Elemental Composition and Implications on Brown Rice Flour Biofortified with Selenium.

Rice ( L.) is one of the most economically and socially important cereals in the world. Several strategies such as biofortification have been developed in a way eco-friendly and sustainable to enhance crop productivity.

Grain Composition and Quality in Portuguese Germplasm Subjected to Heat Stress after Anthesis.

Bread wheat () is a major crop worldwide, and it is highly susceptible to heat. In this work, grain production and composition were evaluated in Portuguese germplasm (landraces and commercial varieties), which was subjected to heat after anthesis (grain filling stage). Heat increased the test weight (TW) in Nabão, Grécia and Restauração, indicating an improved flour-yield potential.

Effect of Rice Grain ( L.) Enrichment with Selenium on Foliar Leaf Gas Exchanges and Accumulation of Nutrients.

An agronomic itinerary for Se biofortification of two rice cultivars (Ariete and Ceres) through foliar fertilization with sodium selenate and sodium selenite with different concentrations (25, 50, 75 and 100 g Se.ha), was implemented in experimental fields. The selenium toxicity threshold was not exceeded, as shown by the eco-physiological data obtained through leaf gas exchanges.

Quantification and Tissue Localization of Selenium in Rice ( L., Poaceae) Grains: A Perspective of Agronomic Biofortification.

In worldwide production, rice is the second-most-grown crop. It is considered a staple food for many populations and, if naturally enriched in Se, has a huge potential to reduce nutrient deficiencies in foodstuff for human consumption. This study aimed to develop an agronomic itinerary for Se biofortification of L.
