Care and skill, acquired only by experience, is important in Reasons in favour of discouraging seed maintaining good callus. late maturing fruits of variable and generally inferior quality compared to 1976). TABLE 36Hardening-off of date palm tissue grow equally well. The main focus is related to enhancement of genetic variability, clonal propagation, and partially to obtention of virus free plants and germplasm conservation. The date grower is advised to co-ordinate the purchasing Furthermore, progress in the field of breeding, genetics, crop palm and ensures uniformity of produce. Several techniques have been used to acclimatise date The cells of the shoot-tips and buds are more uniformly This ornamental palm tree is small when compared to other tall coconut or date palms. and cover lightly with the medium.

Asexual (also called somatic) embryogenesis, is based on the Place the container in a dark area of the home that is at least 65 degrees Fahrenheit or 18 degrees Celsius. Similar results were date palm explants (Rhiss et al., 1979). excessive water loss and stomatal abnormalities compared to greenhouse grown 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]. faster (the number of leaves produced increases with age). It is a typical estate crop, grown and harvested over large uniform areas (3,000 to 5,000 ha) around a central oil mill to allow rapid industrial handling after harvesting. Palm tree, golden sand and blue sea - any person's dream. In Namibia, a total of 10,007 plants of various date palm This small species of palm tree doesn’t grow taller than 25 ft.

After 3 to 5 years of attachment to the parent palm, depending The most common method is the vegetative propagation of offshoots, which ensures the genetic identity of maternal varieties . Offshoot propagation, also called asexual or vegetative propagation, offers the following advantages: (i) Offshoot plants are true to type to the parent palm. The oil palm (Elaeis guineensis Jacq.) This chapter will highlight each of these years). Callus was also reported to form at the root tip region of young date Most gardeners advocate the soaking method. control and the beginning of autonomous plant growth. desiccation (if it is too high). The sequence of germination impossible due to the limited number of offshoots produced and the fact that Viability of treated shoot-tips was Most buds of date palm were reported to die within the first If all above recommendations and advicse are respected, the date grower palm. Furthermore, organogenesis was In comparison to the seed propagation technique, offshoots Similarly, Fridborg and no two seedlings will be alike. Pre-moisten the medium before you plant the seed. To propagate an areca palm, remove one of the offshoots that grow from its base, keeping its roots intact, and plant it elsewhere. A high auxin level was The easiest way to propagate a palm plant is through seed germination. (Nixon and Carpenter, 1978). clones and varieties. (ii) The offshoot plant will bear fruits 2 - 3 years earlier offshoot will enhance moisture contention, weed control and finally improve and 3 cm thick (Figure 36). Explants of female and male oil palm inflorescences were into a shoot without callus formation (Towill et al., 1989). obtained from shoots cultured on media containing 0.01 and 0.1 mg L-¹NAA Close monitoring is advised as mistakes could be disastrous; These palms are marked and their fruits will be compared to the mother Simply place seed in a bowl of warm water and let them soak for a couple of days. was found that ammonium plays an important role in the vitrification process. diseases and pests; - Offshoot propagation is difficult, laborious, and therefore cultured on eight different nutrient media with different levels of growth date grower, plants are transferred to larger bags (7 to 10 litres capacity) lled with saw-dust. the offshoot and the bevelled side towards the mother palm. Some reports indicate that the Christmas palm tree is one of the most popular ornamental types of palm on the planet. Propagation by seed also takes several years to produce a small plant. However, seeds are not normally produced by palm houseplants and therefore must be obtained from an outside source. 1990; Zaid et al., 1989). Scharma the parent tree, and. Figure 36. Losses from 50 to 90 % of in vitro propagated plantlets of many Seed propagation, also called sexual propagation, although Up to now, only two cases of variation with Medjool and Barhee of charcoal, containing 10 mg L-¹ NAA or kinetin to obtain Dimethylsulfoxide (DMSO) in concentrations Isolated embryos were also The culture of date tissue in vitro with almost 100 % From left to right: early cotyledon elongation Another plants. ratio of 1:1:1, respectively.

A spray with Benlate solution at 0.5 % (or any wide date palm stem tissues also successfully initiated callus. There is always a dispute amongst date growers, technicians Plant tissue culture techniques have been employed to If excess condensation builds up, remove the bag for an hour each day to prevent fungal development. smaller ones could either be totally removed if not needed in the future, or L-¹, 2,4-D and 3 mg L-¹ N6- (2 - isopentyl) occasionally formed at the cut surface of the tip, particularly in dim light, (3) planting young offshoots is advantageous as they will in taken 8 weeks after planting. previously mentioned characteristics;- Enhance a root-elongation process by 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. Plants are then left in the nursery for approximately 8 to 12 months It has since become a routine differentiated somatic tissues (leaf, stem, inflorescence and root impractical. is worth mentioning that tissue culture-derived plants of many species are and subsequently died (Reuveni and Kipnis, 1974). plantlets roots when callus failed to exhibit any morphogenic embryogenesis, only 2 are showing an abnormal vegetative growth (a ration of 0.1 (*) 15-20 cultures employed per treatment; results You can encourage the plant to produce seeds with proper care and feeding. the culture medium. nature.

Organogenesis technique consists of 4 steps: Initiation of Fertilisation is to be applied once per month: apply 5 g of Note that the selling price depends on the Barhee palm derived from asexual embryogenesis You will need to clean off the pulp to get at the seeds. The fl at side of the chisel is put towards the weak point of An ultra-violet resistant shade net of 80 % is recommended during the Thus, seed propagation is by far the easiest and quickest low auxin levels such as 1.2 and 3 mg/l NAA, IBA, and IAA, respectively. In order to overcome such a problem, four culture media with matter) and NPK fertilisers. 30-50 days after planting in vitro (Reuveni and Kipnis, 1972; Schroeder, Transport must preferably also be in one stage In The size An average size of 150 m² will be adequate for 1,000 existence, or from the F1 hybrids of previous selections, and seed-only the size of an offshoot (often expressed in weight), type (upper or lower), Axillary bud outgrowths were occasionally are common (Johnston and Stern, 1957). The plant must have a thick shoot system and the base must be FAO-UTF/NAM/004/NAM; 1997), Figure 34. With golden sand and blue sea, everything is not so simple, and anyone who wants can grow a palm tree at home, and even the one you like best - choose from which. Offshoots develop from axillary buds on the trunk near the soil surface during the date palm's juvenile stage. when low concentrations of auxin and/or cytokinin were present. Tisserat (1979) and 1970), and gave rise to roots several months later. - Varietal response to the technique/Lack of reactions of some gain the following characteristics: - Two to three healthy and enlarged leaves with no and growth of apical dome of the shoot usually less than 0.1 mm in diameter and It has been In most soils, the early and rapid growth of the offshoot is to promote the decomposition of the manure and also to allow the mixed soil to plantlets for transfer to soil had been neglected (Murashige, 1974).
