“…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.

“…During storage, soybean seeds undergo metabolic processes that can lead to deterioration. The consumption of seed reserves, such as sugars, proteins, and oils, diminishes germination rates and seed vigor, directly impacting the successful establishment of the crop (Mahjabin et al, 2015;Meneguzzo et al, 2021). These metabolic reactions are boosted under field conditions, such as heat, drought, and other environmental factors that reduce seed quality, viability, and vigor (Rao et al, 2023).…”

The soybean (Glycine max (L.) Merrill) sowing in dry soil occurs under high temperature and low soil moisture conditions, which can impair seed vigor and emergence. The aim of this study was to evaluate the effects of dry soil storage on the soybean seed physiological quality of soybean seeds and the performance of high-vigor cultivars under these conditions. For this, a 3 × 3 factorial was applied, consisting of three soybean cultivars and three dry soil storage times (14, 7, and 0 days), in a completely randomized design, with four replicates. The evaluated traits were: emergence at 7 days, emergence at 14 days, radicle length, epicotyl length, and seedling dry mass. The data were subjected to analysis of variance, Scott-Knott mean grouping, and Pearson linear correlation. The cultivar × dry soil storage time interaction was significant for all traits, which allowed the evaluation of cultivar performance for higher seed physiological quality. The cultivar NA 5909 RG showed higher seedling emergence at 7 days (57%) when subjected to 14 days of sowing in dry soil (DSS), while the cultivar BMX Delta was superior at 0 DSS. Seed physiological quality was statistically similar at 0 and 7 DSS, and lower at 14 DSS. The genetic variability obtained between cultivars allows specific recommendation of cultivars for different water availability conditions and storage periods in dry soil. The cultivar NA 5909 RG is recommended for sowing in dry soil with up to 14 days of no rain, while the cultivar BMX Delta has higher vigor under readily available water.
