Comparative study of the morpho-physical characteristics of two varieties of seeds of Sphenostylis stenocarpa and the evaluation of the nutritional potential of seeds and tubers revealed significant differences in seed density and color. Black seeds are less bulky and denser (1.5 g/mm3) than brown seeds (1.2 g/mm3). Seeds are richer in protein (23% and 27%) and fat (2%) than tubers (8-10 and 0....

A GC-MS method was performed to determine the total delta9-THC content in both drug- and fiber-type cannabis seeds. Drug-type seeds were found to contain much higher levels of delta9-THC (35.6-124 microg/g) than fiber (hemp) seeds (0-12 microg/g). The majority of delta9-THC was found to be located on the surface of the seeds. Approximately 90% of the total delta9-THC was removed by a simple, qu...

Dormancy breaking and germination requirements were investigated in seeds of Ferula ovina and Ferula gummosa. Seeds of rather species were collected from north and eastern-north rangelands of Iran. Seeds of each of the species were subjected to different treatments including various levels of GA3, chilling and combination of GA3 and chilling (GA-chilling). In contrast to treated seeds, non-trea...

†Background and Aims Mimetic seeds simulate the appearance of fleshy fruits and arilled seeds without producing nutritive tissues as a reward for seed dispersers. In this strategy of seed dispersal, seeds may remain attached to the mother plant for long periods after maturity, increasing their availability to naı̈ve seed dispersers. The hypothesis that seed coat impermeability in many tropical F...

Purpose In retinoblastoma, adjuvant chemotherapy after enucleation is given in eyes with histopathological high-risk features (HRFs) to reduced mortality. Anterior chamber seeds (AC seeds) on histopathological evaluation are a contentious finding. This study attempts to determine the effect of AC seeds on the survival rate. Methods This is a retrospective case record review. Eyes were divided...

Incubation of lettuce seeds (Lactuca sativa L. cv. Grand Rapids) in 0.3 m mannitol allows sufficient water uptake to make seeds fully sensitive to red light. But germination is possible only after lowering the osmotic potential of the incubation medium. The red light induction of these incompletely hydrated seeds can be reversed by far red light. Their reversibility declines with time at a slow...

using nigella sativa l. (black cumin), in traditional medicine, dates back to tutankhamen, the pharaoh of egypt. there are aboundant historical and religious evidence implying the importance of these curative seeds. traditionally, they have been used for various therapeutic purposes. zokam and nazleh (zan) are two nasal diseases used to be treated by these medicinal seeds. traditional persian m...

Transition seeds exhibit a good tradeoff between sensitivity and specificity for homology search in both coding and non-coding regions. However, identifying good transition seeds is intractable. This work studies the hit probability of high-order seed patterns. Based on our theoretical results, we propose an efficient method for ranking transition seeds for seed design and list good seeds in di...
