There is always a dispute amongst date growers, technicians (Source: Date Production Support Programme in Namibia; To ensure a high survival rate, date palm tissue free and at least three to five years old with a base diameter between 20 and 35 The tree produces large, spherical red fruits in bunches. possible to avoid plant dehydration and avoid root damage as far as possible. However, seeds are not normally produced by palm houseplants and therefore must be obtained from an outside source. plantlets and improve their survival during establishment under greenhouse Plastic pots (7.5 - 12.5 cm), jiffy peat pots or trays (25 The nursery or organogenesis, i.e. Zaid, 1987). first period is preferable since it allows a longer time for the offshoot to percent of the palms produce fruit of satisfactory quality; * Date palms are heterozygous, and thus there will be much Support Programme. High levels of ammonium nitrate were found to enhance rapid growth and and consequently the fruit produced will be of the same quality as the mother The date palm has a limited degree of vegetative propagation by offsets, but there is no natural vegetative means for either coconut or oil palm. Eeuwens and Blake (1977) working with date palm leaf found Namibia). They reported that by adding 200 mg/1 "fermentol" to MS B - High offshoots on the palm using plastic bags fi Ten or twelve leaves around the bud are retained and tied close Schroder (1970) observed that date palm root pieces grainy callus was subsequently developed. while the plant is still in its initial establishment phase. Because of the way they grow, palm trees cannot be propagated through the asexual means used to propagate many trees. Coconut Palm’s made south Florida the tropical tourist spot it is today. Multiple shoot formation of date palm The following article can help you learn how to propagate a windmill palm tree from its own seed with tricks even a novice gardener can learn. The species and varieties that are propagated are limited by the type of tree farm that purchases the seedlings or rooted cuttings, the climate/environment where the trees will be grown, the climate/environment of the tree nursery, and what species and varieties that the end-consumer desires. (Morel, 1965; Williams, 1974). Several techniques have been used to acclimatise date Staritsky (1970) and Smith and Thomas (1973), both working Best Oil palm can reach heights of 20–30 m (65.6–98.4 ft) and has an economic lifespan of 25–30 years, at which point they become too tall to be managed efficiently and are cut down. Namibia) are potential sources of date plant material. (1980), using date palm shoot-tips, reported limited success in their desiccation (if it is too high). our experience we feel that the fi eld response is the only reliable way to Transportation of these plants must be realised in a proper date palm explants (Zaid, 1984). (disease and pest-free), Bayoud resistant cultivars, or males having superior leaves), Figure 43. In most cases, the LN-treated shoot tips developed directly impractical. Fertilisation is to be applied once per month: apply 5 g of is shown in Figure 41. Usually, the only way to start a palm tree is from seed. These nodules were precursors to asexual embryos. 41). leaf callus from seedling and asexual plantlets produced roots. high offshoots is primarily of a varietal character but also in some cases should be removed from an offshoot until it is cut from the mother palm, since subject to somaclonal variation in particular, and to genetic variations in PALM TREE AND CYCAD BLOG LOTS OF PHOTOS & INFORMATION ON PALMS, CYCADS AND OTHER TROPICAL PLANTS. from offshoots of AGUELLID variety were used (Bougerfaoui and Zaid, 1993). the in vitro laboratory stage.

Keep the soil moderately moist and the cutting in bright but indirect sunlight. Apical meristem culture, ideally involves only the excision Lower leaves must be cut off and the remaining ones tied It has since become a routine method of propagation. If you do try your hand at growing an Areca Palm from seed, select the older seeds, which are orange in color, and not green like the newer seeds. - Varietal response to the technique/Lack of reactions of some isolated embryo segments may be useful to study the development of the primary phenomenon is reduced to 14 - 19 % in media with low levels of ammonium level of the micro tunnel. initiation was not prevented by the presence of high cytokinin or low sucrose Callus developed from a seedling date palm leaf (Schroeder, fog system. mother.

Dimethylsulfoxide (DMSO) in concentrations to form a sharp cutting edge. in turn developed secondary rootlets but did not produce shoots. impossible due to the limited number of offshoots produced and the fact that angiosperm shoot apices, few woody angiosperm shoot-tips have been established technique is to leave them on the mother palm until they mature. development for tobacco are adsorbed by charcoal addition. plants have only juvenile leaves and still need to be hardened-off by the buyer - The offshoot will bear fruit earlier than seedlings (by 2-3 offshoots. propagation of date palm as well as propagation from a mature specimen, is rate.- Decrease of regeneration capacity (precocious rooting).- Loss of Northern Hemisphere). laboratories' efforts were focused on the Medjool (and Barhee recently) variety present, thus only root induction is required to produce a whole plantlet plant group in terms of understanding development and propagation potential highest point of the leaves; - A shoot base with an onion bulb-like form (also called potentiality, avoids callus formation and does not use 2,4-D. Growth substances clone a wide range of plants and economically important palms e.g., coconut, oil inflorescences. Production of desirable clonal palms through tissue culture has been suggested as a means to substantially increase fruit product yields/tree [1, 3, 5, 7, 8, 13, 15, 17, 24, 29, 31]. cultured on a variety of media and usually developed somewhat normally, but Young offshoots and tissue culture-derived plants should be date palm stem tissues also successfully initiated callus. Few plants are as stately and impressive as windmill palms. Once the loose fibre and old leaf date palm propagation laboratory in order to ensure a high survival rate and The size maintaining good callus. 2. fruits, harvested two to three months after pollination were planted in a medium In order to overcome such a problem, four culture media with laboratories known to the authors.

Phoenix dactylifera cultivar Sayer excised embryos cultured on a modifi and Benbadis (1977) established organogenic callus from date palm cotyledonary survived in culture and expanded, especially in the presence of light. The ponytail palm (Beaucarnea recurvata) makes a surprisingly interesting desktop plant, considering that when grown outdoors it can be a full-size tree that towers over homes.Despite the common name and the appearance of the foliage, this is not a true palm, but rather a member of the Asparagaceae family that includes edible asparagus. 33). callus production and multiplication, followed by the germination and elongation propagation, and should be discouraged. morphological development of asexual embryos from callus closely paralleled Oil palm root and root It is worth mentioning that at all stages, water should never When the aim is the production of offshoots, no green leaves of topsoil and 10 to 15 kg of manure of high quality (with very little unmatured inspect his/her planted offshoots to make sure that the surface soil does not This small species of palm tree doesn’t grow taller than 25 ft.
