Synergy of Selenium and Silicon to Mitigate Abiotic Stresses: a Review.

It is evident the increase in the occurrence of different stresses that impact agriculture and so there has been an increase in research to study stress mitigators including silicon (Si) and selenium (Se). However, the great challenge to be answered would be to assess whether it is possible to maximize these benefits by combining these two elements. Therefore, this review focused on discussing the feasibility of combining Se and Si in mitigating abiotic stresses and also measuring gains in yield and quality of agricultural products.

Selenium increases photosynthetic capacity, daidzein biosynthesis, nodulation and yield of peanuts plants (Arachis hypogaea L.).

This study aimed to investigate the roles of selenium (Se) application on the profile of photosynthetic pigments, oxidant metabolism, flavonoids biosynthesis, nodulation, and its relation to agronomic traits of peanut plants. Two independent experiments were carried out: one conducted in soil and the other in a nutrient solution. When the plants reached the V2 growth stage, five Se doses (0, 7.

Can 2,4-D promote the hormesis effect in upland rice?

This study aimed to evaluate the influence of low doses of 2,4-D on the agronomic traits of upland rice applied at different stages of crop growth. The work was carried out in a randomized completly blocks, and consisted of the application of 5 low doses of the 2,4-D herbicide (0, 0.68, 1.

Does the glufosinate-ammonium herbicide have the potential to induce the hormesis effect in upland rice?

This study aimed to evaluate the effects of low doses of the herbicide glufosinate-ammonium in different application modes in the vegetative development of upland rice. The treatment consisted of a combination of five low doses (0; 15; 30; 60; and 100 g a.i.

Can the application of low doses of paraquat induce the hormesis effect in upland rice?

This study aimed to verify the effects of the application of paraquat low doses on the agronomic traits of upland rice in two different application modes. The treatments consisted of a combination of 6 low doses of the paraquat (0; 20; 40; 60; 80 and 120 g a.i.

Can the application of low doses of glyphosate induce the hormesis effect in upland rice?

The aim of this research was to verify the effect of glyphosate low doses on leaf macronutrient levels and vegetative traits of upland rice in two growth stages. The treatments were arranged in 2 × 6 factorial scheme. The first factor consisted of applications in two growth stages of rice crop (tillering and floral differentiation) and the second factor was the low doses of glyphosate (0, 10, 20, 40, 70 and 100 g e.
