Objective: Exploring seed storage method to offer a technological support for the seedling development of Bletilla striata.
Methods: Bletilla striata seeds were stored by means of sand storage, nature storage and low temperature storage for 120, 150 and 180 d respectively. The germination rates were measured with methods of seed germination on the Petri dish and difference of rates was compared by means of the SSR method.
Results: The embryo rate of Bletilla striata seeds was (84.9 +/- 4.7)%; the germination rate of fresh seeds was (92.1 +/- 2.1)%; the germination rates of seeds treated by sand storage, nature storage and low temperature storage for 120, 150 and 180 d were (89.3 +/- 2.7)%, (77.4 +/- 3.3)%, (68.9 +/- 2.7)% respectively and they showed significant difference or extreme significant difference one another. When seeds stored 120, 150 and 180 d, germination rates of seeds treated with three methods were (81.7 +/- 8.0)%, (78.5 +/- 7.9)%, (75.7 +/- 8.5)% respectively, and in these three storage times, germination rates of seeds stored 120 d and 180 d showed significant difference. In addition, there was no significant difference between germination rates of fresh seeds and sand storage seeds stored 120 d.
Conclusion: The effect of germination of seeds stored with sand was good, and germination rate was high steal after 180 d.

Ex situ conservation of plant genetic resources (PGR) plays a crucial role in sustainable growth and development, as highlighted by the Global Strategy for Plant Conservation (GSPC). Seed genebanks, a key component of ex situ conservation, have been instrumental in preserving plant diversity. However, challenges arise with the conservation of non-orthodox (recalcitrant and intermediate) seeds and vegetative tissues, which are not amenable to storage in traditional genebanks at temperatures of -20°C.

Background: Sycamore tree-derived hypoglycin A (HGA) toxin causes atypical myopathy (AM), an acute, equine pasture-associated rhabdomyolysis but incidence fluctuates.
Objectives: Investigate whether tree or environmental factors influence HGA concentration in sycamore material and are associated with AM relative risk.
Study Design: Retrospective and experimental prospective study.

A purple-pigmented (purple) rice seeds containing an anthocyanin, a major class of flavonoids, and their isogenic non-pigmented (white) seeds were exposed outside of the international space station (ISS) to evaluate the impact of anthocyanin on seed viability in space. The rice seeds were placed in sample plates at the exposed facility of ISS for 440 days, with the bottom layer seeds exposed to space radiation and the top layer seeds exposed to both solar light and space radiation. Though the seed weight of both purple and white seeds decreased after exposure to outer space, growth percentages after germination of purple and white seeds in the top layer were 55 and 15 %, respectively, compared to those in the bottom layer 100 and 70 %, respectively.

Salt stress inhibits rice seed germination. Strigolactone (GR24) plays a vital role in enhancing plant tolerance against salt stress. However, GR24's impact on the metabolism of stored substances and endogenous hormones remains unclear.

Unlabelled: Seed storability is a crucial agronomic trait and indispensable for the safe storage of rice seeds and grains. Nevertheless, the metabolite mechanisms governing rice seed storability under natural conditions are still poorly understood.
Methods: Therefore, the seed storage tolerance of global rice core germplasms stored for two years under natural aging conditions were identified, and two extreme groups with different seed storabilities from the rice group were analyzed using the UPLC-MS/MS metabolomic strategy.
