Effect of the interactions between moisture content, seed storage time and use of pesticides on seed germination, viability and viability indicators of wheat crop

Seeds of native forest species for food and seedling production have a growing demand that impacts the need for studies involving seed storage in order to maintain good levels of germination quality. Thus, scientific analyzes that explore the physiological potential of the seeds of these species are necessary, especially for the pink pepper (Schinus terebinthifolia Raddi.), a species used as an alternative source of income for traditional communities and which has been arousing interest due to the consumption of its fruits as a condiment in the national and international market. This work aimed to assess the physiological quality of pink pepper seeds according to the storage period and seed size. The seeds came from a rural settlement, a pioneer in the extraction of pink pepper, in the state of Rio de Janeiro, Brazil. The seeds were evaluated for moisture content, germination, first count, length and dry weight of the germinated seedlings, during the period of time that they remained stored and the size of the seeds. The results allowed to conclude that: i) the germinative percentage of the stored pink pepper seeds decreased over the months; ii) the moisture content of the seeds decreased over the months evaluated iii) the different sizes of seeds did not show differences in germination and storage time and iv) values of length and dry weight of the seedlings did not differ according to the period of storage.

Detailed study on seed storage and germination trailed in Knema attenuata (Wall. ex Hook. f. & Thomson) Warb.– the IUCN Red Listed ‘least concern’ medicinal tree species revealed that seeds were of recalcitrant nature. Viability of the seeds could be maintained for a longer period of up to 6 months with 47% Moisture content (mc) when kept in closed polycarbonate bottles at seed bank condition [20±20C Temp. and 40% Relative Humidity (RH)]. The 55% seed germination under normal climatic condition could be enhanced to a much higher percentage (75±5) inside the mist house chamber (34±30C Temp. and 70-80% RH).

The Adansonia (baobab) genus comprises seven species in Africa, six of which are endemic to Madagascar. Depending on the species, baobabs develop in widely varying ecosystems, including arid zones and savannahs, as well as dry and wet forests. Seeds from all species exhibited orthodox behaviour, tolerating dehydration to a moisture content of around 5%. There was no physical dormancy in the two species belonging to the Brevitubae section, A. grandidieri and A. suarezensis. Their seeds germinated without any prior scarification. The five other species, belonging to Adansonia and Longitubae section, have seeds with water-impermeable coats. In the case of A. digitata and A. za, the proportion of water-impermeable seeds was around two-thirds, whereas with A. rubrostipa, A. madagascariensis and A. perrieri, the proportion was >90%. Treatments allowing for the removal of physical dormancy needed to be markedly more severe with A. madagascariensis than with the other species. None the less, it seems impossible to link these characteristics and the interspecific differences to a strategy for adaptation by these species to their environment.

Background: Podostemaceae are extremely susceptible to local extinction by habitat loss. Since ~70 % of the river systems in Mexico show some degree of water contamination, it is relevant to generate information about seed storage and germination behavior to design germplasm conservation strategies (e.g., ex situ seed banks) of Mexican podostemads.Hypotheses: Seed germination decreases as seed storage time increases. Further, light quality, temperature and collection site influence similarly the germination response of both species.Studied species: Marathrum foeniculaceum Humb. & Bonpl., Noveloa coulteriana (Tul.) C. PhilbrickStudy site and years of study: 13 different seeds collections (1996-2013), at four locations in the rivers Horcones and Arroyo del Rincon Jalisco, México. Methods: A germination chamber experiment was performed to evaluate the effect of temperature, light quality and storage time on the germination of both species.Results: Seeds lose viability after nine years of storage. In both species, the time to reach the highest Accumulated Germination Percentage (AGP) was faster in seeds of one-two yr compared to seeds of six-seven yr. N. coulteriana have significant differences in Final Germination Percentage (FGP) between collection rivers. Storage time affects AGP of N. coulteriana more than in M. foeniculaceum.Conclusions: Both species can form ex situ seed banks up to 8 yr age in paper bags storage. N. coulteriana is more susceptible to variation in storage conditions compared to M. foeniculaceum. Collection site affect seed germination after storing. Long-term conventional ex situ seed germination storage is not a viable strategy to conserve germplasm of Podostemaceae.

Sunflower seed, cultivar Interstate 7111, was stored at 10, 20, 30, and 40 °C and 35, 45, 55, and 75% RH for up to 12 mo. At 75% RH fungal growth was extensive and free fatty acids (FFA) increased rapidly under all temperature regimes. Based on a threefold increase in FFA (1.5%) seed can be stored for 12 mo: at 6% moisture content (MC) and 30 °C; 7% MC and 20 °C; or 8% MC and 10 °C. Seed germination remained above 80% for 12 mo at 10 and 20 °C and 35, 45, and 55% RH; it declined to 70% at 30 °C and 45% RH, but at 55% RH it fell to 30% at 6 mo and 0% at 12 mo. Seed germination decreased rapidly at 40 °C. The incidence of microfloral infection by Penicillium spp. and Aspergillus spp. directly affected increased FFA, decreased germination, and infection was frequent at > 75% RH and different fungal species predominated at different temperatures. Eight species of stored-product beetles and one species of mite were placed on whole sunflower seed, ground seed, shells, or seed meat. Only Oryzaephilus surinamensis, O. mercator, Tribolium castaneum, and T. confusum multiplied appreciably in 2 mo, mainly on ground seed or seed meat. The Oryzaephilus spp. multiplied as much on sunflower seed as on ground wheat controls. Infestation of sunflower seeds by these pests is likely.

