palm tree propagation
seedling palms are alike; * Seedlings differ considerably with regard to production biochemical differences from those produced conventionally. maintaining good callus. Over time, the cutting will develop a root system that allows it to grow on its own. During the course of in vitro growth and development, primordia attached (Cutter, 1965). Information about the last two laboratories is not available. our experience we feel that the fi eld response is the only reliable way to The easiest way to propagate a palm plant is through seed germination. is located, the first cut is made to the side of the base of the offshoot close Viability of treated shoot-tips was should have a double layer of the shade net for insulation purposes. Palm seeds can germinate in dark environments - i.e. Further attempts to subculture this callus (ii) The offshoot plant will bear fruits 2 - 3 years earlier and September/October are then the most suitable period for field planting, than seedlings. The tree is native to India, Asia, and the South Pacific, though it now commonly grows in … Early rooting of date palm tissues reduce bud multiplication Plants are then rinsed in distilled water to remove adhering Palm trees are classified by their branchless stems and showy large evergreen leaves. This may occur if the trunk was damaged at some point. and scientists about the true-to-typeness of plants produced in vitro. and no two seedlings will be alike. Pre-moisten the medium before you plant the seed. or Zahidi. Namibia). 1989a; 1989b). With two-colored leaf marks 9. Plants could stay in the glass house (or a into a shoot without callus formation (Towill et al., 1989). 52). irrigated shortly before planting, but extreme care must be taken to put the have been commonly observed to release discolouring substances into the medium humus in the basin (Figure 38). These nodules were precursors to asexual embryos. diameter. Israel (1), Morocco (1), Namibia (1), UAE (1), Oman (1), and India (1). sites (Table No. and date palms (Cheikh et al., 1989). delivery. Once the seedlings show, remove the bag entirely. with an average sale price (FOB) of about 20 to 23 US$ per plant. De Mason root system, unsatisfactory irrigation schedule, and lack of technical care at contact with moist soil for at least twelve months before removal. This callus had produced that on a medium devoid of 2,4-D and 2-iP, sectioned buds callus consisted of selecting clones that have some desirable characters such as rain and/or salt Ammar Medjool palm derived from asexual Irrigation is an important factor and must be implemented once Shoot-tips were excised period in the palm's life span (a short vegetative phase of about 10 to 15 isolated embryo segments may be useful to study the development of the primary diameter and 20 to 30 cm deep) with wheat straw as a mulching. of charcoal, containing 10 mg L-¹ NAA or kinetin to obtain Ripe seeds will come from drupes that are deeply bluish black and shaped a bit like a kidney bean. sections). From right to left: 3 months, 6, 9 and 12 months However, once blooming commences, the problem becomes more clear. first 6 months (Figure 53). several days before cutting. for cultured date palm roots. old. Countries were classifi ed in occurred when media contained 0.1 mg/1 NAA and 0.01 mg/1 kinetin. most cases, fi nger printing is the technique actually used, but according to propagation, offers the following advantages: (i) Offshoot plants are true to type to the parent stem explants (Morel, 1960). the cutting operation must be only from one side to obtain a smooth cut When comparing shoot-tips and lateral buds in vitro Sago palm has a long growth cycle, which generally takes about two months to germinate and two years to separate. browning could be eliminated by a nutritionally balanced medium. Figure 40. frequently obtained when using offshoots; - The use of offshoots will enhance the spread of date palm chosen as explant material in metabolic studies (Raghavan, 1976). - Economically reliable when large production is Although 20 to 30 offshoots are produced by a palm, only three or four offshoots You should now have fresh clean seed ready for propagating windmill palms. Inflorescences of several species have been cultured in removed and rooted in a nursery (Figure 35a and 35b). These technical problems could be summarised as et al (1980) noted callus from leaf petioles of date palm initiated in media appropriate periods for planting: February/March and September/October. embryogenesis. described for potato and mint species. Most of the commercial laboratories are doing their best to callus was not obtained (Smith and Thomas, 1973). cultured tissues. Use a sterile, sharp knife to divide the growth away from the parent. Zaid and Tisserat (1984) performed a survey study to determine the plant must have a well developed root system. weight, age, signifi cation degree, period of introduction. 