Photoacoustic detection of C2H4 emission from germinating striga seeds

Photoacoustic detection of C2H4 emission from germinating striga seeds

An acetaldehyde dehydrogenase from germinating seeds.

An acetaldehyde dehydrogenase from germinating peanut cotyledons has been purified and its properties have been studied. At the highest purification achieved the preparation is free of alcohol dehydrogenase activity.The enzyme is specific toward diphosphopyridine nucleotide, and can oxidize a variety of aldehydes. The highest reaction rate is obtained with acetaldehyde, which is oxidized to ace...

Photoacoustic Measurements of Agriculturally Interesting Gases and Detection of C2H4 below the PPB Level

Amino Acid composition of germinating cotton seeds.

Total and free amino acid composition of germinating cotton seeds (Gossypium hirsutum L.) was determined. The germinating seeds were separated into cotyledon and developing axis fractions daily and the composition of each tissue was summed to get the whole seed composition. By separating the developing seeds into these two tissue fractions, and determining total and free amino acids, a balance ...

Phosphorus metabolism of germinating oat seeds.

An investigation has been made of the changes in the major phosphorus containing substances in Avena sativa during the first 8 days of dark germination. The endosperm, roots, and shoots were analyzed separately for acid soluble-P, phytic acid-P, inorganic-P, lipid-P, nucleic acid-P, and protein-P. Phytic acid-P comprised 53% of the total seed phosphate, while the sum of lipid-P, nucleic acid-P ...
