Root growth ofRumexandPlantagospecies in compacted and waterlogged soils

Abstract: The root patterns of Rumex palustris (Sm.), Rumex acetosa (L.) and Plantago major (L.) ssp. major, three species occurring in the river forelands, were studied in experimentally waterlogged or drained compacted soils and compared with specimens growing in drained loosely packed-soils as a control. A modified method for endoscopy in root boxes was developed. The species studied showed different patterns of root development as a result of soil waterlogging or compaction. R. palustris was the least sensitive to w… Show more

“…While aerenchyma formation can overcome the eects of hypoxia, it may also weaken the root structure. After ooding, when the soil becomes more compacted, the aerenchymatous structure may collapse under external pressure and the amount of functional root tissue may be reduced (Engelaar et al, 1993). In addition, trampling by cattle increases soil density in the Flooding Pampa (Taboada and Lavado, 1993).…”

“…The effects of root anatomical phenes on penetration and root biomechanics are not well understood ( Lynch and Wojciechowski 2015 ). Some phenes such as RCA can overcome the effects of drought by improving soil exploration ( Zhu et al , 2010 ), but may also weaken the root structure ( Engelaar et al , 1993 ; Striker et al , 2006 ). Reduced cortical cell file number (i.e.…”

“…A system of interconnected aerial spaces (aerenchyma) provides a pathway of lower resistance that facilitates oxygen transport from aerial shoots to the roots, allowing root growth and soil exploration under anaerobic conditions (Armstrong 1979; Colmer & Greenway 2005). However, the formation of additional aerenchyma in the root cortex produces large variations in the internal structure of the roots (Justin & Armstrong 1987), which might lead to a trade‐off in root mechanical strength necessary to resist both natural and anthropogenic soil compressive forces (Engelaar, Jacobs & Blom 1993a; Striker et al . 2006).…”

“…Furthermore, in many grassland regions of the world, root systems could be exposed to the combination of antagonistic stress factors such as flooding and soil compaction as part of the natural disturbance regime (Soriano 1992). In such a context, the advantage of increased root porosity for oxygenation could endanger the mechanical strength of the roots, which helps them resist trampling (Engelaar et al . 1993a,b; Striker et al .…”
