The ability of roots to penetrate hard soil is important for crop productivity but specific root phenes contributing to this ability are poorly understood. Root penetrability and biomechanical properties are likely to vary in the root system dependent on anatomical structure. No information is available to date on the influence of root anatomical phenes on root penetrability and biomechanics. R...
This study was conducted to evaluate the effects of paclobatrazol and cycocel on some quantitative and qualitative traits of zinnia. Seedlings were transplanted on Horticulture Department Farm , College of Agriculture, Isfahan University of Technology. The experiment was carried out in the framework of randomized complete block with 3 replications. Triats which were studied included plant heigh...
Fine roots acquire essential soil resources and mediate biogeochemical cycling in terrestrial ecosystems. Estimates of carbon and nutrient allocation to build and maintain these structures remain uncertain because of the challenges of consistently measuring and interpreting fine-root systems. Traditionally, fine roots have been defined as all roots ≤ 2 mm in diameter, yet it is now recognized t...
Mechanical impedance is a primary constraint to root growth and hence the capture of soil resources. To investigate whether rooting depth length under mechanical caused by compaction are correlated we evaluated 12 maize lines at two field sites. distinguish between lateral nodal roots, roots were sorted into different diameter classes. Coarse had diameters >1 mm represent axes. Greater proporti...
In the letter ‘Fine roots – functional definition expanded to crop species?’ Dr Zobel emphasizes the importance of heterogeneity within crop-root systems. We agree. The importance and quantification of architectural and functional diversity of the fine roots of all plant species was a central point in our article ‘Redefining fine roots improves understanding of below-ground contributions to ter...
in order to investigate the effect of root pruning in morphological and physiological characteristics of juniperus excelsa seedlings an experiment was carried out on transplanted one year-old seedlings. treatments included root pruning intensities (1-slight pruning (2-moderate pruning and 3- control (no root pruning)) .experiment design was completely randomized design. each treatment included ...
