees have been known to be killed by freezes after they begin budding. [3] Many species of birds and mammals feed upon the fruit of this species. Deer, mice, and rabbits are known to damage the trees. [4] Leaves are dark green in spring and summer and turn dark red and gold in autumn. [2] Products made from the fruits may prove more effective than commercial insecticides in killing ticks and mites. [5] The fruits are not the tastiest of pears to humans, but the taste is better after a freeze and the juice tastes better. Crosses of this species with other pears produces tasty pears that grow in climates too cold for most pears. [3]

Cultivars include the 'Reli', 'Jinxiang', 'Hongbalixiang', 'Baibalixiang', 'Fuwuxiang', 'Qiuxiang', 'Fuanjianba', 'Longxiang', 'Guanhongxiao', 'Shanli24', 'Wuxiangli', 'Shatangli', 'Manyuanxiang', 'McDermand' , and the Prairie Gem® Flowering Pear (cultivar ‘MorDak’). [4] There are at least 108 compounds in the fruits that affect plant breeding and these show that P. ussuriensis cultivars fall into 4 groups. [6]

A mango is an edible stone fruit produced by the tropical tree Mangifera indica. It originated from the region between northwestern Myanmar, Bangladesh, and northeastern India. M. indica has been cultivated in South and Southeast Asia since ancient times resulting in two types of modern mango cultivars: the "Indian type" and the "Southeast Asian type".

A fruit tree is a tree which bears fruit that is consumed or used by animals and humans — all trees that are flowering plants produce fruit, which are the ripened ovaries of flowers containing one or more seeds. In horticultural usage, the term "fruit tree" is limited to those that provide fruit for human food. Types of fruits are described and defined elsewhere, but would include "fruit" in a culinary sense, as well as some nut-bearing trees, such as walnuts.

It is used as rootstock for cultivated pears, and the fruit are collected and eaten by local people.

Pyrus phaeocarpa, the dusky pear or orange pear, is a species of flowering plant in the family Rosaceae, native to the Loess Plateau of northern China. A wide tree reaching at most 7–8 m (23–26 ft) in height, it is hardy to USDA zone 5, or perhaps even zone 4. Its small yellow to brown fruit are edible, and its Autumn foliage is bright orange to orange-red, giving it good potential as an ornamental. Its chloroplast genome shows that it is closely related to Pyrus pashia, the wild Himalayan pear, and it is suspected to be a hybrid of P. betulifolia, the birchleaf pear, P. pyrifolia, the apple pear, and P. ussuriensis, the Manchurian pear.
