A laboratory experiment was carried out in the laboratories of (Seed Examination and Certification Department Ministry Agriculture Postgraduate Laboratories- College Agricultural Engineering Sciences - University Baghdad) 2021-2022, to determine best combination acadian concentration (seaweed extract) 0, 1500, 2000 2500 mg/L , under three levels salt stress 5, 10 15 dS/m as well control treatme...

The chemical composition of the essential oils of Melaleuca armillaris Sm., Melaleuca styphelioides Sm. and Melaleuca acuminata F. Muell., collected in Tunisia, was studied by means of GC and GC-MS analysis. In all, 46 compounds were identified, 38 for M. armillaris, 20 for M. acuminata and eight for M. styphelioides, respectively. The presence of a sesquiterpenic fraction (52.2%) characterized...

Endogenous electrical currents traverse embryos of a higher plant, the wild carrot Daucus carota L. Current enters the apical pole and leaves the region near the presumptive radicle in the radially symmetric globular embryo. Current also enters the exposed surfaces of incipient globular embryos. This electrical polarity precedes differentiation of vascular tissue and cotyledon development. Loca...

Salicylic acid has one of its characteristics the allelopathic potential. The present paper, is a research quantitative in nature aimed to assess potential salicylic identify best concentration range for other pure substances. bioassays were performed BOD incubator, seeking seedling growth by measuring radicle and hypocotyl length. Each bioassay occurred 12 days. concentrations used were: 1000,...

salinity and drought are two major abiotic stresses that affect rice (oryza sativa l.) production in worldwide. salt and drought tolerance and high seedling vigor of rice is one of the important traits in the establishment of seedling in direct planting system and saline and drought environments. in this research, the mapping population of f2:4 families derived from the cross between local vari...

Podophyllum hexandrum Royle is an important high-altitude plant of Himalayas with immense medicinal value. Earlier, it was reported that the cell wall hydrolases were up accumulated during radicle protrusion step of Podophyllum seed germination. In the present study, Podophyllum seed Germination protein interaction Network (PGN) was constructed by using the differentially accumulated protein (D...

Loosening of cell walls is an important developmental process in key stages of the plant life cycle, including seed germination, elongation growth, and fruit ripening. Here, we report direct in vivo evidence for hydroxyl radical ((*)OH)-mediated cell wall loosening during plant seed germination and seedling growth. We used electron paramagnetic resonance spectroscopy to show that (*)OH is gener...

Opoku, G., Vyn, T. J. and Voroney, R. P. 1997. Wheat straw placement effects on total phenolic compounds In soil and corn seedling growth. Can. J. Plant Sci. 77: 301-305. The effects of placement of wheat (Triricum aestivum L.) straw on the release of phenolic compounds potentially phytotoxic to corn (Zen mays L.) seedling growth were examined in plastic pots under controlled conditions in grow...
