Table 1 Seed composition and nitrogen harvest index of Aviso and Oase under ample or low N supply

From: The contrasting N management of two oilseed rape genotypes reveals the mechanisms of proteolysis associated with leaf N remobilization and the respective contributions of leaves and stems to N storage and remobilization during seed filling

  1. The plants were supplied with an ample (HN, 3.75 mM) or low (LN, 0.375 mM) nitrate concentration. The N amount in seed is estimated in milligrams. C: N ratio: ratio C: N in seeds; NHI: N Harvesting Index (mg N in seeds per mg N in shoot). The seed composition (percentage of proteins and fatty acids) and the oil composition (percentage in oleic, linolenic, linoleic and erucic acids) was determined by NIRS method. Asterisks represent significant differences between N treatments and hashes represent significant differences between the two genotypes (n = 4 plants; #,*= p < 0.05; **= p < 0.01).
