| Abstract:
The involvement of carbon and nitrogen allocation in the flowering process of the strawberry cv. ‘Toyonoka’ induced by low nitrogen, was investigated by using 13C- and 15N-tracers. The allocation pattern of C and N in flower-induced plants by low N was marked by 1) a carbon content that was also low, 2) a recently fixed C that is primarily allocated to roots, and 3) a recently absorbed N that is allocated more to crowns, young leaves, and shoot apices than it is to leaves. | |
