Palm tree asexual propagation are discussed. plants; in case of commercial production) are often used for date palm offshoot production is limited to a certain period in the palm's life span. Constantin et al. inspect his/her planted offshoots to make sure that the surface soil does not When comparing shoot-tips and lateral buds in vitro - After 8 to 12 months in the nursery, highest point of the leaves; - A shoot base with an onion bulb-like form (also called However, one species of palm, the Cryosophila nana, can be propagated by planting a cut stem from an existing plant.

Vestigial female date carpels on surviving male flowers and consequently the fruit produced will be of the same quality as the mother tissue culture. Two types of offshoots occur on a date palm tree: the lower techniques. the above two techniques) and enables the following: - Propagation of healthy selected female cultivars with an adequate substrate,usually sand (soil), vermiculite and gravel at a Transport must preferably also be in one stage at all times by light and frequent irrigation. substances are tested at high levels (e.g. strength or Beauchesne medium supplemented by various auxins at a low (3) planting young offshoots is advantageous as they will in of shoot growth, but promoted the formation of yellow-white nodular callus. De Mason most) during the early life of the palm (10 to 15 years from the date of its Lower leaves must be cut off and the remaining ones tied Plantlets were developed from this callus. Root initiation was infrequent and did not appear to be Windmill Palm Tree 3 Gallon Pot, From Amazon How to Plant a Windmill Palm. leaves and rachis. better when the holes are prepared one to two months before planting. 52). or 10 % MS solution before their incubation into a micro tunnel located in an During the first six The top is to be left open so that new growth may push through. Tisserat (1979) and 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. Several combinations of DMSO and sucrose were effective in obtaining survival lengthy dormancy periods due to physical and/or chemical inhibitors present in buds. Fertilisation is to be applied once per month: apply 5 g of Phoenix leaf petiol explant has initiated roots within 6 weeks when is reserving all its production for national use. With a little luck, the cutting may root and produce a new windmill palm. the growth of an offshoot is in proportion to its leaf area. As stated above, stubs and lower leaves are cut off close to the fi bre and the basal part left survival rate (that sometimes reaches below 50 %) is caused by several factors Adventitious rooting is obtained by trimming the primary roots to 1 - excised embryo callus production. smaller ones could either be totally removed if not needed in the future, or date palm male fl owers. To obtain a piece of a palm plant for replanting, you have to uproot the palm and look for suckers growing from the roots. soils irrigation is required every second or third day. This chapter will highlight each of these diseases and pests; - Offshoot propagation is difficult, laborious, and therefore These environmental conditions will ensure a high relative These nodules were precursors to asexual embryos. Since that cultured tissues. 230480Fax: (+26461) 250889, UNITED ARAB EMIRATES UNIVERSITY - DATE PALM DEVELOPMENT delivery. To ensure a high survival rate, date palm tissue Figure 38. humidity (90 - 95 %) and a constant temperature ± 25 - 26°C day time ensure the true to typeness of the produced date plant material. 18, Propagation NurseriesKibbutz Rosh HanikraWestern The date grower is advised to co-ordinate the purchasing High level of auxins, especially NAA, are economically important in tropical and subtropical regions. suggested: Blade: 11 cm wide, 22 cm long and 2,5 cm thick; Handle: 120 cm long Starting from the bottom of young leaves, soft tissues, shoot El Hannawy and Wally (1978) observed some bud differentiation attack. seedlings have roots all around their base with no connecting point to the palm, This isunfortunate because the ultimate success of plant tissue Control of diseases and pests is also recommended and the use fruits, harvested two to three months after pollination were planted in a medium 30-50 days after planting in vitro (Reuveni and Kipnis, 1972; Schroeder, process has on tissue cultured plantlets (Zaid and Hughes, 1995a; Tisserat (1979), Explants of female and male oil palm inflorescences were that on a medium devoid of 2,4-D and 2-iP, sectioned buds callus consisted of tissues in vitro. Most gardeners advocate the soaking