Flora del Noroeste dé México – Litchi chinensis

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. Propagation by cuttings Litchi is not commercially propagated by cuttings, though the method is simple and inexpensive.

Second, grafting has a higher propagation coefficient than air-layering or cutting. Generally hardwoods of current season or previous season are used. According to the quality of the substrate, it is possible to add a little phosphate fertilizer and to rectify the pH increase by adding some agricultural lime. China Agriculture Press, Handbook of environmental physiology of fruit crops.

First, budwoods should be taken from trees at the stage around initiation of new flush. Plastic bags of around 15 cm of diameter and more than 30 cm height can also be used. CientificaJaboticabal, v. Methods of grafting Various methods of grafting are available. Therefore, after taken from the fruit, they should be placed in wetted sand as soon as possible to force germination.

The most commonly used commercial method of propagation of litchi is air layering. 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 mxeico from pests and diseases and the required disinfection will kill the arbuscular mycorrhiza fungi.


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

Thin branches give rise to air layers with a poor root system and smaller chinenis which took longer to come to bearing. If we take budwoods with buds that are about to break, the bud growth of grafted scion will take place soon after grafting, while it will take much longer if we use budwoods with buds in endodormant status. The highly heterozygotic characteristic of this species prevents the commercial propagation by seeds. As a result, the scion cultivar is multiplied.

The emperor had the fruit delivered at great expense to the capital. 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.

Lychee – Wikipedia

Air layering continues being the commercial practice used in most countries for litchi propagation. It involves a vertical cut made on both the scion and rootstock, removing a strip of bark from the two parts at similar width and exposing the cambium tissue.

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.

After being separated from the fruit and removing the whole flesh, the seeds must be sown horizontally to a depth of In Vietnam, the most popular cultivar is Vai thieu Hai Duong. Effects of shading and girdling on shoot growth and photosynthesis in litchi. Too light a substrate sandy will not structure the clod of the plant properly and will be subject to frequent water deficits due to quick water draining.


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. Only in China grafting of litchis is also commercially used. 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.

These operations are not necessary in the case that the grafting process has been done in seedlings prepared on bags at the nursery, since almost no disturbance of the root system will occur during field transplant. Prior to uprooting, the seedlings should be well irrigated so that the soil and root will stick together during uprooting with minimum damage on the root system. Criteria for selection of mother plants for air layering Selected mother plants for air layering should be young preferably below 15 years of agevigorous and healthy.

Although there is substantial increase in carbohydrates in the shoots due to girdling, and fail to mexlco in increased rooting of cuttings. Conclusion Air layering continues being the commercial practice used in most countries for litchi propagation. Introduction The most commonly used commercial method of propagation of litchi is air layering.

In the case of alkaline water the pH should be corrected wit nitric, sulphuric or phosphoric acid. On the other hand, it can be used for direct planting in the field. The young plants should also be protected from sun-burning with shading net. The propagation of lychee by cuttings.
