Flowering plants possess an unrivaled diversity of mechanisms for achieving sexual and asexual reproduction, often simultaneously. The commonest type of asexual reproduction is clonal growth (vegetative propagation) in which parental genotypes (genets) produce vegetative modules (ramets) that are capable of independent growth, reproduction, and often dispersal. Clonal growth leads to an expansi...

Rambutan tree (Nepheliumlappaceum L.) is an important but a lesser known fruit tree in Ghana and has several nutritional and medicinal uses. Efforts to establish plantation of Rambutan in Ghana to ensure its sustainable use is challenged with unavailable planting materials because the seeds are recalcitrant in nature, loses viability easily when exposed to dryness. Seeds are therefore sown dire...

strategies based on genotypic selection. It is concerned with producing improved cultivars for clonal propagation by tubers, and not with ones for propagation by True Potato Seed (TPS). This is because SCRI breeders are sceptical about the place of TPS in the highly developed markets of Europe and North America, whilst acknowledging that there is much interest throughout the tropics in TPS as a...

However, its commercial success as a biofuel plant is still elusive. Major bottlenecks for the same are significant variations in seed yield and oil content, low seed viability and germination rate. For vegetative propagation to be successful, it would require availability of quality planting material throughout the year. However, this is limited by unavailability of quality planting material a...

Numerous workers have shown that vegetative propagation of eucalypt was possible at the industrial level using physiologically and onto genetically mature plants. This kind of propagation needs the use of rejuvenated shoots which can be obtained by intense pruning, grafting and successive graftings (with a great attention to take cutting or graft on the precedent generation as soon as possible)...
