Patterns of translocation of 14C-labelled assimilates during vegetative growth of Agropyron repens (L.) Beauv.

摘要: Summary 14 CO 2 was supplied to the primary shoot or a selected tiller rhizome-tiller of plants Agropyron repens (L.) Beauv. at stages development. The distribution C-labelled assimilates then followed by autoradiography and radioactive counting. During seedling growth were directed growing regions roots. With outgrowth axillary shoots, exported from daughter tillers rhizomes. Reciprocal translocation did not occur between although it rhizome-tillers shoot. In mature completely independent but continued receive small quantities assimilate main system. Shading whole plant, except for one which fed, allowed physiological reintegration system, being transferred fed rest plant. Defoliation all gave similar result in totally defoliated 14C-assimilates remained almost entirely tiller.