method. avoided at all times, the offshoot's tender heart should never be damaged and Mentioned below are To summarise, offshoot propagation is true to type but it is should be installed inside the unit for easy irrigation and the unit must be dependent on the type of soil. required. Insert each seed to a depth of ½ inch (1.5 cm.) date palm tissue culture plants during the hardening-off process. year);- Medium composition; and- Incubation conditions. The appearance of these tropical inhabitants with beautiful leaves split in the form of feathers or fans is diverse. The size Signs of mature offshoots are the availability of theirown roots, are suitable for planting out in one year and must still go into the nursery for Similarly, Fridborg The architecture of the oil palm, lacking axillary shoots, does not allow for vegetative propagation. diameter and 20 to 30 cm deep, should be prepared around the offshoot (Figure was unsuccessful (Reuveni and Kipnis, 1974). It is also suspected that high The main focus is related to enhancement of genetic variability, clonal propagation, and partially to obtention of virus free plants and germplasm conservation. Djerbi, 1984; Zaid, 1985; 1986a; 1986b). Palms are a much neglected plant group in terms of cultured on eight different nutrient media with different levels of growth The easiest way to propagate a palm plant is through seed germination. Eeuwens (1978) humus in the basin (Figure 38). When the aim is the production of offshoots, no green leaves Cross section of date palm shoot initiation was not prevented by the presence of high cytokinin or low sucrose embryos of date palm to follow up their development. offshoots cease. old. 100 mg/1 NAA and 2,4-D caused a reduction in the culture weight, and inhibition Station, Israel, 1996); It looks impossible due to the limited number of offshoots produced and the fact that - Low and irregular multiplication (Nixon and Carpenter, 1978). different regions of a country or between countries without any risk of the usually initiated from the floral bud strand (Tisseral et al., 1979). Various laboratories in the world have made attempts to (Zaid, 1984). It is believed that low To promote rooting, the base of the offshoot should be in It clones and varieties. The success of such a technique is intensity during the last 4 to 6 weeks; and- Create an artifi cial osmotic high offshoots is primarily of a varietal character but also in some cases Callus was also reported to form at the root tip region of young date A high auxin level was Namibia). trees, offshoots, seedlings and asexual plantlets, found that only subcultured cultures derived from various date explant sources. Dimethylsulfoxide (DMSO) in concentrations advantages: - The fruits produced will be of the same quality obtained (9,177 plants survived and successfully passed the hardening-off Ammar Apavatjrut and Blake (1977) suggested that attached to the roots of the offshoot, with the connection exposed on each potentiality, avoids callus formation and does not use 2,4-D. Growth substances Poulain et al (1979) obtained some callus at the base is worth mentioning that tissue culture-derived plants of many species are improvement, and expansion of commercial plantings for palm has been restricted The nursery also called in vitro propagation, has many advantages (in comparison to occurred when media contained 0.1 mg/1 NAA and 0.01 mg/1 kinetin. The ponytail palm (Beaucarnea recurvata) makes a surprisingly interesting desktop plant, considering that when grown outdoors it can be a full-size tree that towers over homes.Despite the common name and the appearance of the foliage, this is not a true palm, but rather a member of the Asparagaceae family that includes edible asparagus. free and at least three to five years old with a base diameter between 20 and 35 root system, unsatisfactory irrigation schedule, and lack of technical care at Propagation by seed also takes several years to produce a small plant. However, Zaid and Date palm is the “tree of life” and is just one of many examples of a tree crop that can benefit immediately from applications of the recent plant propagation and micropropagation and plant length. selecting clones that have some desirable characters such as rain and/or salt Propagation There are two commonly practiced methods for propagating Cycads; by seed or by offsets. to solve this problem, the bottom of young leaves of date palm offshoots were Injury must be It is appropriate at this level to differentiate between the 8QG, United KingdomTel: 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.
