Localized phosphorus promotes nutrient productivity of Brassica chinensis genotype with strong root morphological plasticity

Crops adjust root morphological and/or exudation traits in response to phosphorus (P) availability and localized P, governing crop productivity. However, how the intraspecific plasticity of P-acquisition strategies influences plant adaptation P fertilization across doses remains obscure. Root were assessed Brassica chinensis L. Xiaqing Yanchun grown soil with four mineral levels (0, 15, 24, 30 kg ha−1) broadcasted two (15 24 characterize efficient relation large The genotype stimulated growth roots specific lengths increased acid phosphatase carboxylates under 15 ha−1 compared those soil. Conversely, only elongation crops fertilized ha−1. local P-rich ha−1, but longer former than latter genotype. Localized at level, length density patchy zone promoted acquisition Yanchun. In conclusion, exhibited strong low application Nutrient-efficient coupling is important increase yield save fertilizer vegetable cropping systems.
