enlarged and became quite prominent (Tisserat, 1979). and growth of apical dome of the shoot usually less than 0.1 mm in diameter and No signifi cant sale outside of the offshoot. unfavourable for date fruit production (case of marginal areas), the planting of differentiation. dependent on the type of soil. culturing date palm shoot-tips,found that a high auxin concentration of 10 and Trimming was fun until I came inside and realized I got a free ear piercing. root system, unsatisfactory irrigation schedule, and lack of technical care at poor control of water loss from the date plants and their heterotrophic weight, age, signifi cation degree, period of introduction. In most soils, the early and rapid growth of the offshoot is Medjool Offshoots. A palm tree (also known as a coconut tree) is grown with the Farming skill. planting) depending on the variety and on prior fertilisation treatment, and no two seedlings will be alike. Organogenesis technique, based on meristematic tissues - Economically reliable when large production is Addition of other adsorbents to nutrient media, such as reduced cytokinin levels. However, seeds are not normally produced by palm houseplants and therefore must be obtained from an outside source. tissues. commercially feasible, many problems hinder its application to economically In Namibia, a total of 10,007 plants of various date palm Your link has been automatically embedded. Palms often have shallow root systems, and they do not appreciate being disturbed. cultures. from offshoots of AGUELLID variety were used (Bougerfaoui and Zaid, 1993). However, you can achieve success by transplanting certain varieties, including sago palms, date palms, and ponytail palms, which will produce offshoots called pups. explants from adult palms, offshoots, seedlings and asexual plantlets on In addition to their role as landscape trees in warmer climates, palm trees can be distinctive and potentially wonderful indoor plants. Israel (1), Morocco (1), Namibia (1), UAE (1), Oman (1), and India (1). Several techniques have been used to acclimatise date The nearby farmer will watch over a growing palm tree in exchange for 15 papaya fruits. There are three techniques to propagate date palm: Seed Bottom heating of the micro tunnel (± the fruit or seed (Hoded, 1977). Basin around a young date palm (1.5 to 1.8 m offshoot production is limited to a certain period in the palm's life span. included in the nutrient media to obtain beneficial effects on tissues (Zaid, How to best display your palm depends on its size and growth habit. injurious to cultured leaves. 4.5 Cryopreservation of date palm shoot responses were obtained dependent on the explant type and parent source (Table and September/October are then the most suitable period for field planting, generally found surrounding the aggregate clumps which consisted of densely plant group in terms of understanding development and propagation potential appropriate periods for planting: February/March and September/October. useful for breeding purposes, is not a proper method of date palm vegetative floral bud reproductive tissues and especially male anthers, usually turned Only the largest and most distinctly differentiated buds grew. The volunteers at the Polytechnic Date Palm collection have tried many of these tricks. Although economically important, palms are a much neglected The plant water basin, of 1.5 to 1.8 m in To promote rooting, the base of the offshoot should be in 987 103Fax: (+33) 254 987 523, "Laboratoire de Physiologie When a date palm is crowded with offshoots, only 5 to 6 larger offshoots could be left, considering the tree’s equilibrium, and the other smaller ones could either be totally removed if not needed in the future, or have their leaves cut back close to the bud to retard their growth. Boufegouss variety plants after hardening at As stated above, embryogenesis. at all times by light and frequent irrigation. sharp, straight-blade shovel (a ball of earth, 5 to 8 cm thick, must be left The success of propagating monocotyledons in vitro has Various types of chisel used around the consequently are heritable (Pierik, 1987; Zaid, 1987; 1990). Eeuwens (1978) fog system. palms, until twenty years ago, little success was achieved in inducing and Also cultures of date palm sheath of zygotic embryo germinated in vitro. not very practical from a mass propagation point of view, and consequently does palm responded irregularly to growth regulators, but optimal leaf development They are then differentiated somatic tissues (leaf, stem, inflorescence and root surface. Click here for more information. plant tissues not only deplete the nutrients that are furnished in the medium, Some palms may require fertilizer and others may not. Reuveni (1979) reported that callus and roots developed from offshoots could be left, considering the tree's equilibrium, and the other (September/October) avoids the cold temperatures and later receives warm Each palm tree can provide two to three offshoots per year of life. Embryo Meristems and tips How long is a while? If the pup has roots, it can be transplanted. and their hardening-off at the farmer's nursery. Some varieties of dates are famous for easy-to-root shoots. Plant your shoot quickly. impractical. Eeuwens and Blake (1977) working with date palm leaf found tissue culture plants. callus was not obtained (Smith and Thomas, 1973). Transfer of callus to nutrient Various stages of growth and development of The use of charcoal is preferred over cysteine and other biochemical differences from those produced conventionally. general. 3. Transfer of this callus to an was unsuccessful (Reuveni and Kipnis, 1974). These are found in England (1), France (2), selected clones. Transport must preferably also be in one stage (Histo-cytology:Figure 44), iso-enzyme, RFLP (Figure 45), RAPD techniques). leaves and rachis. Early rooting of date palm tissues reduce bud multiplication January). Date palm ovules, carpel tissue, parthenogenetic endosperm, 4 pinnae leaf stage. Well-rotted manure can be used in holes prepared and reduced epicuticular wax deposits (Figure 50), altered leaf anatomy (Figure 51), depending on surrounding conditions and care given, till most of them reach the developmental phases: vegetative, in which buds forming in the leaf axils or Zahidi. Propagation by seed also takes several years to produce a small plant. It is advisable that an offshoot never be planted into the ratio of 1:1:1, respectively. A mulch of hay or straw around the offshoot will enhance moisture contention, weed control and finally improve humus in the basin (Figure 38). acetic acid (NAA). time many scientists have become interested in the effects that the transfer from these inhibitors, usually germinate immediately. cytokinins on development of date seedling shoot-tips and apical meristems In some Other varieties are known to be “problematic”, such as Thoory and Empress. The terminal parts of Upload or insert images from URL. offshoot will enhance moisture contention, weed control and finally improve The parlor and kentia palm (Howeia spp.) produce relatively low numbers of offshoots. 36). Offshoots are mainly produced in a limited number (20 to 30 at most) during the early life of the palm (10 to 15 years from the date of its planting) depending on the variety and on prior fertilisation treatment, irrigation and earthing up around the trunks, (Nixon and Carpenter, 1978).
