Abstract:
... Soil heavy metal pollution, especially lead (Pb) and arsenic (As), is a global issue that requires urgent attention. In the present study, phosphate-modified ferric-based material (PFM) was used to remedy Pb and As co-contaminated soil. The remediation potential of PFM on Pb and As co-contaminated soil was studied by static culture experiments, and the effect on maize (Zea mays L.) seedling growth ...

Abstract:
... There is a major need for restoration of nonforest ecosystems in the Brazilian Cerrado, and planting seedlings is promising. However, there is no currently available information on nontree species production in nurseries. Grasses are dominant in the Cerrado herbaceous layer; therefore, we tested whether tree seedling production techniques can be used for two native grasses widely spread across the ...

All the developmental and growth events in a plant’s life are connected to specific points in time, be it seed germination, seedling emergence, the appearance of the first leaf, heading, flowering, fruit ripening, wilting, or death. The onset of automated phenotyping methods has brought an explosion of ...

Abstract:
... Quinoa (Chenopodium quinoa Willd.) is a facultative halophyte which has taken great importance in recent years due to the nutritional characteristics of its seed. In environments with moderate to high salinity, both the decrease in water potential and the accumulation of Na⁺ and Cl⁻ ions can constitute stress factors that limit germination and seedling establishment. In the present study, we inves ...
