질소와 뿌리의 수명
본 글은 "Rapid decline in nitrate uptake and respiration with age in fine lateral roots of grape: implications for root efficiency and competitive effectiveness" Astrid Volder, David R. Smart, Arnold J. Bloom and David M. Eissenstat의 부분 발췌글임.(전문 : B203_Rapid decline in nitrate uptake and respiration with age in fine lateral roots of gr)
Fig. 3 Nitrogen concentration of 3309 C rootstock roots of different ages. Roots were traced on acetate windows to assess root age (see the Materials and Methods section). When necessary, roots of close age classes were pooled and a mean age was assigned based upon root mass of each age class in the sample. Pooling was not necessary for roots < 25 d old.
질소량이 10ppm을 기준하여 많으면 뿌리수명이 급격히 줄어든다.
