“…To have an idea of the importance of this genus in the expansion of world floriculture, only in the Dutch market, the largest in the world, in 2014, 121 million pots of Phalaenopsis were sold generating approximately US$ 500 million [6]. In addition to Phalaenopsis, other genera of economic importance to floriculture include the genera Cattleya, Dendrobium, and Oncidium and their hybrids [7][8][9] as well as Cymbidium and Vanda used for production of potted or even cut flowers.…”

“…Techniques involving the germination of orchid seeds under in vitro conditions are especially used in: Conservation and production of seedlings of native species; germination of seedlings from crosses aiming at genetic improvement and production of new orchid cultivars [8]; aiming at the production of protocorms in order to study somatic embryogenesis in vitro, also known as protocorm-like bodies or simply PLBs [17,22]. They can also be used for commercial propagation and seedlings production, but with high genetic variability inherent in the family Orchidaceae, including commercial groups used for flower production [8].…”

The process through induction, proliferation and regeneration of protocorm-like bodies (PLBs) is one of the most advantageous methods for mass propagation of orchids which applied to the world floricultural market. In addition, this method has been used as a tool to identify genes of interest associated with the production of PLBs, and also in breeding techniques that use biotechnology to produce new cultivars, such as to obtain transgenic plants. Most of the molecular studies developed have used model plants as species of Phalaenopsis, and interestingly, despite similarities to somatic embryogenesis, some molecular differences do not yet allow to characterize that PLB induction is in fact a type of somatic embryogenesis. Despite the importance of species for conservation and collection purposes, the flower market is supported by hybrid cultivars, usually polyploid, which makes more detailed molecular evaluations difficult. Studies on the effect of plant growth regulators on induction, proliferation, and regeneration of PLBs are the most numerous. However, studies of other factors and new technologies affecting PLB production such as the use of temporary immersion bioreactors and the use of lighting-emitting diodes have emerged as new tools for advancing the technique with increasing PLB production efficiency. In addition, recent studies on Phalaenopsis equestris genome sequencing have enabled more detailed molecular studies and the molecular characterization of plantlets obtained from this technique currently allow the technique to be evaluated in a more comprehensive way regarding its real applications and main limitations aiming at mass propagation, such as somaclonal variation.

“…The pollen grain storage is of special interest when natural flowering of the parents is difficult. In floriculture, this is especially interesting for the following reasons: the production of new cultivars is based on the use of hybridization techniques, with crosses between elite genotypes, followed by progenies evaluation and selection (Cardoso et al, 2016;Cardoso, 2017) and crosses between species with different flowering periods may result in F1 hybrids with natural flower production in more than one season per year, or even outside the flowering period of their parents (Gomes et al, 2003;Giovannini et al, 2015).…”

The determination of viability and the preservation of pollen grains are useful tools for breeding of ornamentals, especially when the synchronization of flowering between species or cultivars does not occur naturally. Thus, the objective of this study was to characterize the flowering and to evaluate the preservation and maintenance of the viability of pollen grains in cultivars of amaryllis (Hippeastrum sp.) subjected to three storage temperatures. Anthers of five cultivars of amaryllis were collected from 12 to 24 hours after anthesis. One part of the anthers was immediately used for germination tests using in vitro germination in culture medium and the other part was stored at temperatures of 25, 8 and-20 °C. Pollen grains were germinated in culture medium at 0, 20, 75, 125, 165, 205 and 245 days after storage. All cultivars of amaryllis showed an accelerated loss of viability at 25 °C storage temperature. The 'Bull' cultivar showed higher recalcitrance to cold-storage, while 'Intokazie' and 'Pink Panther' cultivars showed higher longevity and higher percentage of germination along storage. The temperature of-20 °C resulted in the best responses for the maintenance of the integrity and preservation of the viability of pollen grains of different cultivars of amaryllis.
