Special attention will be given to the nursery organization in terms of plants classification according to their age, variety and development weak or distorted plants must be eliminated. Abutiate and Nakasone showed that the rate of cambial growth of the stock was an important factor in the degree of success in grafting lychee in Hawaii.
In order to ensure optimal shading and create an atmosphere that will favor the development of the young plants, the following criteria will be respected: Planting of cuttings for rooting Cuttings are stuck fairly deep cm to reduce the danger of drying and to give support.
Treating the cuttings with plant growth regulators particularly auxins has been widely practiced to increase the percentage of cuttings that from roots, to hasten root initiation and to increase the number and quality of roots produced per cutting.
On the other hand, it can be used for direct planting in the field.

In case of pine bark or coconut fiber substrate, it is recommended to wet it never saturate before putting in the clear flexible plastic bag 20 x 10 cm and lock the top of the bag to facilitate transport and further fixing.
Physiological studies on desiccation, wet storage and cryopreservation of recalcitrant seeds of three fruit species and their excised embryonic axes. Domestic and wild animals must be prevented from walking on the site in order to eliminate any risk of plant deterioration by trampling, leaves consumption or animal dejections, etc.
The raw sphagnum moss should be washed with tap water to remove excess of salts and kept in basket filled with water for hydration before use and the excess of water removed just by hand compression.
After examining the main morphological and developmental characteristics of the plant and the description of the structures and materials, including types of substrate required for the propagation of this species, the different methods for its propagation are discussed. A peculiar characteristic of litchi which is of great importance for its propagation is the fact that Venning found that the entire cambium is active only during the earliest phase of secondary growth.
Southeast Asian countries, along with Australia, use the original Chinese names for the main cultivars.
Flora del Noroeste dé México – Litchi chinensis
Actually Consultant in Tropical Fruits, E-mail: Mother plants should be nourished with recommended doses of nutrition to encourage more vigorous shoots. The propagation site must have on its proximity an independent place for storage of propagation substrata and preparation of mixtures close to the propagation general structure. Its modulation of oxidative stress, bioefficacy, neuroprotection, food application and chemoprevention potentials”.
Chinnesis unit plant is allowed to grow, where the rootstock contributes to the root system while the scion to the canopy. The mother plant blocks in the nursery should be in the sunniest situation with necessary irrigation facilities. However, up to now no universal dwarfing rootstock has been found in litchi. In the 1st century, fresh lychees were in such demand at the Imperial Court that a special courier service with fast horses would bring the fresh fruit from Guangdong.
Fourth, budwoods should be collected on the same day of grafting operation. They are also grown as an ornamental tree as well as for their fruit. In areas with high pluviometry, mrxico elimination of surface waters and of rainwater stagnation points is essential for limiting the spread of diseases that might harm the development of young plants.

Wikimedia Commons has media related to Chinensiss chinensis. Retrieved 24 November When medico stem diameter at ground height grows to around 6 cm, they are ready for grafting. Indian Journal of HorticultureNew York, v.
In grafting, bud sticks consisting of 1 to 3 buds are used. Litchi seeds are recalcitrant and highly susceptible to desiccation. Due to the limited and unpredictable activity of the cambium, which is related to the onset of leaf flushing, and since the external stem surface offers no clue as to which portion of the cambium is active, it is purely by chance that two active areas can be brought together.
The first criterion mesico selection of rootstocks is the compatibility of the rootstock with the target cultivars. Archived from the original PDF on Seed Science and TechnologyZurich, v. Plants must be free from any insect traces mainly bark drillers and from diseases. Once separated from the flesh tissue, the exposed seeds quickly lose vigor due to evaporation.
September 22, ; Accepted: Msxico and Culturev. This makes it easier to cut, easier to stick into the media, and decreases the likelihood of damage to the xylem vessels in the chinenis.
Litchi trees undergo recurrent flushing, with terminal buds alternating between rest and growth status even under constant growth conditions. The bark is grey-black, the branches a brownish-red.
Air layer operation Before air layer operation lychee tree must be well hydrated to facilitate the bark removal. Between terminal and sub-terminal cuttings, the sub-terminal is better as they normally have higher survival percentage. After being separated from the fruit and removing the whole flesh, the seeds must be sown horizontally to a depth of This will also serve as protection against pests and diseases.
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.
Acta Horticulturae SinicaBeijing, v. Propagation by grafting Grafting is an asexual propagation method that involves uniting two parts, the rootstock and the scion, from different plants into one plant. If this is not possible, put them on a surface that is concreted, covered with gravel or with a cjinensis specially made to avoid the penetration of the roots into the soil.
Therefore, after taken from the litvhi, they should be placed in wetted sand as soon as possible to force germination. However, the labels must be removed after the plant has been transplanted in order to avoid the girdling of the tree trunk. Although there is substantial increase in carbohydrates in the shoots due to girdling, chibensis fail to result in increased rooting of cuttings.
In Queensland Australia, semi-hardwood and hardwood cuttings, collected from cv. It is essential that during this period the rooting medium be kept moist as the root primordial are extremely succulent and should be favoured with an adequate supply of water in the early development. To facilitate transplanting, they should be at a distance of not less than double their length sown around cm Propagation by air layering This is the most widely used propagation method for litchi and the one which gives the most successful results.
