The use of hypobaric pressures has increased the precision of abscission research by enabling us to differentiate between abscission action of ethylene and abscisic acid. When cycloheximide is sprayed on fruit attached to trees, enhanced levels of ethylene occur in the fruit and, subsequently, the fruit abscises. When ethylene in the ...

Gibberellic acid-induced ?-amylase synthesis in wheat aleurone layers (Triticum aestivum L. var Potam S-70) escaped from transcriptional control 30 h after addition of the hormone, as evidenced by the tissue's loss of susceptibility to cordycepin. Abscisic acid inhibited the accumulation of ?-amylase activity when added to the tissue ...
