Skinner and Shive-lettuce Seed Germination3

germinated within 24 hours after prior exposure either to blue light or when maintained under complete darkness. However, far-red light augmented the germination of seeds pretreated with 6-benzylaminopurine so that nearly all such seeds germinated within 24 hours after treatment (table II). Far-red light also augmented the rate of germination of seed pretreated with a synergistic mixture of 6-b...

Epilepsy and chromosomal abnormalities

BACKGROUND Many chromosomal abnormalities are associated with Central Nervous System (CNS) malformations and other neurological alterations, among which seizures and epilepsy. Some of these show a peculiar epileptic and EEG pattern. We describe some epileptic syndromes frequently reported in chromosomal disorders. METHODS Detailed clinical assessment, electrophysiological studies, survey of t...
