Then cut its stem beneath the roots and plant it in a pot of fine orchid bark, keeping its roots near the surface. Set the cuttings aside. They will grow outdoors in U. The new leaves will grow up, and the roots will wind their way through the potting medium.
Still nurtured by the mother plant, the keiki will grow roots into the growing medium.
Moth orchids are epiphytic, meaning they grow on branches and trees but are not parasitic -- their roots take in nourishment from air and water, not their host. The Noble Dendrobium Dendrobium nobilehardy in U. Plant the new plantlet with the old stem standing upright and the shoots facing to the side or upward.
Growing Keikies Keiki is the Hawaiian word for baby.
Mist daily until the roots are firmly established in the potting mix, then water weekly or when the potting mix dries slightly. Layering Keikies A third technique for growing a Phalaenopsis keiki offset is a variation of layering, the practice of bending a plant to the ground to grow roots.
Though orchid micropropagation has shown spectacular development in the recent years, the wide spread use of micropropagation is believed to be still limited due to problems like exudation of phenolics from explants, transplantation to field, somaclonal variation etc.
After that, water only when soil is dry, and keep root tips out of standing water. Encase the tray in a transparent plastic bag and place it in a warm position where it will receive bright light but no direct sun.
Here are the directions: Phalaenopsis orchids, white or in shades of pink or yellow, are easy to propagate and grow. If a new plant is not desired, the keiki can be removed at any time.
JA jasomonic acid Development is regulated by phytohormone-induced responses which ultimately govern form and function throughout the life of the plant.
After laying the pieces horizontally on top of the medium in the tray, press them only lightly into it so that their surfaces remain uncovered.
Water your new orchids until water leaks from the bottom drainage holes once per week and fertilize every three weeks with a liquid orchid fertilizer from spring to mid-fall.
Cover the tray loosely with plastic wrap to keep the humidity high. Continue to use the foliar fertilizer every two weeks until the cuttings develop leaves and roots.
Potting Basics After the cuttings develop new shoots and roots, gently cut the stem between the plantlets using sterilized anvil pruners. Divide the stem into several 3- to 4-inch sections, making sure each segment has a dormant bud. Moth orchids like bright, indirect light.
Temperature Control Keep your phalaenopsis orchids very warm: When a keiki develops several good roots about 3 inches long, sever it from the stem and plant it in its own pot.
After a month, begin to fertilize weekly for three weeks out of four, with a 25 percent solution of the recommended flower fertilizer concentration. Divide Your Existing Orchid Plant At the end of the previous growing season, the orchid will have many aerial root sprouts and lean heavily in its pot.
Department of Agriculture plant hardiness zones 10 through 12, but are commonly grown indoors.Micropropagation of orchids: A review on the potential of different explants. Author links open overlay panel Samira Chugh Satyakam Guha I.
Usha Rao. Show more.
(conjugates of indole acetic acid and amino acids) have also been utilized in the in vitro propagation of Phalaenopsis orchids. Dendrobium orchids may be propagated using stem cuttings. When kept warm and moist in a dark location, roots and leaves will develop from the orchid's stem nodes.
Propagation of Noble. Auxin's capacity to regulate aspects of plant development has been well characterized in model plant systems. In contrast, orchids have received considerably less attention, but the realization that many orchid species are endangered has led to culture-based propagation studies which have unveiled some functions for auxin in this system.
How To Clone Orchids Using Keiki Paste. UK STOCK HERE - Keiki paste is a cytokinin hormone which induces growth in the node of a Phalaenopsis inflorescence. It should not be confused with paste or powder containing auxins, which are used to force the production of roots.
Considering the fact that Phalaenopsis orchids can tolerate rather low light, There is also an artificial technique to make keikis on Phalaenopsis – with special cytokinin paste you can obtain many new plants.
Due to an artificial propagation of orchids at home by seeds is a pretty difficult task, and the impossibility to reproduce. Micropropagation of Phalaenopsis Orchids via Protocorms and Protocorm-Like Bodies In vitro propagation makes it possible to clonally mass propagate hybrids of commercial value and conserved.Download