The purpose of the research study the viability and vigor of plants in the nursery and look for the optimum concentration of H2SO4 solution at each storage duration that gives the distance of the highest seed viability in the nursery. Experiments conductedin the seed laboratory and in the nursery Faculty of Agriculture Winaya Mukti University Tanjungsari using randomized block design (RBD) factorial, first factor the time and concentration of sulfuric acid solution: Soaking 6 minutes in H2SO4 0.25%, 0.50%, 0.75% and 1.0%. Factor II is a seed storage duration: without being stored, 1, 2, 3 months. Analysis of the data using linear quadratic regression method. The experimental results show that the interaction between seed storage time and concentration of sulfuric acid solution on seed germination, growth speed of seeds, and seed vigor. Without storage time and concentration of sulfuric acid solution 0.75% gives the best effect compared to other treatments. At the time of storage, followed without the optimum sulfuric acid concentration as much as 0.783% gives the percentage of seed germination was 93.521%.

Garcinia imberti seeds were collected during 2015-2017 from Shangili, Cheenikkala and Bonaccord evergreen forests of Agasthyamala Biosphere Reserve, the only abode of this endangered endemic species. Germinability of seeds were analysed through decoating, Gibberellic acid (GA3) and light inductive pre-treatments on fresh (62.8 % moisture content; MC) and desiccated (fast; 23.3% MC and slow; 30.5 % MC) seeds. The seed germination with impermeable coat (0.7-1.2 mm) was restricted which on decoating got enhanced. Application of GA3 along with exposure to light breaked dormancy within 4-6 days compared to non-treated seeds that took 238-254 days to germinate. Stored seeds behaviour revealed that seed moisture content and rate of germination were negatively correlated. Seed storage was found to be more efficient only up to 80 days at controlled seed banking conditions (20 ± 20C, 20 % relative humidity; RH). Both fast and slow desiccated seeds stored for 60 days in seed bank conditions exhibited 50.4 and 43.4 % of germination compared 39.4% germination of non-desiccated seeds. Hence fast desiccated and decoated G. imberti seeds pre-treated with GA3 on subsequent exposure to light alleviated dormancy. For seed banking, fast desiccated seeds with MC in between 40-20% are found to be promising.

Dry Storage

(H. LÃ©v.) Rehder is a rare, endangered, and therefore, protected tree species native to China. However, there are serious limitations to the effective protection of the species, including a low seed germination-rate and difficult storage due to a high seed oil-content. Here, we evaluated the feasibility of ultra-dry seed storage and its effects on seedling growth. We used the silica gel method to prepare ultra-dry seeds with different moisture contents to find an optimal moisture content range (2.54%â4.77%). Ultra-dry treatment improved storability of . Furthermore, seeds with a moisture content of 4.77% stored at room temperature, and seeds with a moisture content of 3.97% stored at 4 Â°C yielded the best results. Priming with an appropriate concentration of polyethylene glycol had a certain repairing effect on ultra-dry stored seeds and improved seed vigor, with a two-day priming treatment with 20% polyethylene glycol having the best effect. Finally, compared with sand storage at 4 Â°C, ultra-dry storage promoted seedling growth and root development; furthermore, it alleviated storage damage to seeds, promoted soluble sugar and soluble protein accumulation, and increased seedling nitrogen, phosphorus, and potassium uptake. Therefore, ultra-dry storage can be effectively used to preserve seeds. Specifically, low-temperature storage of ultra-dry seeds with a moisture content of 3.97% enhanced seed vigor, and seedling growth and development.Handeliodendron bodinieriH. bodinieri seedsH. bodinieriH. bodinieriH. bodinieri

The present research attempts to characterize the effect of low temperatures, and the moisture content of maize (Kosmo 230) meant for sowing on its energy and capacity to germinate. Seeds were moistened to varying degrees and stored under various conditions; then, their germination energy and capacity were assessed. Sowing material with 15% moisture content showed slightly declined germination ability when stored at −25–−20 °C for over three days, while the storage of seeds with a 25 and 30% moisture content at −5–0 °C for 1–3 days had the effect of seed conditioning. Seedlings obtained from conditioned seeds showed sustainability characterized by faster growth, and demonstrated nearly twice the size as other plants. Warehousing and storage of maize grains with a 11.12% moisture content at temperatures up to −25 °C did not significantly affect seed germination capacity or energy, irrespective of storage time.
