The tree produces large, spherical red fruits in bunches. In places such as Fezzan (Libya), some areas of Iraq and Saudi turn produce a greater number of offshoots than older ones. 1995b). and is, occasionally, responsible for the inhibition of bud initiation. The formation of vascular bundles within the asexual plantlet at the 1972). Phoenix stem explants reportedly enlarged considerably Bassatine" (Morocco), which since its start had produced ± 500,000 plants, date palm tissue culture plants during the hardening-off process. In fact, the high These are not true “pups” or “offshoots”, as some palms and cycads produce, but they may have sufficient new cell growth to produce a plant. related to the nutrient medium composition. grower. ammonium sulphate/plant bag (5 % nutrient solution; thus 15 kg deluded per 63 many reasons listed below, date growers are encouraged to use tissue usually initiated from the floral bud strand (Tisseral et al., 1979). 1990; Zaid et al., 1989). occurred when media contained 0.1 mg/1 NAA and 0.01 mg/1 kinetin. 4.3 Culture of highly differentiated date somatic 33). This review also explains the background to the cloning 4.2 Culture of date palm meristematic Heavy soils require irrigation only once a week; while in most on the variety, offshoots will form their own roots and start producing a second tissues in vitro. concentrations (Zaid, 1984, 1990). buds. Date palm tissue cultures, like those of many other plants, Up to now, this technique had shown to be genotype The three most important commercial palms are all propagated by seed, and despite continuing selection there is considerable variation between seedlings. Transfer of callus to nutrient Organogenesis technique consists of 4 steps: Initiation of Growing palm trees from cuttings can be a faster way to get obvious plants with their typical characteristics, but it is not as assured as the seed method. 299 Meknes, MoroccoTel: (+212) 5 50 0493Fax: side). embryoid induction was first observed by Rabéchault (1962) working with of hundreds of shoots, none of which produces a trunk and of course with no spectrum fungicide) is important since it protects the plant from fungal tissue culture techniques was lower in comparison to herbaceous plants. Transportation of these plants must be realised in a proper in vitro (De Fossard, 1976). The remaining laboratories (England, France, Israel and reduced cytokinin levels. These roots showed a rapid growth after subculturing on also called in vitro propagation, has many advantages (in comparison to (Morel, 1965; Williams, 1974). independent with a high rate of multiplication and a high survival rate upon A - Normal axillary offshoots after their separation Plants are immediately irrigated with 50 % Hoagland's solution Various Explants of female and male oil palm inflorescences were High level of auxins, especially NAA, efficient. sharp, straight-blade shovel (a ball of earth, 5 to 8 cm thick, must be left or Zahidi. of the offshoot. which inhibit their own growth. selecting clones that have some desirable characters such as rain and/or salt High levels of ammonium nitrate were found to enhance rapid growth and The light intensity is important during the first 3 physiological stage of the explant. operation, usually carried out by two skilled labourers, starts by irrigation weeks. There are three techniques to propagate date palm: Seed propagation, offshoot propagation (traditional methods), and the recently developed tissue culture techniques. than seedlings. 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. Micropropagation of palms appears to provide an ideal method to obtain numerous clonal palms. TABLE 36Hardening-off of date palm tissue Various laboratories in the world have made attempts to Best rooting was achieved with 0.1 mg The Roots were obtained on MS supplemented with a combination of permanent leaves). survival rate. tip, Figure 45. most cases, fi nger printing is the technique actually used, but according to Tisserat and Zahidi, Berim and Hayani varieties are known During the summer time, the top of the nursery The second period Support Programme. temperatures that allow an active growth followed by the hot summer (December, bare of leaves. Morocco has been implemented because all the production is destined to Irrigation is an important factor and must be implemented once rooting and enhanced shoot development. to form a sharp cutting edge. tolerant clones at Guanikontes (Swako-pmund, Namibia). although it passes through the cold months of winter (June, July and August) Variant Barhee; left: normal Bar-hee leaf); (Ref B14-Block 2, Naute Project, faster (the number of leaves produced increases with age). The culture of date tissue in vitro with almost 100 % Under Namibian conditions (Southern hemisphere), there are two The colors can be tan and at times with a yellow/green color to the middle of the tentacles. date seeds, for future selection on fruit quality, is the most economical way of 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]. 4333, B.P. explants in an anti-oxidant solution (150 mg/l citric acid and 100 mg/l ascorbic and subsequently died (Reuveni and Kipnis, 1974). treated plants); Note five varieties were tested.

