Selenicereus undatus, the white-fleshed pitahaya, is a species of the genus Selenicereus (formerly Hylocereus) in the family Cactaceae [1] and is the most cultivated species in the genus. It is used both as an ornamental vine and as a fruit crop – the pitahaya or dragon fruit. [3]
The simplest method of propagating a tree vegetatively is rooting or taking cuttings. A cutting (usually a piece of stem of the parent plant) is cut off and stuck into soil. Artificial rooting hormones are sometimes used to improve chances of success.
Shield budding, also known as T-budding, is a technique of grafting to change varieties of fruit trees. Typically used in fruit tree propagation, it can also be used for many other kinds of nursery stock. [1] An extremely sharp knife is necessary; specialty budding knives are on the market.
Fresh ripe dragon fruit in Vietnam. Sweet pitayas come in three types, all with leathery, slightly leafy skin: [3]: 215–216 Selenicereus undatus (Pitaya blanca or white-fleshed pitaya, also known as Hylocereus undatus) has pink-skinned fruit with white flesh. This is the most commonly seen "dragon fruit".
Flowers ca. 22 cm long, 21 cm wide, base with small, narrow, widely spaced scales, sometimes spiny. Fruit red. May be a synonym of Selenicereus triangularis: the Caribbean. [29] Selenicereus undatus (Haw.) D.R.Hunt: Stems green, margins undulate and horny. Flowers 25–30 cm long, white with green outer tepals and bracts. Fruit red with white pulp.
Therefore, propagation via asexual seeds or apomixis is asexual reproduction but not vegetative propagation. [6] Softwood stem cuttings rooting in a controlled environment. Techniques for vegetative propagation include: Air or ground layering; Division; Grafting and bud grafting, widely used in fruit tree propagation; Micropropagation; Offsets ...
Propagation: Both commercially and in the home, propagation can be achieved by using short pieces of stem, one to three segments long, twisted off rather than cut. Cuttings are allowed to dry for 1–7 days, forming a callus at the broken end, and then rooted in an open growing medium. Temperatures above 21 °C (70 °F) and up to 27 °C (81 °F ...
Dracaena draco, the Canary Islands dragon tree or drago, [4] is a subtropical tree in the genus Dracaena, native to the Canary Islands, Cape Verde, Madeira, western Morocco, and possibly introduced into the Azores. [5] It was first described by Carl Linnaeus in 1762 as Asparagus draco. [3] [6] In 1767 he assigned it to the new genus, Dracaena ...
