Simulated Low-gravity Environments and Respiratory Metabolism in Avena Seedlings.
Using horizontal and vertical axis clinostats and sand-grown oat seedlings (Avena sativa), it was found that horizontal clinostat rotation at 2 rpm increased respiration and inorganic and organic phosphorus content of seedlings. Increased coleoptile geotropism and root growth are attributed to rotational nullification of the directional component of the gravitational stimulus. These growth modi...
متن کاملRespiratory metabolism in mangrove seedlings.
The respiratory gaseous exchanges of detached whole mangrove seedlings (Avicennia, Bruguiera, Rhizophora) in a range of O(2) concentrations from 0 to 21% (air) were markedly reduced by the presence of external CO(2). Aerobic respiration decreased steadily for 16 days but the RQ remained at unity.In anoxia CO(2) output fell to half that in air. Ethanol accumulation was negligible but, relatively...
متن کاملRespiratory metabolism in buckwheat seedlings.
Young seedlings of buckwheat (Fagopyrum esculentum) respire in air with an RQ of unity. Analysis of respiratory substrates coupled with a study of the utilization of acetate-(14)C and glucose-(14)C suggest that both the Embden-Meyerhof-Parnas, tricarboxylic acid and pentose phosphate sequences participate in the total respiratory catabolism.In anoxia CO(2) dropped to one third of the aerobic ra...
متن کاملBiochemical and Antioxidant Responses of Borage Seedlings in Saline Environments
Background: Although borage ( Borago officinalis L.) is a valuable medicinal plant, no information is available on the responses of this plant to salinity. For this reason, it is necessary to determine responses of this plant to salinity . Objective: Since germination and early growth stage is one of the most critical phases of plant life under salinity condition this experiment was conducte...
متن کاملScaling the respiratory metabolism to phosphorus relationship in plant seedlings
There are empirical indications of an isometric scaling relationship between plants' respiratory metabolism rates and nitrogen contents. To test the hypothesis that there may be a similar relationship between plants' respiratory metabolism and phosphorus contents we used data obtained from 150 laboratory and field-grown seedlings representing 30 herbaceous species and 20 woody deciduous species...
