We present the procedure to assemble a seed coat bedding assay (SCBA) from Arabidopsis thaliana seeds. The SCBA was shown to be a powerful tool to explore genetically and in vitro how the endosperm controls seed germination in dormant seeds and in response to light cues. The SCBA is in principle applicable under any situation where the endosperm is suspected to influence embryonic growth.

Here, we present a protocol to optimize asymbiotic seed germination, seedling development, and shoot elongation in Hemipilia cucullata. The protocol also enables the induction of protocorm-like bodies from sterile leaf explants, facilitating efficient in vitro propagation for the conservation and sustainable use of this endangered medicinal orchid.

2026
This protocol combines standardized seed surface sterilization with controlled germination to enable the reproducible isolation of tomato seed-associated microbiota during the seed-to-seedling transition. The approach enhances recovery of culturable microorganisms that are underrepresented in dry seeds and supports comparative culturomic studies during early seedling development.

Seed Structure and Early Development of the Sporophyte

2020
Seed structures are composed of a protective seed coat surrounding a plant embryo, and a food store for the developing embryo. The embryo contains the precursor tissues for leaves, stem, and roots. The endosperm and cotyledons—seed leaves—act as the food reserves for the growing embryo. The embryo contains a double set of chromosomes, one set from each parent. Fertilization of the haploid egg by the haploid sperm gives rise to the zygote, which develops into the embryo. The endosperm is a...
FAQs
Imbibition supplies the initial physical change that reactivates a seed’s internal processes. Water enters seed tissues, causing them to swell and supporting the return of metabolism. That renewed activity allows stored nutrients to become available to the embryo, linking water uptake to the later appearance of cell division, elongation, and radicle emergence.
These conditions represent the environmental requirements surrounding the transition to active growth. Moisture initiates physical and metabolic changes, while oxygen and temperature are also identified as necessary parts of a suitable environment. Considering all three helps researchers relate germination outcomes to environmental conditions rather than treating seed development as an entirely internal process.
After metabolism resumes, stored nutrients are mobilized to support the embryo’s renewed development. Their use accompanies cell division and elongation, allowing growth to proceed before the emerging plant is established. This relationship makes nutrient mobilization an important biological link between the end of dormancy and the seedling’s first visible developmental changes.
A basic study provides suitable moisture, oxygen, and temperature, then follows the seed for evidence of renewed growth. The most notable early observation is emergence of the embryonic radicle, which appears before the other described growth changes. Recording this event connects environmental conditions with the transition from dormancy to active plant development.
Germination studies support seed testing by showing whether seeds can begin active growth under suitable conditions. They also inform propagation methods and efforts to improve crop establishment. Because researchers can connect environmental requirements with early development, these studies provide practical information for evaluating seed performance and supporting more reliable plant production.
Germination research reveals how early plant establishment relates to environmental conditions, including moisture, oxygen, and temperature. That information can support the selection of varieties suited to changing climates. In biology and agriculture, the focus on early radicle emergence and renewed growth helps connect environmental responses with successful reproduction and crop establishment.
