Seeds generally consist of 3 parts: Cotyledons or embryonic leaves, the embryo from which growth commences, and the outer protective covering called the seed coat. However, the structure of seeds and their parts differ in dicot and monocot. Structure of monocotyledonous seed Seed coat:The seed ...
2020). The seeds ofB. napusare mainly composed of two parts, embryo and seed coat [1]. Though oil and protein are concentrated in the embryo, seed coat plays crucial roles in many biological processes such as signal transmission, nutrition transportation...
Regardless of the fat content, most legume seeds have a similar structure. Mature legume seeds have three major components: the seed coat, the cotyledons, and the embryo axis. In most dry seeds, they account for 8–20, 80–90, and 1–2% of the seed weight, respectively. The majority ...

Results The germination rate of embryo in peach The germination rate of 'Yaguchi' after rinsing for 7 days was significantly higher than that after rinsing for 2 days when the chilling period was 4 weeks (Fig. 1). Chilling periods of between 6 and 8 weeks promoted seed dormancy breaking ...
and the expressions of inflammatory factors IL-6, TNF-a, iNOS and COX-2 were decreased in HaCaT cells. From the gene level, the mRNA contents of IL-6, TNF-a, Caspase-3, Caspase-9, Bax and Bcl were significantly decreased. The test of chick embryo chorioallantoic membrane (HTET CAM) ...
This structure serves the dual function of bearing the archegonia and of nourishing the young embryo. Food accumu- lation is a prezygotic phenomenon that affects fertile as well as sterile prothalli, and is therefore indepen- dent of fertilization (Maheshwari & Sing, 1967). Too much ...
Seed development can be divided into endosperm development, cell division, embryo and cotyledon differentiation, embryo development, seed dehydration and carbohydrate accumulation [31]. In general, the cell differentiation of soybean seed is completed at 20 DAF to 25 DAF. At this stage, the cells ...
Drought stress affects germination through creating low osmotic potential preventing water uptake by the seed, affecting the movement and transfer of seed resources, or directly impacting the organic structure and protein synthesis in the embryo. If water uptake by the seed is impaired, the metabolic...
