From: A novel grass hybrid to reduce flood generation in temperate regions
Changes over two consecutive years to root system size in Lolium and Festuca species and their hybrids.
Box A shows significant degeneration (P < 0.001) in overall root system size following an initial 6 months establishment of forage grass cultivars Lolium perenne cv AberStar (Lp), Festuca pratensis cv Bf993 (Fp), L. perenne x F. pratensis cv Prior (LpxFp), Lolium multiflorum cv AberEpic (Lm), Festuca arundinacea cv Dovey (Fa) and L. multiflorum x F. arundinacea var glaucescens cv 99/1 (LmxFa) throughout one meter soil columns (n = 4) observed on April 16th and September 17th over two growing seasons. Boxes B-E "dissect" these root systems (shown in A) into consecutive 10-cm fractions distributed along the one meter soil columns to show significant (P < 0.001) root growth and senescence (scale 0 = no visible root system; 4 = very extensive root systems) (n = 4) at the same timepoints25.
