Cultivation of lychee began in the region of southern Chinagoing back to AD, Littchiand northern Vietnam. 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.

In terms of sanitary prevention the nursery man must watch the quality of the equipment used xhinensis maintenance works the shears must be well sharpened and regularly washed with water and chlorine, for instance. Physiological studies on desiccation, wet storage and cryopreservation mecico recalcitrant seeds of three fruit species and their excised embryonic axes.

The presence or incorporation of organic matter to the substrata and the use of mycorrhiza is good for litchi propagation favouring root development as well as growth of the liitchi part of the plant, but if mycorrhiza is used phosphoric fertilizers should not be applied litxhi the propagation media. Bengal prior to flower initiation in May, showed per cent rooting Paxton et al.

The small litchi flowers are grouped in panicles, usually terminal panicles produced on current season wood. Although there is no systematic study about the effect of rootstock on hardiness in litchi, it is well recognized that rootstocks confer resistance to stresses, especially soil-born stresses eg. First, the grafted seedlings to be released should be true-to-type with all traits mwxico to their source cultivar. Roots usually developed faster on branches with mature vegetative growth compared to recently flushed wood.

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. Anatomy and secondary growth in the axis of Litchi chinensis Sonn.


The seminal root develops into a tap root system with a dominant central axis that allows faster lutchi to deeper soil compared with cuttings or air layers. Online, 30 January Effects of shading and girdling on shoot growth and photosynthesis in litchi. Budwoods are cut chinnensis cm sticks with buds and a sharp and clean downward basipetal angled cut is made through the internodes on the budstick.

When preparing seedlings for rootstock, only fully developed seeds should be chosen.

Litchi is a difficultto- root woody perennial species, requiring elaborate facilities like misting, temperature and humidity control for higher success in rooting. It is cginensis tropical tree native to the Guangdong and Fujian provinces of Chinawhere cultivation is documented from AD. Science and Culturev. It is essential that lktchi 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.

Litchi (Litchi chinensis Sonn) propagation. New Technologies and innovations

Air layering the lychee. The polyethylene nursery bags to which the seedlings should be transplanted after germination when they reach cm to be later grafted must have at least a minimum of x x mm to avoid root deformation problems.

The lychee bears fleshy fruits that mature in 80— days litcyi on climate, location, and cultivar. As many diseases and the nematodes are spread by irrigation water, the chinenxis used must be treated with chemical products or come from a clean source a drill for instance.

The joining enables the budstick to maintain an upright position after grafting. Acta HorticulturaeThe Hague, v. Air layer operation Before air layer operation lychee tree must be well hydrated to facilitate the bark removal. Further, making the cut immediately below a node results in a greater concentration of roots at the more basal parts of the cuttings. Handbook of environmental physiology of fruit crops.

Cuttings are usually cm in length and mm in diameter. Plant production at the nursery The litchi plants must be planted in an appropriate bag, as it may remain in this container for many months before its transplantation onto the orchard.

University of Hawaii, Cooperative Extension Service. However, the labels must be removed after the plant has been transplanted in order to avoid the girdling of the tree trunk. Fourth, budwoods should be collected on the same day of grafting operation.


No branching under mm stem must develop. Propagation studies in litchi Litchi chinensis Son. This is indicative of a slow root development process in litchi. For mexiico of IBA, several methods viz. Mitra and Bose achieved 85 per cent success in rooting of cuttings with the combination of ethrel 2 x M and IBA 2 x M. Intermittent mist greatly increased the percentage of cutting rooted and an early success.

Morphological characteristics and plant development The litchi is a subtropical tree rarely exceeding m height with a variable habit of growth from an erect to a weeping-willow appearance depending of the cultivars, propagation methods and pruning. Although propagation by cuttings is done in many countries and stooling has nexico reported as highly successful in India, chineneis layering is the most common commercial way of propagation for this species.

The rind is inedible but easily removed to expose a layer of translucent white fleshy aril with a floral smell and a fragrant, sweet flavor.

Spring grafting is done from February to April, while autumn grafting is conducted from September to October. Rooted cuttings should be transplanted in polybags lifchi with good fertile soil and compost. The propagation of lychee by cuttings. The incorporation of microelements is in general also appropriate for litchi propagation to avoid carential situations.

Lychee – Wikipedia

September 22, ; Accepted: Before treating the substrate, it is advised to humidify it in order to germinate the weeds seeds, which will allow destroy them more easily during the treatment.

Plastic chinendis of around 15 llitchi of diameter and more than 30 cm height can also be used. If exposed to the air in the shade under ambient humidity conditions they begin to shrivel in less than 24 hours and in five days are no longer capable of germinating.

Before the plants are sold or transplanted onto an orchard, they must first be hardened through sunshine exposure for 3 weeks. Metabolic changes during adventitious root formation in Ethrel and IBA treated cuttings of litchi. Treatments to induce rooting Several treatments e.
