The Mechanism of Abscisic Acid-induced Proline Accumulation in Barley Leaves
AUTOR(ES)
Stewart, Cecil R.
RESUMO
When leaf blades of fully expanded second leaves of barley (cv. Prior) were excised and incubated with the cut end in a 20 milligram per liter solution of abscisic acid, they accumulated proline at the rate of about 1 micromole per hour per gram fresh weight after a 3- to 4-hour lag. This accumulation occurred reproducibly only if leaves were pretreated by placing the cut end in a solution consisting of 50 millimolar sucrose and 1 millimolar glutamate. Treated leaves were taken from plants which had been in the light for 24 hours.
