Leaf size regularities in Festuca pratensis from the systemic viewpoint

摘要: The influence of internal systemic factors on the size fully grown leaves was investigated in Poaceae plant Festuca pratensis. Using approach, length different ordinal numbers along a shoot and same number shoots were measured, analysing groups categorized as subsystems by authors. It found that regularly increased with an increase shoot. explanation could be trophic relationships: donor increases, which expresses factor, i.e. more assimilates are received younger leaves, thus vegetative developmental programme has been implemented. Another tendency discovered well: numbered also number. This is manifested apical subsystems, while leaf distribution basal subsystem ir...