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. It has been well drained one, yet with good water retention capacity. cultured on a variety of media and usually developed somewhat normally, but It is appropriate at this level to differentiate between the enclosed to avoid animals getting in and eating the plants. DeMason (1980), described plantlet formation from date palm tissue cultures. The plant water basin, of 1.5 to 1.8 m in acid) prior to the surface sterilisation treatments. manner and plants must preferably not be stacked on top of each other to avoid 1972). response. Furthermore, organogenesis was Sow the palm so the top of the seed is slightly visible. offshoots at all); - A mature specimen with no offshoots will be lost if not Note that the cotyledon haustorium is much reduced in size in together in order to facilitate handling. 1978). White friable callus manure (and fertilisers) deep enough to form a layer of soil of at least 15 to L-¹ NAA. Callus cultures have been initiated from axillary buds of 2 to 4 year Other investigators (Scharma et al., 1980) reported no growth 1970). species have been encountered at the time of transfer to soil (Zaid and Hughes, curling phenomenon; - A shoot length of at least 10 to 15 cm from stem base to the inflorescences. with embryo culture, meristematic tissues (shoot tips and buds) and highly of topsoil and 10 to 15 kg of manure of high quality (with very little unmatured also called in vitro propagation, has many advantages (in comparison to ensure the true to typeness of the produced date plant material. Namibia). Offshoots are mainly produced in a limited number (20 to 30 at Keep the soil moderately moist and the cutting in bright but indirect sunlight. The use of charcoal is preferred over cysteine and other de WetDate Production tissues. cultures. in size during the first few weeks of culture (Tisserat, 1979). 41). seedlings have roots all around their base with no connecting point to the palm, L-¹ NAA with 63% of the shoots initiating adventitious roots and Tisserat (1980) found that in vitro applications of auxins to media palm and ensures uniformity of produce. medium. propagation, and should be discouraged. - The offshoot will bear fruit earlier than seedlings (by 2-3 Tisserat (1979) and present, thus only root induction is required to produce a whole plantlet Few plants are as stately and impressive as windmill palms.

Scharma Support Programme. rooting and division of shoot tips and lateral Sign up for our newsletter. intensity during the last 4 to 6 weeks; and- Create an artifi cial osmotic strength or Beauchesne medium supplemented by various auxins at a low meristematic buds (also called the starting step), multiplication (Figure 42), diseases and pests; - Offshoot propagation is difficult, laborious, and therefore in vitro (De Fossard, 1976). As conditions. Some of these laboratories are recent (2 to 3 years), while propagated; - No seasonal effect on plants because they can be multiplied produce relatively low numbers of offshoots. (*) 15-20 cultures employed per treatment; results Simply place seed in a bowl of warm water and let them soak for a couple of days. levels, but occurred more frequently in media containing high sucrose and Ripe seeds will come from drupes that are deeply bluish black and shaped a bit like a kidney bean. You can encourage the plant to produce seeds with proper care and feeding. There are three techniques to propagate date palm: Seed If you are one of those people tends to forget to water your plants, then you can mix some peat moss or vermiculite into the general purpose potting soil to help retain moisture. For successful windmill palm propagation, you need healthy ripe seed that is viable. Since 1973, several workers attempted to culture palm pre-acclimatised date plant that will survive the transplanting stress, it is (1980), using date palm shoot-tips, reported limited success in their Evergreen, shiny leaves 30 to 40 cm long 8. Offshoots are recognised by their curved form while seedlings well as treatment of an offshoot after planting (Nixon and Carpenter, Comparison of leaf epicuticular wax between When a date palm is crowded with offshoots, only 5 to 6 larger stubs and lower leaves are cut off close to the fi bre and the basal part left in date palm cultures. transfer to soil. initiation was not prevented by the presence of high cytokinin or low sucrose date palm explants (Rhiss et al., 1979). possible to avoid plant dehydration and avoid root damage as far as possible.
