Changes in Level and Activity of Phospholipid Transfer Protein during Maturation and Germination of Maize Seeds.
The variations of the amounts of phospholipid transfer proteins (PLTP), determined by ELISA and immunoblotting methods, were followed during the maturation and germination of maize (Zea mays L.) seeds. Changes of the amounts of PLTP occur during seed maturation. The levels of PLTP, low in the first 3 weeks after fecondation, strongly raised 3 to 5 weeks after, then reached and maintained a high...
متن کاملImproving germination of Prunus avium L. seeds
To break dormancy and increase the germination of Prunus avium L. (mazzard cherry) seeds, various methods were tested including the removal of the seed coat after cold moist stratification and treatment with GA3, KNO3, or thiourea. Treatments with 7,500 ppm KNO3 after 120 days of stratification were more effective, yielding 64.54% germination of seeds with coat. In seeds without coat, 500 ppm G...
متن کاملAccumulation and degradation of thiamin-binding protein and level of thiamin in wheat seeds during seed maturation and germination.
Changes in the levels of thiamin-binding globulin and thiamin in wheat seeds during maturation and germination were studied. The thiamin-binding activity of the seed proteins increased with seed development after flowering. The thiamin content of the seeds also increased with development. Thiamin-binding activity decreased during seed germination. On the other hand, immunological analysis using...
متن کاملMaturation of Sweetgum and American Sycamore Seeds
Over three consecutive years in central Mississippi, sweetgum (Liquidambar styraci/lua L.) and sycamore (Platanus occidentalis L.) fruits had nearly reached fullsize by late June. Sweetgum seeds were physiologically mature by mid-August, but dry weight increased until late September. As sweetgum seeds matured, the crude fat level rose to 27 percent of seed dry weight. During maturation, concent...
متن کاملImportance of woody debris in seed germination of Tipularia discolor (Orchidaceae).
Concerns about declining populations of terrestrial orchids make it important to identify the environmental factors crucial to seedling recruitment. This study shows that seedlings of Tipularia discolor (cranefly orchid) primarily occur on decomposing wood. Extensive searches of decomposing logs and stumps in mature and successional forests revealed seedlings at 24 sites, of which 15 could be i...