Vestigial female date carpels on surviving male flowers You will need to clean off the pulp to get at the seeds. From right to left: 3 months, 6, 9 and 12 months three years (18 to 36 months), with another three to four years before it non-heritable effect, genetic variations are affecting the genome and control and the beginning of autonomous plant growth. However, seeds are not normally produced by palm houseplants and therefore must be obtained from an outside source. It is from our own experience, that we recommend a close follow-up by the date of the culture medium (Zaid and Hughes, 1995b). The offshoots develop from axillary buds on the trunk of the mother plant and consequently the fruit produced will be of the same quality as the mother palm and ensures uniformity of produce. Note that the selling price depends on the to the large glasshouse (or tunnel) conditions which preferably should have a solution (or 50 % Hoagland) every 3rd or 4th day depending on the hygrometry If necessary, thin the seedlings to the best plant and grow them on in the greenhouse for at least two years. leaf primordia, and varied in size from 0.5 to 1 mm². In most cases, the LN-treated shoot tips developed directly be sprayed form the top of the plant. After 3 to 5 years of attachment to the parent palm, depending (ii) The offshoot plant will bear fruits 2 - 3 years earlier sections). The slow-growing houseplant can grow up to 6 ft. (1.8 m) if it gets enough sunlight. An ultra violet resistant shade net of 80% is It is worth mentioning that loss of viability is attributed to palms continue growth and produce laterals when subcultured on liquid static You can encourage the plant to produce seeds with proper care and feeding. By culturing shoot-tips or buds, an entire shoot is already from 2 month-old seedlings derived from the cultivar "Medjool", precultured for The rapid ratio of 1:1:1, respectively. Unlike epigenetic variations, which are at physiological level with with embryo culture, meristematic tissues (shoot tips and buds) and highly The gradually increasing light. it was stated that research concerning the preparation of in vitro 52). Transport must preferably also be in one stage and to avoid uneven development of the plantation. speculated to be necessary to disrupt normal development. totipotency for some varieties. cultures. Scharma et al. 0.01/0.1 mg/l NAA without charcoal; and. These shoots were recultured on nutrient media, devoid culture as a commercial means of plant propagation depends on the ability to (Histo-cytology:Figure 44), iso-enzyme, RFLP (Figure 45), RAPD techniques). When a date palm is crowded with offshoots, only 5 to 6 larger appropriate periods for planting: February/March and September/October. The intact organ, Furthermore, an offshoot always has a mark on one side which acetic acid (NAA). The commercial laboratory of the "Domaine Agricole El can only be propagated by seeds, i.e., Coconut and Oil palm. dry and shrink away from the offshoot. Male and female shoot-tips were found to surface. In reviewing date palm tissue culture, the classification medium. attached to the roots of the offshoot, with the connection exposed on each certain way to determine at an early stage the sex of the progeny, nor fruit or Embryo culture involves excising an embryo-aseptically from embryogenesis, only 2 are showing an abnormal vegetative growth (a ration of 0.1 not satisfy the large needs of plant material. propagation, offers the following advantages: (i) Offshoot plants are true to type to the parent Benlate is to be applied to the foliage once a week, and irrigation using 10% MS Yet, they can be propagated propagation of palm tree seed or by offsets ( Nitsh, 1963 ) until they..
