Determination of the Physiological Maturity Point and Establishment of Physical Dormancy in Hymenaea martiana Seeds

Agronomy
In forest species with physical dormancy, defining the ideal harvest point is challenging because of the limited understanding of the relationships among maturation, physiological quality, and seed dormancy.

Remediation of Pb(II) and Cd(II) in Sea Water by Skeletonema costatum

Sustinere: Journal of Environment and Sustainability, 2017
The heavy metals that polluted sea water can end up polluting fish pond too. Hence, it is necessary to remove the heavy metals before sea water enters the fish pond.

The adsorption of Cd(II) and Pb(II) to chitin in seawater [PDF]

Journal of Colloid and Interface Science, 1990
The adsorption of Cd2+ and Pb2+ to the surface of chitin has been studied in seawater as a function of pH (2 to 8), temperature (5 to 60°C), salinity (4 to 36), and the presence of other transition metals. The rates of adsorption were quite rapid () and were affected by the presence of other metals such as Cu2+.

First Report of Viviparity in Seeds of the Physically Dormant Species Hymenaea martiana (Fabaceae)

Seeds
Viviparity is rarely reported in species with seed physical dormancy. This is because physical dormancy, common in tropical trees, results from the impermeability of the seed tegument to water and regulates the timing of germination.
