The marionberry (Rubus L. subgenus Rubus) is a cultivar of blackberry released in 1956 by the USDA Agricultural Research Service breeding program in cooperation with Oregon State University. [ 1 ] [ 2 ] [ 3 ] It is named after Marion County, Oregon , where the berry was bred and tested extensively in the mid-20th century.
The term "cane fruit" or "cane berry" applies to any Rubus species or hybrid which is commonly grown with supports such as wires or canes, including raspberries, blackberries, and hybrids such as loganberry, boysenberry, marionberry and tayberry. [7] The stems of such plants are also referred to as canes.
Rubus ursinus is a wide, mounding shrub or vine, growing to 0.61–1.52 metres (2–5 feet) high, and more than 1.8 m (6 ft) wide. [3] The prickly branches can take root if they touch soil, thus enabling the plant to spread vegetatively and form larger clonal colonies.
A prickle-free mutation of the loganberry, the 'American Thornless', was developed in 1933. The tayberry is a similar raspberry-blackberry hybrid. The 'Phenomenal' berry or 'Burbank's Logan', developed by Luther Burbank in 1905, is also a raspberry-blackberry hybrid, but is a second-generation cross (i.e., two first-generation crosses between ...
Boysenberries grow on low, trailing plants. [3] It is a large aggregate fruit with a deep maroon color, weighing 8 grams (0.28 oz) and containing large seeds. [3] [4] The fruits are characterized by their soft texture, thin skins, and sweet-tart flavor. Mature fruits leak juice very easily and can start to decay within a few days of harvest. [3]

Gentian seedlings in a plant nursery. Plant propagation is the process by which new plants grow from various sources, including seeds, cuttings, and other plant parts. Plant propagation can refer to both man-made and natural processes. Propagation typically occurs as a step in the overall cycle of plant growth.
Micropropagation or tissue culture is the practice of rapidly multiplying plant stock material to produce many progeny plants, using modern plant tissue culture methods. [ 1 ] Micropropagation is used to multiply a wide variety of plants, such as those that have been genetically modified or bred through conventional plant breeding methods.
