Phytic acid mobilization is an early response to chilling of the embryonic axes from dormant oilseed of hazel (Corylus avellana).
Dormancy of hazel (Corylus avellana L.) seeds is alleviated by a chilling treatment during which cytological, hormonal, and biochemical changes occur. Phytic acid and phosphate mobilization have been examined during this treatment. Phytic acid accounted for 0.7% and up to 3.2% of dry weight in axiferous and cotyledonary tissue, respectively. Phytic acid levels in embryonic axes were reduced by ...

متن کاملSomatic Embryogenesis and Plant Regeneration from Embryonic Axes and Cotyledons Explants of Tea (Camellia sinenesis L.)
In the present study, 2, 4-dichlorophenoxyacetic acid (2, 4-D) was assessed individually for its effectiveness to induce somatic embryogenesis in tea (Camellia sinenesis L.). Embryonic axes and cotyledons explants were dissected from the seeds. Explants were cultured on Murashige and Skoog (MS) medium containing 0, 1 and 5 mM 2, 4-D alone for embryonic axes and 0, 1 and 5 mM 2, 4-D along with 0...
متن کاملAdenylate metabolism of embryonic axes from deteriorated soybean seeds.
RNA and protein syntheses in axes excised from dry soybean (Glycine max L.) seeds at different levels of deterioration were assayed. Low rates of protein synthesis in slightly deteriorated seeds were not due to losses in ribosomal or soluble fraction activities. However, the lowered rates of RNA and protein syntheses of deteriorated seeds were associated with reduced ATP content of the tissues....
