Orchid Pollination Biology
No full textOrchids and their pollinators have developed fascinating co-adaptations that promote orchid pollination. This 6-page fact sheet details the various and often strange ways that orchids attract pollinators. The kinds of insects and animals that pollinate orchids and orchids’ reproductive anatomies and processes are also covered. Written by Haleigh Ray and Wagner Vendrame, and published by the UF Department of Environmental Horticulture, June 2015.

Breeding of Orchids Using Conventional and Biotechnological Methods: Advances and Future Prospects
No full textThe domestication of plants, including ornamental plants, is an ancient tradition based on human curiosity and is the first form of plant breeding based on modern agriculture. However, recent advances in biotechnology, molecular biology, and genetic engineering, associated with better knowledge of the genome, have enabled numerous achievements to advance agriculture towards a new green revolution. In orchids, it has not been different, and recent advances in genome sequencing and the development of more sophisticated breeding techniques based on biotechnology have demonstrated their applicability for the constitution of more sophisticated cultivars. However, conventional breeding by directed crosses associated with the selection of superior genotypes has brought the greatest number of contributions to the generation of new cultivars for the flower market. The main objective of this chapter is to demonstrate this moment of transition from conventional to biotechnological breeding tools and their achievements, as well as the advances in biotechnology aimed at the production of orchid cultivars with characteristics that are not obtained by conventional breeding. In addition, it raises bigger questions and prospects about the use and applications of transgenic orchids, as well as other techniques involving targeted manipulation of DNA, such as genomic editing
Advances in Coconut palm propagation
No full textAbstract Coconut palm (Cocos nucifera L.) is one of the most important tropical species used by man, known as “tree of life”. In recent decades, with the expansion of coconut growing areas, limitations such as the occurrence of pests, uniformity of crops, adaptation to different ecosystems and others have affected the production and longevity of coconut trees. This review describes the major advances in propagation techniques of coconut palm, conventionally, by seeds and through plant tissue culture techniques from the mid-twentieth century onwards, as well as phytosanitary aspects that should be considered to mitigate the spread of pests and diseases

Sweepotato (Ipomoea batatas) and chickpeas (cicer arietinum) experiments from NS-31 Suborbital flight.
No full textThis research investigates the adaptation of sweet potatoes (Ipomoea batatas) to microgravity (through analysis of genes, proteins, and histology) and evaluates the impacts of space radiation on chickpea seeds (Cicer arietinum). The objective is to optimize crops for sustainable life support systems in space, aligning with NASA's Artemis objectives and the Brazilian space program.Resum
Genetic structure from the oldest Jatropha germplasm bank of Brazil and contribution for the genetic improvement.
No full textJatropha is a potential oilseed crop, which requires mitigating factors such as the low genetic variability of the species. The solution runs through the research of Brazilian germplasm. Attention should be given to the germplasm of jatropha the north of Minas Gerais, because this is the oldest national collection and because this region may be a regions of jatropha diversity due to selection pressure arising from environmental adversities
Influence of silicon and in vitro culture systems on the micropropagation and acclimatization of "Dwarf Cavendish" banana.
No full textIn vitro culture systems based on liquid culture media are considered to be more effective than semisolid culture medium systems. Liquid culture media systems provide better nutrient availability for plant tissues, easier culture handling, and the potential for scaling up and automation. However, in vitro liquid culture requires more careful handling due to the potential for contamination and the possibility of negative effects, such as hyperhydricity or vitrification, that hinder the growth and development of the plant material
