Abstract:

The Ormosia hosiei is a secondary protected wild plant in China, and its seed has a hardness rate of 86%. To explore the characteristics of the hard seed and the difference in seed vigor between hard seeds and the non-hard seeds of O. hosiei, the water absorption characteristics, germination characteristics, seed coat structure, seed coat permeability, enzyme activity, and main biochemical substances of the O. hosiei seeds were determined. The results showed that the hard and dense seed coat is the main obstacle to absorbing water of O. hosiei seeds; the main reason is that the seed coat is co

Abstract:

Morphological characteristics of two types of Black cumin seeds (<em>Nigella</em> sativa), Indian and Ethiopian origin were subjected to examine in this study. Therein, two physical characteristics namely colour and appearance were investigated with a view of determining the possibility of the seed for decorticating. The whole seed, seed coat and cotyledon of Ethiopian origin <em>Nigella</em> seeds were examined using a Scanning Electron Microscope. Present study was also performed to determine the colour of both types of seeds “Indian and Ethiopian” before and after decortications

Abstract:

Selection for resistance to viviparous germination is an important step and one of the most effective strategies for solving the problem of vivipary in orthodox seed species. Vivipary generally occurs when mature fruits are exposed to rain. To understand the existing relationships between seed phenotypic characteristics, seasonal conditions and the prevalence of vivipary in <em>Lagenaria siceraria</em>, experiments were carried out under natural conditions during the short and long rainy seasons of 2014 and 2015. Three main conclusions were drawn from the results. Firstly, yellowish seeds

Abstract:

Plants do not produce the same amount of fruits and seeds every year. In this regard, one of the important issues is to collect seed stock for the coming years by calculating fruit and seed productivity of plants. Since the main indicator of seed quality is seed germination, the study of seed germination of introduced plants is of both theoretical and practical importance. The study of the period of seed viability preservation is also of great scientific and experimental importance.

Abstract:

Seed germination is a complex process involving imbibition, activation and subsequent growth. In addition to re-establishing metabolic activity, water uptake helps stabilize macromolecules and biochemical reactions, resulting in radicle protrusion. Factors affecting water uptake include seed composition, water availability and seed coat permeability. Water entry sites vary with species and occur primarily through the hilum, micropyle or lens. In addition, seed size influences water uptake, where larger seeds are usually less permeable. The seed coat plays a significant role in regulating the w

Abstract:

Kadsura coccinea (Lem.) A. C. Smith is a significant tree species of non-timber forest. However, the low germination percentage and lengthy germination time of its seeds pose obstacles to industry development. Aiming at the problem of seed dormancy, this study first determined the seed dormancy period through seed germination test, and then comprehensively evaluated the dormancy characteristics by observing the seed coat structure, measuring endogenous inhibitors, and in vitro embryo culture. The results indicated the dormancy of K. coccinea seeds, and that the germination period was up to 80

Abstract:

Vaccinium oldhamii Miq. is an edible berry; however, little is known about its seed dormancy-break and germination. Therefore, the aim of this study was to elucidate the seed-dormancy break and germination characteristics of V. oldhamii. The results showed that the length and width of the seeds of V. oldhamii were 2.4588 ± 0.0273 mm and 1.7028 ± 0.0248 mm, respectively, the filled percentage was 49.0 ± 3.0%, and the 1000-seed weight was 0.9453 g. Additionally, water imbibition test showed that the seed weight of V. oldhamii increased by more than 70% after 24 h, indicating the absence of physi

A range of experiments was conducted to evaluate the impact of abiotic factors on dogbane seed germination. Freshly harvested seeds were largely nondormant with viability ranging between 67 and 84%. Prolonged exposure to light neither promoted nor inhibited germination. Germination rates and total seed germination varied with temperature and osmotic potential. Significantly fewer seeds germinated at 5 C compared with 10, 15, and 20 C. There was a significant quadratic relations

Data showed that even after 10 years burial by 65–140 cm volcanic deposists, 16.6% of the seeds, representing 25 species, were viable. There were few predators in the former topsoil below the thick volcanic deposits. Seed volume of most species was less than 2.0 mm3 and smaller see

Abstract:

Brassica oleracea is an important crop species that at early growth stages may exhibit failure of the apical growing point, an abnormality called “blindness”. The occurrence of blindness is promoted by exposure to low temperatures during imbibition and germination, but the causes of sensitivity to such conditions are unknown. We combined three analytical seed technology instruments to explore seed physical properties that are highly correlated with quality parameters and might be used directly for grading or sorting seed lots into subpopulations varying in potential susceptibility to blindness

Germination can be enhanced from 2.3% (untreated) to over 75% either by nicking or by scarifying the seed-coat for 20-60 minutes using 95% concentrated sulphuric acid. For scarification 500 ml acid is required for a kg of seeds. Nicked and scarified seeds start germination from the fourth day and give a cumulative ge
