“…Differences in seed vigor can lead to the formation of seedlings with greater unevenness, due to the reduced capacity to use the reserves present in the embryo's structures, in fact affecting the growth rate and dry mass production, due to the inequality in the issue of growth of the plant between the different vigor levels (Meneguzzo et al, 2021). Only one of the 14 seed lots presented a significant response in the percentage of normal seedlings to KNO 3 (Table 2); these seeds probably had low vigor due to the storage time.…”

Prolonged storage of seeds may lead to decreases in seed quality, negatively affecting germination and vigor and preventing the obtaining of a promising stand. Seed quality is a critical factor, and the performance of the lot can be altered by vigor, dormancy and, mainly, by the time and conditions in which the seeds were stored. In the experiment, the physiological quality of seeds 14 genotypes of buffel grass (Cenchrus ciliaris L.) genotypes stored for a period of thirteen years in cold conditions was evaluated. The seeds were subjected to germination induction treatment with potassium nitrate (KNO3) and evaluated to identify seeds with presence and absence of embryos. The seed storage period affected their germination capacity and the use of KNO3 did not increase seed germination. A low number of full seeds was found for genotype 613 (12%). The relative germination percentages did not underestimate the buffel grass seed germination potential, as it is usually calculated, providing an improved distinction between the evaluated genotypes. The use of KNO3 increased the seedling root and shoot weights of some genotypes, as well as the dry matter weight of seedlings, an important characteristic for forage production. The prolonged storage affects the physiological quality of buffel grass seeds. The production of seeds without embryo is a problem found for this species, which affects the final quality of the seed lots produced.

“…Many studies identified moisture retention capacity of seeds, germination rates, uniformity and growth as the main components of seed vigour, that are also negatively influenced by seed storage conditions ( Egli et al., 1990 ; Finch-Savage and Bassel, 2016 ; Ebone et al., 2020 ; Meneguzzo et al., 2021 ). These components are said to play a key role in germination and seedling development.…”

The physical and physiological roles of seed properties are often neglected during plant tissue culture. These properties determine the level of activity and performance of seeds, which is commonly known as seed vigour. This paper reports on the role of seed vigour on seed germination and shoot induction using cotyledonary node explants. For this, explants prepared from soybean seedlings established using seeds stored under ambient conditions for different durations (0, 3, 6 and 9-months) were used. The findings indicated that seed germination was highly instantaneous after harvest and began to decrease as seed storage was prolonged for 3, 6 and 9-months, respectively. Similar observations were made during shoot induction. Generally, the analysis revealed a positive relationship between seed vigour, germination and multiple shoot initiation as indicated by the Pearson's correlation coefficient reported. According to the findings, seed vigour could serve as a major obstacle to efficient germination and shoot proliferation for subsequent in vitro plant regeneration.

A detailed structural investigation of a promising bio-based polymer, polyglycerol citrate polyester, obtained by the bulk polycondensation of glycerol (Gly) against citric acid (Cit) under mild reaction was performed. The reaction in conditions with and without catalyst use (sulfuric acid, H2SO4) was investigated, showing evidence that it is possible to modify the polymer solubility according to the ratio and catalyst utilization. 13C and 1H NMR indicated that synthesis catalyzed with Cit excess leads to higher esterification degrees of citrate groups. In contrast, the Gly moieties are more prominent in catalyzed polymers regardless of the excess monomers. Overall, a successful conversion of Gly and Cit into polyesters was attained even without catalysis, enabling a simple route for the large-scale production of this green material to be used as a coating material. This polymer has been shown to be well-suited for coating seeds and might be a promising material for similar agricultural applications. Tests on soybean seed coating with a PGCit solution of 75% indicated that the seed quality and germination rate were not affected by the PGCit coating, concluding that this polymer is suitable for this application.
