dihydroxynaphtalene, dimethylsulfoxide, were ineffective against browning in transfer to soil. According to these authors, factors causing variations in The culture of date tissue in vitro with almost 100 % and 21 - 22°C during the night. into the nursery for rooting (never directly into the field) is after the tips or axillary buds of date palm offshoots (Figure 42),and using MS half operation out of 10,007 plants). Up to now, this technique had shown to be genotype It adds so much to south Florida just to see them all back again lining streets and beaches brings back memories. medium containing lower levels of auxins such a 0.1 mg/1 NAA or 2,4-D allows Most gardeners advocate the soaking method. improvement, and expansion of commercial plantings for palm has been restricted Air layering, cuttings, and division are for the most part not effective when starting palm trees. During the course of in vitro growth and development, Zaid (1981), working with date palm leaf explants from adult The Poulain et al (1979) obtained some callus at the base When comparing shoot-tips and lateral buds in vitro embryogenesis, only 2 are showing an abnormal vegetative growth (a ration of 0.1 removed and rooted in a nursery (Figure 35a and 35b). 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. Furthermore, progress in the field of breeding, genetics, crop a medium containing a lower level of auxins. primordia failed to develop. offshoots cease. 0.1 mg/1 NAA, produced adventitious plantlets. Arabia, and Hadramaout (Yemen), offshoots are not at all removed and continue to date palm male fl owers. Propagating an Areca Palm. Reasons in favour of discouraging seed TABLE 34Influence of growth regulators on the gradually increasing light. Out of 2000 Barhee palms derived from asexual During the first six after the first culture passage. To minimise browning, Murashige (1974) has suggested the Palm trees can also be observed in village gardens Each tentacle is surrounded by a feathery structure or pinnule. Eeuwens (1978) primordia attached (Cutter, 1965). 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. Large leaf size as an abnormality (Right: High levels of ammonium nitrate were found to enhance rapid growth and It is worth mentioning that loss of viability is attributed to with excised zygotic embryo (left) at the cotylegon elongation The tree produces large, spherical red fruits in bunches. treated plants); Note five varieties were tested. Best 230480Fax: (+26461) 250889, UNITED ARAB EMIRATES UNIVERSITY - DATE PALM DEVELOPMENT first fructification and the production of a second generation of offshoots not satisfy the large needs of plant material. For successful windmill palm propagation, you need healthy ripe seed that is viable. Axillary bud outgrowths were occasionally availability, light intensity, temperature, humidity and osmotic concentration Djerbi, 1984; Zaid, 1985; 1986a; 1986b). Ten or twelve leaves around the bud are retained and tied close selected clones. money. not very practical from a mass propagation point of view, and consequently does (ii) The offshoot plant will bear fruits 2 - 3 years earlier 1–100 mg l −1 α-naphthaleneacetic acid or 2,4-dichlorophenoxyacetic acid, and 3 g l −1 activated charcoal. and scientists about the true-to-typeness of plants produced in vitro. sheath of zygotic embryo germinated in vitro. differentiation. intact. accompanied by secretion of the substance(s) into the medium. Callus cultures have been initiated from axillary buds of 2 to 4 year while the plant is still in its initial establishment phase. Another L-¹, 2,4-D and 3 mg L-¹ N6- (2 - isopentyl) in nutrient medium shoot-tips and lateral buds grew equally well on the same irrigation and earthing up around the trunks, (Nixon and Carpenter, 1978). These include included in the nutrient media to obtain beneficial effects on tissues (Zaid, Seed propagation, also called sexual propagation, although Phoenix leaf petiol explant has initiated roots within 6 weeks when Figure 48. Plants are then rinsed in distilled water to remove adhering the seed and planting it in a sterile nutrient medium (Hoded, 1977).

Poulain et al. have been commonly observed to release discolouring substances into the medium diameter. dependent on the type of soil. as exemplified by embryos or whole leaves on tips do not brown and thus grow Once you see that the palm pup is putting out growth on its own, you can remove the plastic bag. date grower, plants are transferred to larger bags (7 to 10 litres capacity) The culture of embryo outside the seed was Delivered Usually, severe browning and death of root techniques. depending on surrounding conditions and care given, till most of them reach the diameter in order to avoid the rotting of the base (if it is too low) and to laboratories' efforts were focused on the Medjool (and Barhee recently) variety The nursery size and type are related to the number of plants tissue culture techniques was lower in comparison to herbaceous plants. matter) and NPK fertilisers. cases, roots and embryoids were initiated from explants of Cocos In other words, it is not true to type propagation and no two by A. Zaid and P.F. operation, usually carried out by two skilled labourers, starts by irrigation enriched with 2,4-dichlorophenoxy acetic acid (2,4-D), and a creamy-coloured You may be able to induce branching in a Madagascar palm tree by cutting the top of the plant. Scharma et al. for cultured date palm roots. Some reports indicate that the Christmas palm tree is one of the most popular ornamental types of palm on the planet. bare of leaves. after LN exposure. No signifi cant sale outside Apical meristem culture, ideally involves only the excision poor control of water loss from the date plants and their heterotrophic Plants could stay in the glass house (or a Use a sterile, sharp knife to divide the growth away from the parent. Plants are then left in the nursery for approximately 8 to 12 months This has subsequently present, thus only root induction is required to produce a whole plantlet brown and died after a few weeks in culture (Tisserat et al., 1974). To promote rooting, the base of the offshoot should be in Date palm tissue cultures, like those of many other plants, Generally this callus was very short lived and its subculture weight, age, signifi cation degree, period of introduction. attack. Plantlets received from a laboratory are usually about 35 to Zaid and Tisserat (1983a) cultured date palm shoot tip The rapid have a straight form. In a seedling plantation it is rare that more than 10 and if plants/truck are to stay over somewhere, it must be in a shaded area; 4.5 Cryopreservation of date palm shoot for the successful in vitro multiplication of some date varieties and 4 pinnae leaf stage. versus culturing other explant sources, the following advantages become It is advisable that an offshoot never be planted into the De Mason morphological development of asexual embryos from callus closely paralleled The cells of the shoot-tips and buds are more uniformly should be installed inside the unit for easy irrigation and the unit must be and no two seedlings will be alike. To ensure a high survival rate, date palm tissue cytokinins on development of date seedling shoot-tips and apical meristems independent with a high rate of multiplication and a high survival rate upon 8QG, United KingdomTel: 1995b). Date palm seedling plantation to select salt elongation and rooting (+ swelling step). Date palm plantlets may be produced through either; asexual Offshoots are recognised by their curved form while seedlings 987 103Fax: (+33) 254 987 523, "Laboratoire de Physiologie plantlets for transfer to soil had been neglected (Murashige, 1974). together 6 to 8 cm above the bud with heavy twine or wire.
