Cantharis 200c counters heat stress in germinating seeds of Vigna unguiculata (L) Walp

Int. j. high dilution res; 17 (3/4), 2018
Background Thermal stress during early imbibitional phase of germination causes disruption of redox-homeostasis by increasing accumulation of ROS Reactive Oxygen species (assessed in terms of hydrogen peroxide) and significant reduction of antioxidative defense (assessed in terms of catalase and peroxida...

Physiological, cellular and molecular aspects of the desiccation tolerance in Anadenanthera colubrina seeds during germination

Braz. j. biol; 77 (4), 2017
Abstract During germination, orthodox seeds become gradually intolerant to desiccation, and for this reason, they are a good model for recalcitrance studies. In the present work, physiological, biochemical, and ultrastructural aspects of the desiccation tolerance were characterized during the germination...

Carbon and nutrient stocks of three Fabaceae trees used for forest restoration and subjected to fertilization in Amazonia

An. acad. bras. ciênc; 89 (3), 2017
ABSTRACT Amazonia is crucial to global carbon cycle. Deforestation continues to be one of the main causes of the release of C into the atmosphere, but forest restoration plantations can reverse this scenario. However, there is still diffuse information about the C and nutrient stocks in the vegetation bi...
