The production of high vigor seeds is essential for agriculture because it has an immediate positive impact on crop yields through proper plant establishment under ideal and stressful conditions. The desirable characteristics of a vigorous seed lot are its storage capacity in the dry state (longevity), high uniform germination and seedling establishment. Peanut plants produce flowers thro…
Due to global climate change, agricultural areas in the world are increasingly prone to climatic extremes. For most species, extreme temperatures and drought stress affects seed quality. This is particularly problematic in oilseeds, such as soybean and canola, and often results in what is known as the "green seed problem". This is when chlorophyll is retained in ripening seeds, resulting …
The re-induction of desiccation tolerance in germinated seeds is a strategy that allows us to study the mechanism associated with desiccation tolerance in seeds. Furthermore, this technique allows the identification of genes associated with drought during germination and seedling establishment. Drought is the main cause of the decline in world production of soybeans and responsible for an…
The retention of chlorophyll has affected the production of soybean in Brazil, mainly in the Cerrado biome. As a result, there has been a reduction in the quality of the lots, evidenced by a decline in germination and vigor, with losses in the establishment of appropriate plant population. Besides affecting the physiological quality of seeds, the presence of chlorophyll also has negative …
Dormancy can be characterized as an attribute that contributes to maintaining species survival after dispersal. However, from an agricultural point of view, it prevents rapid and uniform germination and causes delays during seed quality assessment. Peanut seeds experience dormancy soon after harvesting, which prevents rapid and uniform germination. Thus, the study of peanut seed germinati…
Soybean breeding programs have as main objectives to select superior genotypes by associating traits of agronomic interest, such as seed and oil quality. It is known that the "green seed problem" has brought serious damage to soybean agricultural areas in the world, particularly due to ongoing climate change. The elimination of this problem becomes increasingly necessary because soy is a …
Why do peanut seeds have reduced physiological quality? The hypothesis is that maturity disuniformity reduces the physiological quality of peanut seeds at harvest due to three main reasons: (I) part of the peanut seeds are immature at harvest, do not exhibit the complete acquisition of physiological quality and make up the seed lot, which reduces their performance; (II) the peanut seeds i…
Chlorophyll degradation is an important step during the maturation of soybean seeds, since its retention affects the physiological quality of the seeds and their related products. Abscisic acid (ABA) has a great contribution to the reduction of chlorophyll content in seeds and leaves. However, to find out whether ABA signaling / transduction is a key aspect for greening seeds, studies of …

In Brazil, peanut seeds often have low vigor and, as a result, they must be used in large quantities to ensure seedling establishment. Presently, this represents an expected loss of at least 30% of the seeds during the planting phase. In our PhD research we demonstrated that one of the main causes of this low vigor is an uneven maturation process. This causes a lack of seed uniformity, wh…
Soybean seeds with lower quality are more likely to occur in tropical conditions, leading to occurrence of reduced stand and low productivity. The production of seeds with high physiological quality is critical to the expansion of soybean in Brazil. However, advances in the quality of seeds are impeded by conflicting evidence about when the various features of physiological quality of so…
The chlorophyll retention has affected the production of soybean seeds in Brazil, mainly in the cerrado biome. As a result, has reduced the quality of lots, evidenced by decrease in germination and vigor, with losses in the establishment of appropriate population of plants at planting. Besides affecting the physiological quality of seeds, the presence of chlorophyll also exerts a negativ…
