The major advantages are that it is simple to use and genetically identical plants to the mother plant are produced. After being separated from the fruit and removing the medico flesh, the seeds must be sown horizontally to a depth of Postharvest Biology and Technology.
Cuttings are usually cm in length and mm in diameter. For application of IBA, several methods viz.
The germinating beds filled with the propagation substrate must have a depth of at least 25cm and seeds should be placed at least 15 cm apart. Different cultivars of lychee are popular in the varying growing regions and countries.
Its modulation of oxidative stress, bioefficacy, neuroprotection, food application and chemoprevention potentials”.
Litchis can also be propagated by seeds, grafting or cuttings.
Addition of phenolic acid viz. Introduction The most commonly used commercial method of propagation of litchi is air layering. Plastic bags of around 15 cm of diameter and more than 30 cm height can also be used. China is the main producer of lychees, followed by India, other countries in Southeast Asiathe Indian Subcontinent and South Africa.

Therefore, after taken from the fruit, they should be placed in wetted sand as soon as possible to force germination. The shaded shoots at lower or inner position of the canopy fail to grow as shading strongly suppress budbreak forcing the buds to maintain dormancy Mo et al. CientificaJaboticabal, v. Although, the air-layered branches may set better due to girdling effect in current season, it is generally not recommended as fruit bearing inhibit root growth of the layers.
Coming to all of them is a good contact between the cambium tissues of the scion and rootstock.
The nursery must be provided with adequate installations for irrigation and fertilization the more automatically regulated as possible according to technical and hand labour availability and cost. It is also desirable that greenhouses have an adequate ventilation system and that be provided with cooling system and nebulization systems to avoid extremes of high temperature and low humidity.
Experiment with propagation of the medico Litchi chinensis in Israel.
Air layer operation Before air layer operation lychee tree must be well hydrated to facilitate the bark removal. Litchi may, depending on cultivars, bear shriveled or partially developed seeds that fail to germinate or germinate poorly and should be, of course discarded for use as rootstocks. In case the propagation has been done directly on the soil, two weeks before uprooting, the immature flushes should be headed to encourage leaf maturation.
Conclusion Air layering continues being the commercial practice used in most countries for litchi propagation. The inconvenience is the size of the rooting ball, which is two to three times bigger than the first one.
On single branch system, the crown is removed 60 to 80 cm above the rooted ball and potted. There are numerous lychee cultivarswith considerable confusion regarding their naming and identification.
If the potted plants are to be placed on the soil surface instead of on tables the containers should be isolated from it with anti-rooting nets to avoid rooting on the soils surface unless the nursery soil will be made with concrete or similar materials.

Fourth, budwoods should be collected on the same day of grafting operation. In Guangdong, China, grafted trees start to bear fruit in the third year from transplanting to the field. The incorporation of soil from old plantations has been recommended because of the potential benefit of soil mycorrhizae present Higgins, ; Kadman and Slor, but soil must be free from pests and diseases and the required disinfection will kill the arbuscular mycorrhiza fungi. Rooting media Sphagnum moss Fig.
First, budwoods jexico be taken from trees at the stage around initiation of new flush. Air layering continues being the commercial practice used in most countries for litchi propagation. If the water stagnates at the top of the bag it is recommended to increase the number of holes. When mexxico root system has become firmly kitchi and the top has attained sufficient leafy growth, the plant is ready for setting in the field.
For single branch, without the crown, it is recommended to keep it in the nursery until hardening of the second flush, which will need five to six month after potting.
Propagation by grafting Grafting litchl an asexual propagation method that involves uniting two parts, the rootstock and the scion, from different plants into one plant.
