''2,4 - D widely used to kill dicotyledonous weeds , does not affect mature moocotyledonous plants. ''
why does it afffect oly dicotyledonous weeds and not monocotyledonous weed.?
required for growth
(1) Oxygen provides the medium for enzymatic
activities needed for growth
(2) Water helps in releasing metabolic energy
essential for growth activities
(3) Turgidity of cells help in extension growth
(4) Only microelements are required by plants for
the synthesis of protoplasm and act as source
of energy
