Constraints on tree seedling establishment after fires: passing the germination bottlenecks
(2022-01-01)
Persistence and colonization by tree species in an environment following a fire depends on the effects on seed germination and seedling development. We used seeds of Kielmeyera coriacea and Qualea parviflora as a model to ...
Cryopreservation, early seedling development, and genetic stability of Oncidium flexuosum Sims
(2013-07-01)
An efficient cryopreservation protocol was developed for mature seeds of Oncidium flexuosum Sims. Seed morphology, protocorm formation, and early seedling development were also assessed. The effects of phloroglucinol and ...

What can cell cycle and ultrastructure tell us about desiccation tolerance in Leucaena leucocephala germinating seeds?
(2016-06-01)
Desiccation tolerance (DT) is the ability to tolerate dehydration to levels below 0.1 g(H2O) g−1(dry mass) and subsequent rehydration without lethal damage. Here, it is proposed that Leucaena leucocephala, a tree species, ...
SOWING PERFORMANCE BY A METERING MECHANISM OF CONTINUOUS FLOW IN DIFFERENT SLOPE CONDITIONS
(Soc Brasil Engenharia Agricola, 2016-09-01)
One of the reasons for the success of a productive culture is the correct sowing. Therefore, the seeds must be properly dosed, deposited and not damaged by the metering mechanism of the seed drill. So, the aim of this study ...
Seedling Development and Evaluation of Genetic Stability of Cryopreserved Dendrobium Hybrid Mature Seeds
(Humana Press Inc, 2014-03-01)
Vitrification, a simple, fast, and recommended cryopreservation method for orchid germplasm conservation, was evaluated for Dendrobium hybrid Dong Yai mature seeds. The genetic stability of regenerated seedlings was also ...
