Abstract:O presente trabalho foi realizado em condições de ripado, com o objetivo de avaliar o desempenho da enxertia a inglês simples, em dois tipos de porta-enxerto (pé-franco e alporquia), em combinação com três tipos de anelamento do ramo (sem anelamento, e ramos anelados duas e quatro semanas antes da retirada do garfo), em lichia. O experimento foi conduzido em delineamento inteiramente casualizado, com seis tratamentos e três repetições. Foi somente observada diferença significativa para o tipo pé-franco, que re… Show more

“…In an Australian study, Menzel et al [7] suggested that the adequate level of P in leaves for a good production was between 1.4 and 2.2 g kg −1 , as measured in branch leaves after panicle emergence in the period between May and August. Martins et al [1] recommend 0.11 to 0.22 kg of fertilizers containing 2-4% of P for lychee plants in their first year of cultivation. In Hawaii, a recommendation of 78 g of P 2 O 5 per lychee plant is reported by Menzel and Simpson [2].…”
The objective of this research was to study the effects of P fertilizers applied at time of planting on lychees' nutritional status and on plant growth. The treatments consisted of five doses of P: zero, 50, 100, 200, and 300 g of P 2 O 5 per plant, furnished by triple superphosphate. Plant diameter was evaluated during two years and the plants' nutritional status on the second year. The second year foliar levels of macro and micronutrients (with the exception of Zn) were increased by the P fertilizer. The orchard's initial development, especially during the second year, was also influenced by the fertilizer. The P doses of 164 and 158 g of P 2 O 5 per plant resulted in the largest plant diameter after the first and the second year, respectively. These doses were found to be associated with a foliar P level of <1.4 g kg −1 .

“…The rootstocks used in the experiment were eight months older than those used in the first experiment when they were 16 months old. Martins et al (2002) evaluating two types of lychee rootstocks (ungrafted and layering), belonging to the same rambutan family, observed the best results using one-year-old rootstocks (27.2%), while when the graft made on rootstocks generated by layering, the setting was practically null (0.5%). These results show that the age of the tissue (juvenility) may influence the results.…”
-The reality of Brazilian fruit farming is demonstrating increasing demand for sustainable information about native and exotic fruit, which can diversify and elevate the efficiency of fruit exploitation. Research on propagation of fruits tree is very important so that it can provide a protocol for suitable multiplication of this fruitful. Due to the great genetic diversity of rambutan plants, it is recommended the use of vegetative propagated plants. This research aimed to evaluate the propagation of rambutan by cuttings, layering and grafting, as well as seed germination and viability without storage. The results of this research indicate that this species can be successfully propagated by layering, grafting and seeds. We also observed that the germination percentage of seeds kept inside the fruits for six days were not influenced by the different substrates used in this experiment. Index terms: Nephelium lappaceum L, grafting, layering, cuttings.AVANÇOS NA PROPAGAÇÃO DA RAMBUTEIRA RESUMO -A realidade da fruticultura brasileira tem demostrando crescente demanda de informações sustentáveis sobre frutíferas nativas e exóticas, as quais possam diversificar e elevar a eficácia da exploração de frutas. Pesquisas em propagação em frutíferas tem grande importância para que se possa fornecer um protocolo para adequada multiplicação dessa frutífera. Devido a grande diversidade genética das plantas de rambutan, para estabelecimento de pomares comerciais da cultura, recomenda-se o uso de plantas propagadas vegetativamente. Este trabalho teve como objetivo avaliar a propagação de rambuteira por estaquia, alporquia, enxertia, bem como a germinação por sementes e a viabilidade no armazenamento. Pelos resultados dos trabalhos nota-se que a frutífera pode ser propagada por alporquia, enxertia e por sementes, e se existir a necessidade de armazenamento de sementes que não ultrapasse um período de seis dias e sejam mantidas dentro dos frutos, não houve diferenças consideráveis na germinação nos substratos testados neste experimento. Termos para indexação: Nephelium lappaceum L, enxertia, alporquia, estaquia.
“…Propagation of litchi can be carried out by sexual or vegetative methods. However, seeds present low viability and it is more used to obtain rootstocks and genetic improvement (Martins et al, 2001;Yamanishi, et al, 2005). Beyond this method, vegetative propagation can be performed by air layering (Franco et al, 2005;Smarsi, 2008;Costa et al, 2012;Lins et al, 2015) and cutting (Carvalho et al, 2005;Bastos et al, 2006;Koyama et al, 2014;Alves et al, 2016;Colombo et al, 2018), and this last method presents as advantages possibility of obtaining a large number of nursery plants from a single stock plant, less complexity of execution and lower cost of labor (Fachinello et al, 2005;Bastos et al, 2006).…”
A alternative to producing litchi (Litchi sinensis Sonn.) seedlings is by cuttings. However, the main drawback of using this method is related to the difficulty of rooting presented by this species. Thus, the objective of this study was to evaluate the rooting of semihardwood cuttings of litchi ‘Bengal’ at different concentrations of indolebutyric acid, with or without incision in the base. The experimental design was completely randomized with five replicates of 10 cuttings in a factorial 3X2 (three IBA concentrations: 0, 1.000 and 2.000 mg L-1; with or without incision in the base). After 126 days, the variables evaluated were: cutting survival, leaf retention, cutting with callus not rooted, rooted cutting, number of roots per cutting, length of major roots per cutting and dry weight of roots per cutting. For rooting, the IBA application was efficient only when the cuttings were not injured. In addition, there was no influence of the types of cuttings in the IBA concentrations. However, in those with incision at the base, the means were higher without the application of the plant growth regulator. Thus, the 'Bengal' litchi can be multiplied by semihardwood cuttings with incision at the base of the cuttings, without the use of IBA.
