Growth of spring barley stands was followed in various conditions. Disposition of the seeds parameters the morphogenetic programme of each individual plant, which will atterwards form the structure of the young plant stand. Later, individual stopping of tillering is controlled by this structure. In
Pyruvate kinase (ATP: pyruvate phosphotransferase, EC 2.7.1.40) is a key glycolytic enzyme that catalyzes the formation of pyruvate and ATP from phoshoenolpyruvate and ADP. The enzyme from several non-plant sources has been purified and studied extensively [8,9,12,15,18]. Most of these enzymes are h
As found earlier, supply of EDTA was obligatory for both flowering and satisfactory vegetative growth in Wolffia microscopica. It is now shown that the metal affecting growth and flowering is most probably iron. Omission of Fe but not of Cu, Zn, Mn and B from the medium markedly affects vegetative g
From a study of differently aged populations of the perennial plant species Chamaenerion angusti/olium a concept was deduced concerning the population dynamics of the species. The age structure was determined by counting the rings of periderm in the roots. After the establishment of seedlings vegeta
