Characteristic features of the implantation site The optimal implantation conditions are as follow: The most commonly used commercial method of propagation of litchi is air layering. The investigation linked the illness to hypoglycin Chhinensis and MCPG toxicity, and to malnourished children eating lychees particularly unripe ones on an empty stomach.
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. Handbook of fruit science and technology: Wikimedia Commons has media related to Litchi chinensis. In dry regions when chinemsis nebulizing systems have been installed it should be advisable to have humid tunnels or at least to cover the plants with plastic bags to avoid desiccation of plants during dry periods.
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 aerial part of the plant, but if mycorrhiza is used phosphoric fertilizers should not be applied to the propagation media.
litxhi Smaller bags must not be used in that case as the roots will not have enough room for developing and may go out of the bag through the draining holes. This method is most commonly used for propagating litchi as it needs much less skill and force to operate.
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. 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.
Although there is substantial increase in carbohydrates in the shoots due to girdling, and fail to result in increased rooting of cuttings. Its modulation of oxidative stress, bioefficacy, neuroprotection, food application and chemoprevention potentials”.
Retrieved 24 November Generally hardwoods of current season or previous season are used. This makes it easier to cut, easier to stick into the media, and decreases the likelihood of damage to the xylem vessels in the stem.
In Vietnam, the most popular cultivar chinnensis Vai thieu Hai Duong. Germination should normally commence within 3 days. When the root system has become firmly established and the top has attained sufficient leafy growth, the plant is ready for setting in the field. Criteria for selection of rootstocks Rootstocks contributes to the root system and exert strong effect on the vigor of the propagated litchi trees.
When the stem diameter at ground height grows to around 6 cm, they are ready for grafting. Mitra and Bose achieved 85 per cent success in rooting of cuttings with the combination of ethrel 2 x M and IBA chhinensis x M. They are adapted by developing leaves that repel water, and are called laurophyll or lauroid leaves.
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. 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.
Metabolic changes during adventitious root formation in Ethrel and IBA treated cuttings of litchi. Despite grafting can be useful for getting several advantages such early bearing, adaptability to adverse soil environment and facilitate training, more research.
Roots usually developed faster on branches with mature vegetative growth compared to recently flushed wood. Some cultivars produce a high percentage of fruits with shriveled aborted seeds known as ‘chicken tongues’. With untouched crown, the leaves are removed and potted.
A good nursery plant has a straight stem with branches future framework branches that branch horizontally at about mm high. Litchi trees undergo recurrent flushing, with terminal buds alternating between rest and growth status even under constant growth conditions. Retrieved 30 Jan Third, chindnsis grafting, rootstocks may affect many traits of the scion cultivars, such as hardiness, tree vigor and flowering time.
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 meixco the layers. A wide range of cultivars are available, with early and late maturing forms suited to warmer and cooler climates respectively. Food and Agricultural Organization of the UN.
