Aging cylinders excised from ;Golden Delicious' apple (Pyrus malus L.) pulp, like the intact fruit, exhibit some characteristic phenomena such as rise in respiration (climacteric), ethylene synthesis, enzymic changes, and increase in ribosomes and mRNA. Aging of cylinders of pulp tissues may offer a useful physiological tool for the study of maturation and senescence.

Scirtothrips dorsalis Hood (Thysanoptera: Thripidae) is an insect of Asian origin and currently distributed in several countries around the world. It has highly polyphagous habits been reported as a primary pest different fruit, horticultural, ornamental crops. This species was Mexico 2020, however, due to its invasive nature rapid adaptation new ecosystems, it probably present other regions co...

Plastid genomes exhibit different levels of variability in their sequences, depending on the respective kinds of genomic regions. Genes are usually more conserved while noncoding introns and spacers evolve at a faster pace. While a set of about thirty maximum variable noncoding genomic regions has been suggested to provide universally promising phylogenetic markers throughout angiosperms, appli...

The flowers of Hyaloseris salicifolia afforded known ivasperin, while the leaves afforded ivasperin and 2-O-(6'-O-acetyl-beta-D-glucopyranosyl)-ivasperin, whose structure was determined by spectroscopic methods.

d'Anjou cv. pear fruit (Pyrus communis L.) exposed at harvest to 0, 0.42, 4.2, or 42 micromol m(-)(3) 1-methylcyclopropene (1-MCP) for 12 h at 20 degrees C were stored at 1 degrees C for up to 8 months. After storage, half of the fruit was continuously exposed to ethylene (0.45 or 4-18 mmol m(-)(3)) for 7 days at 20 degrees C. All fruit treated with 1-MCP had lower respiration and ethylene prod...
