Fractal Analysis For Morphological Description Of Corn Roots Under Nitrogen Stress, John Settimi, Bahman Eghbal, Jerry Maranville, Anne Parkhurst
John R. Settimi
A means of quantification of plant root branching, specifically under stress, is of importance for evaluating the contribution of plant roots to water and nutrient uptake and subsequently plant growth. An experiment was conducted to describe the morphology of corn (Zea mays L.) root systems using fractal analysis and also to determine if a roots fractal dimension (D) is altered by N stress. Corn genotypes (B73 ✕ LHI05 and N74 ✕ Mo17) were planted in peg boxes, 1.2 m long, 1.2 m deep, and 0.05 m wide filled with 20:80 soil to sand mixture and were grown with N rates …
