significant decrease in root volume would contribute to greater root density, leading to smaller mechanical impedance and greater penetrate capacity when T . 406 plant roots are elongated. There is a consensus that stronger root vertical growth ability could

of light by as much as 50%, mainly due to the mechanical impedance of light by greenhouse support structures and nets ( Fisher and Runkle, 2004 ). Plants in general have the ability to adjust to changes in environmental conditions such as low
balance while restricting Na + absorption in relation to soils with low Ca 2+ ( Yamada et al., 2007 ). Soil ion exchange capacity, mechanical impedance of roots, soil texture, and/or the effect of soil matric potential can influence the availability of
Root growth and RSA are affected by edaphic and genetic factors. Soil characteristics such as mechanical impedance, moisture content, and nutrient availability can affect the size of the root system ( Gioia et al., 2015 ; Hund et al., 2009 ; Jin
