Special Issue Information

Dear Colleagues,

Most currently living vascular plant species reproduce in a generative way using seeds. Seed production, seed vitality, seed germination and seedling establishment are required for successful population growth and propagation. These trades are important for the study of wild plants because they reflect the ability of the species to develop in the landscape. Seed study is essential for conservation biology and species diversity.

The processes of germination and initial growth of seedlings are less known in wild plants than in purposefully grown species. However, the process of seed germination tends to be delayed in wild plants, and is often "complicated" by seed dormancy. In addition, natural environments are different from those in controlled laboratory conditions, natural habitats are coupled with multiple unpredictable abiotic and biotic factors. Ecological grasping of seed issues can therefore be problematic and much more complicated than with field crops.

Extreme weather conditions are generally expected to occur more often in the near future. This will cause impairment of plant growth in original areas of occurrence. The knowledge of seed biology will lead to understand reproduction via seeds and to improve planning for plant species management in conservation biology.

This Special Issue "Parameters of Seed Germination in Wild Plant Species" aims to stimulate discussion on seed germination and seedling early growth in individual plant species growing in the landscape habitats.

Despite exhibiting intriguing features associated with its multipurpose applications and drought tolerance, Ferula communis remains a wild and uncultivated species, with limited experimental research on its biology, starting from seed germination and extending to its ecology. The purpose of this study was to investigate potential germination and kinetics in F. communis seeds in response to four cold stratification periods (0, 15, 45, and 90 days at a constant temperature of 5 °C) and four temperatures (5, 10, 15, and 20 °C) under continuous darkness. F. communis exhibited a pronounced germination potential exceeding 90%, with the optimal temperature for germination falling within the range of 5 °C to 15 °C, without necessitating cold stratification. A dramatic drop of the germination percentage was observed at 20 °C (<10%), suggesting a form of conditional dormancy attributed to the higher temperature tested. Full article

Pinus oocarpa is the most important conifer for resin production in Mexico, so superior resin trees were selected in the Southern Mountains of Oaxaca, Mexico. The objective was to determine the variation and differences among provenances and among trees according to the parameters of seedling emergence and the number of cotyledons, and their relationship with elevation and climatic variables. The seedling emergence of four replicates of 20 seeds from 80 trees was counted daily. For the emergence parameters, provenance contributed 42.02% to the total variance, tree 29.19% and error 28.79%. Only tree (11.71%) and error (88.29%) contributed to the total variance of the cotyledon number. The effect of provenance (p ≤ 0.0006) and tree (p ≤ 0.0001) was significant for all variables evaluated. Higher-elevation provenances and trees had higher emergence values. The emergence parameters were positively associated with tree elevation. Climatic variables related to precipitation and temperature were negatively related to the emergence parameters. The results allow for the selection of phenotypes without emergence problems to establish seed orchards. Full article

The conservation of endemic plant species is a major concern, as the species are with restricted distribution range. Since in situ conservation alone will not guarantee their maintenance, ex situ conservation measures must be undertaken to support the conservation of these species. Investigation of the impact of the storage environment of seeds gives baseline information. Therefore, this study was conducted to investigate the effect of different storage conditions (room temperature, 4 °C and −10 °C) and different storage periods over one year. Four Ethiopian endemic plant species, namely Euryops pinifolius, Kniphofia foliosa, Lobelia rhynchopetalum, and Solanecio gigas, were considered. Multivariate analyses revealed a significant (p < 0.05) effect of storage condition and period on seed germination. The storage of seeds at room temperature before drying may not be recommended for short-term storage of the studied species, except K. foliosa. After drying of seeds, E. pinifolius, K. foliosa, and L. rhynchopetalum seeds showed high germination percentage (above 80%) after storage even at sub-zero temperatures for one year. The germination percentage of S. gigas stored at room temperature before drying for thirteen months was 60% and that stored at 4 °C was 6%, which indicates that the seeds may be categorized under intermediate storage behavior. The three species can be grouped in the orthodox seed storage category. Research on desiccation screening should be undertaken to predict an optimal combination of storage moisture content and suitable storage temperature to determine storage category with certainty.

The knowledge of the physiological aspects of Caatinga’s vegetal species is extremely important for preserving this biome, which suffers with human impacts, mainly to select propagation methods. Erythrina velutina is a Brazilian tree, generally found in Caatinga, with medical and forestry potential. The objective of this paper was to determine the best soaking period in gibberellin solution to achieve the highest germination and to evaluate the internal anatomy by digital microtomography of E. velutina seeds. The design was completely randomized and consisted of eight treatments: 1, 3, 6, 12, 24 and 48 h of soaking, scarified seeds and the control with no-scarified seeds. Digital microtomography was efficient in describing the anatomy of the seeds and distinguishing their tissues. There was no significant difference between the treatments at different soaking times, as the gibberellic acid did not influence the germination; only the control presented a lower germination percentage, differing from the other treatments. The study presents evidence that E. velutina seeds do not require the exogenous use of gibberellic acid, but only the scarification process. In addition, the use of digital microtomography can be useful in understanding the anatomy of seeds, especially forest species, which can contribute to the future studies of other plant species.
