Soil moisture and compaction are important factors for growth and development of plant root. This study was conducted as a nested design with two factors and three replications to investigate the beha...
Dynamics of Root Border Cells in Rhizosphere Soil of Zea mays L.:Crushed Cells during Root Penetration, Survival in Soil,and Long Term Soil Compaction Effect
Detached cells Maize Rhizosphere Root cap Sloughed root cap cells Soil compaction Soil mechanical impedance
2009/7/23
Plant roots release mucilage and root border cells (RBCs) into rhizosphere, which function as a complex at the root-soil interface. The dynamics of RBCs in rhizosphere soil, however, remains unknown. ...

Effect of soil compaction on root system development and yields of tall fescue
tall fescue yields roots image analysis soil compaction tractor traffic
2008/11/20
Soil compaction caused by tractor traffic is one of the most important factors responsible for environmental degradation and leads to plant yields reduction. It is a serious problem for perennial crop...
Response of spring barley to changes of compaction and aeration of sandy soilunder model conditions
soil bulk density oxygen diffusion rate (ODR) root growth yield spring barley
2008/11/18
The response of grain yield and root growth of spring barley to changes of compaction and aeration of a sandy soil was studied under model conditions. The experiment was done using plots of 1 m x 1 m....
