Voorbeelden van ethylene

  • Again, if, by addition to an unsaturated compound like ethylene, a saturated compound is formed, the kind of union between the carbon atoms is changed, and the possibility of revolution of the two parts of the compound is given. 

  • Thus, suppose that chlorine is added to ethylene. 

  • Non-dormant seeds were at least 50-fold more sensitive to ethylene than the dormant ones.

  • The data available on zygotic embryogenesis suggest an association of the ethylene biosynthetic pathway and seed maturation.

  • The thickness of the silique, an organ that does not produce ethylene, may have a key role in controlling the gas concentration during maturation.

  • The majority, if not all, of the species evaluated have seeds that produce ethylene prior to, or concomitant with, radicle protrusion.

  • A brass plate formed the roof of the container and was cooled by pumping a mixture of ethylene glycol and water through its interior.

  • It is, therefore, tempting to ascribe more rapid completion of germination to an ethyleneinsensitive testa developing in an ethylene-insensitive environment.

  • Several steps are potentially mutagenic, such as exposure to high cytosolic concentrations of ethylene glycol, and the extreme dehydration that is a requisite for vitrification.

  • This may result in the localized build-up of seedling-produced contaminants, such as ethylene, or changes in metabolic gas levels.

  • Both amino acids contribute the carbon atoms for ethylene formation.

  • This type of phosphorelay signalling, which is likely to function via histidine protein kinases, involves signal receptors for ethylene, cytokinins, light and osmolarity.

  • This demonstrates that the endocarp is permeable to ethylene and does not interfere with ethylene production by the seed.

  • In addition, there is direct evidence that ethylene is important for normal seed development in tobacco.

  • Differences in post-thawing survival between ovine morulae and blastocysts cryopreserved with ethylene glycol or glycerol.

  • In the postgerminative period the activity of the last step of ethylene biosynthesis decreased.

  • The relationship between ethylene and increased osmotic potential is not well understood.
