“…Both conservation and restoration are a priority for plants with desiccation-sensitive seeds (Wyse et al 2018), which are highly abundant in humid ecosystems such as tropical rainforests (Wyse and Dickie 2017). Desiccation-sensitive seeds are characterized by high water content at dispersal, rapid germination, and short longevity (Berjak and Pammenter 2013;Pelissari et al 2018); hence, they cannot be stored conventionally in the long term (Hong and Ellis 1996). The potential climate change consequences, such as extremely dry and hot soil conditions of forest ecosystems worldwide (Allen et al 2010;Walck et al 2011), might negatively affect the highly degraded and fragmented Mexican tropical rainforest (Challenger and Soberón 2008).…”

Effects of seed priming on germination and seedling growth of desiccation-sensitive seeds from Mexican tropical rainforest

Seed priming increases the vigor of seeds and seedlings through metabolic and biochemical processes occurring during controlled hydration, followed by dehydration. In the field, seeds are exposed to hydration-dehydration events in and on the soil after dispersal, as in seed priming. Nevertheless, seed priming has been sparsely tested on desiccation-sensitive seeds, which are vulnerable to climate change effects. We evaluated the effect of two priming methods on seeds from two tropical rainforest species: Cupania glabra and Cymbopetalum baillonii. For hydropriming, the seeds were fully hydrated and then dehydrated to three dehydration levels. For natural priming, the seeds were buried for 12 days in either closed forest or forest gap. Primed seeds were sown in 1% agar medium and placed in an environmental chamber. The growth of the seedlings from the highest germination priming treatments was evaluated for 1 year in the field. Our results showed that for C. glabra and C. baillonii, hydroprimed seeds varied in their germination response, depending on the degree of their dehydration. However, for C. baillonii, hydropriming seems to invigorate seeds, compared to non-imbibed seeds of the same dehydration level. Natural priming increased germination speed in both species without any difference between closed forest and forest gap. Moreover, seeds with natural priming had a higher final germination percentage than seeds with hydropriming. Seedlings from seeds with natural priming showed a higher growth rate than the controls in both species, whereas hydropriming produced a similar effect in C. glabra. Both priming methods could be used for restoration practices with the studied species, natural priming being a novel method. The ecological implications of priming in desiccation sensitive seeds are discussed in this study.

A busca por inovações tecnológicas é uma importante ferramenta de auxílio para o planejamento da conservação das espécies florestais e seus produtos não madeireiros. Este trabalho objetiva realizar um estudo de prospecção científica e tecnológica do uso e do potencial de sementes florestais. Para a busca dos artigos, foram utilizadas as plataformas Scopus e Web of Science. As análises estatísticas foram geradas com o auxílio do pacote Bibliometrix do software R. As patentes foram prospectadas e analisadas usando-se o Orbit Intelligence. Foram mapeados 229 artigos e 387 documentos de patentes. A China é o principal detentor das patentes, incluindo produtos patenteados a partir de espécies florestais brasileiras. Embora o Brasil apareça como um dos países depositários, com destaque para as espécies nativas, ele não foi o país de origem de nenhuma patente da pesquisa. As patentes foram desenvolvidas principalmente para atender às indústrias de alimentos, de medicamentos e de cosméticos.

“…The seeds of Eugenia are recalcitrant (desiccation sensitive) (e.g. Anjos and Ferraz, 1999;Andrade et al, 2003;Daws et al, 2005;Mayrinck et al, 2016;Calvi et al, 2017a,b;Pelissari et al, 2018;Subbiah et al, 2019;Mattana et al, 2020). However, while seeds of some species are nondormant at maturity, others are dormant (e.g.…”

This review provides a revised and expanded word-formula system of whole-seed primary dormancy classification that integrates the scheme of Nikolaeva with that of Baskin and Baskin. Notable changes include the following. (1) The number of named tiers (layers) in the classification hierarchy is increased from three to seven. (2) Formulae are provided for the known kinds of dormancy. (3) Seven subclasses of class morphological dormancy are designated: ‘dust seeds’ of mycoheterotrophs, holoparasites and autotrophs; diaspores of palms; and seeds with cryptogeal germination are new to the system. (4) Level non-deep physiological dormancy (PD) has been divided into two sublevels, each containing three types, and Type 6 is new to the system. (5) Subclass epicotyl PD with two levels, each with three types, has been added to class PD. (6) Level deep (regular) PD is divided into two types. (7) The simple and complex levels of class morphophysiological dormancy (MPD) have been expanded to 12 subclasses, 24 levels and 16 types. (8) Level non-deep simple epicotyl MPD with four types is added to the system. (9) Level deep simple regular epicotyl MPD is divided into four types. (10) Level deep simple double MPD is divided into two types. (11) Seeds with a water-impermeable seed coat in which the embryo-haustorium grows after germination (Canna) has been added to the class combinational dormancy. The hierarchical division of primary seed dormancy into many distinct categories highlights its great diversity and complexity at the whole-seed level, which can be expressed most accurately by dormancy formulae.
