OHLSSON [1926; 1930] concluded from experiments on the action of the "dextrinogenamylase" and "saccharogenamylase" of malt on starch that the former enzyme breaks starch into progressively smaller molecules until maltose is produced, whereas the latter enzyme detaches maltose molecules successively from the starch. This conclusion was based mainly on the relative permanence of the starch-iodine...

A study was carried out over a two year period (2009/2010 and 2012/2013) on an experimental farm in the Alentejo region (Beja), in southern Portugal where rainfed malt barley (Hordeum distichum L.) is sown at the end of autumn or beginning of winter (November–December). The aim of this experiment was to study the efficiency of the herbicide iodosulfuron-methyl-sodium to control post-emergence b...
