| Abstract:
Entire six-years-old red raspberry (Rubus idaeus L.) plants cv. Heritage were excavated from a commercial orchard in Angol, Chile (Southern hemisphere) during mid-winter. Plants were divided into roots, crown, floricanes and buds. Dry weight (DW), nitrogen concentration (Nc) and total nitrogen content (TNC) were measured on each sample. Floricanes represented 35% of total plant DW and roots 30%. The highest Nc was detected in fine roots (2.2%) and buds (1.9%). Canes had 0.86 %Nc and crown only 0.62%. TNC was higher in roots than in canes, indicating that they are the main N reserve organs during winter. | |
