THERMAL STRESS IN THE ADEQUACY OF THE CHEMICAL SCARIFICATION PERIOD IN BRACHIARIA SEEDS

open access: yesRevista de Agricultura Neotropical, 2021
Forage seeds often have a low germination percentage due to their seeds' dormancy, such as seeds of the genus Urochloa. Chemical scarification is chosen to overcome the dormancy, yet the seed's vigor level is not taken into account.

Intraspecific Variation Along an Elevational Gradient Alters Seed Scarification Responses in the Polymorphic Tree Species Acacia koa

open access: yesFrontiers in Plant Science, 2021
Physical dormancy in seeds can challenge restoration efforts where scarification conditions for optimal germination and seedling vigor are unknown. For species that occur along wide environmental gradients, optimal scarification conditions may also ...

Natural regeneration potential and dynamics in boreal lichen woodlands of eastern Canada following soil scarification

open access: yesFrontiers in Forests and Global Change, 2023
Boreal lichen woodlands (LWs) are stable low tree-density zones of the Canadian boreal forest whose afforestation has been proposed as a way to create new C sinks and thus mitigate climate change.

Mechanism of endocarp-imposed constraints of germination of Lannea microcarpa seeds [PDF]

open access: yes, 2008
Lannea microcarpa, a multipurpose tree species from the dry African savanna, sheds seeds that often display inhibition of germination. The underlying mechanism was investigated using seeds processed from fully matured fruits collected from natural stands

Germination of Crotalaria and Lupinus (Fabaceae) seeds submitted to different pre-germination treatments and their effect on enzymatic activity during early germination

open access: yesBrazilian Journal of Biology, 2019
Most of the wild and native legume seeds has a hard and impermeable testa, which causes physical dormancy and prevents them from germinating even when environmental conditions are favorable.
