Effect of Potassium Deficiency upon Translocation of C in Detached Blades of Sugarcane.

abstract：: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 reprodu...
