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, 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 is believed to have originated in southern Asia, particularly in eastern India, Bangladesh, and the Andaman Islands. 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". Other species in the genus Mangifera also produce edible fruits that are also called "mangoes", the majority of which are found in the Malesian ecoregion.

<span class="mw-page-title-main">Avocado</span> Species of flowering plant in the laurel family Lauraceae

The avocado is a medium-sized, evergreen tree in the laurel family (Lauraceae). It is native to the Americas and was first domesticated in Mesoamerica more than 5,000 years ago. Then as now it was prized for its large and unusually oily fruit. The tree likely originated in the highlands bridging south-central Mexico and Guatemala. Its fruit, sometimes also referred to as an alligator pear or avocado pear, is botanically a large berry containing a single large seed. Sequencing of its genome showed that the evolution of avocados was shaped by polyploidy events and that commercial varieties have an hybrid origin. Avocado trees are partly self-pollinating, and are often propagated through grafting to maintain consistent fruit output. Avocados are presently cultivated in the tropical and Mediterranean climates of many countries. Mexico is the world's leading producer of avocados as of 2020, supplying nearly 30% of the global harvest in that year.

<i>Pyrus pyrifolia</i> Species of pear with round crisp grainy fruit

Pyrus pyrifolia is a species of pear tree native to southern China and northern Indochina, and have been introduced to Korea, Japan and other parts of the world.

Along with cultivars of P. × bretschneideri and P. ussuriensis, the fruit is also called the nashi pear. Cultivars derived from Pyrus pyrifolia are grown throughout East Asia, and in other countries such as India, Pakistan, Nepal, Australia, New Zealand, and the United States. Traditionally in East Asia the tree's flowers are a popular symbol of early spring, and it is a common sight in gardens and the countryside.

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.
