Root system architecture (RSA) describes the dynamic spatial configuration of different types and ages of roots in a plant, which allows adaptation to different environments. Modifications in RSA enhance agronomic traits in crops and have been implicated in soil organic carbon content. Together, these fundamental properties of RSA contribute to the net carbon balance and overall sustainability ...

in tunisia, kalâat el andalous irrigated district is one of the most affected areas by salinization. the objective of this study was to predict the root zone salinity (over 10 years) in this area using the saltmod simulation model for subsurface drainage system. saltmod is based on water balance, salt balance model, and seasonal agronomic aspects. in the pilot area, irrigated vegetables crops s...

Plant root systems often have complex branching patterns. Models indicate that a complex architecture is only required for the acquisition of immobile resources, such as phosphate; mobile ions, notably nitrate, can be effectively taken up by very restricted root systems. We have tested this prediction using the axr4 mutation of Arabidopsis thaliana, the principal phenotypic effect of which is t...

An investigation was carried out for fifteen plant species, cultivated widely as vegetable crops in Bangladesh, belonged to six different families to measure their affinity in harbouring symbiotic association with mycorrhizal fungi. Fourteen out of the fifteen species were having developed VA-mycorrhizal colonization in their root tissues with a range of 7% to 98%. All the soil samples tested w...

Brassica crops infected by Plasmodiophora brassicae can produce root galls (clubroots) and be prevented from growing normally. To understand the series of changes that occur in the host root during root gall production, the resistance character of 21 Chinese cabbage lines were identified and then resistant and susceptible lines were used for infection observation. Hydroponic technology system w...

The aim of the present study was to evaluate the response of grain yield, phosphorus (P) use efficiency (PUE, g yield g–1 P available) and related root traits of wheat and pea to different P availabilities in a high yielding environment (e.g.: yield higher than 10 Mg ha-1 for wheat). Two experiments were conducted in southern Chile. Treatments consisted of the combination of (i) two crops (spri...

Different methods have been proposed for in situ root-length density (RLD) measurement. One widely employed is the time-consuming sampling of soil cores or monoliths (MO). The profile wall (PW) method a less precise, but faster and laborious alternative. However, depth-differentiated functions to convert PW RLD estimates MO measurements not yet reported. In this study, we perform regression ana...

Goal. The study of the influence design parameters cleaner heads root crops from remains chaff on basis analysis a mathematical model that describes its plane-parallel movement in longitudinal-vertical plane under external disturbance form fluctuations ordinates longitudinal profile field. Methods. Theoretical calculations operation rear-mounted were performed computer using PTC Mathcad 15 soft...

Orphanor understudied-crops are mostly staple food crops in developing world. They are broadly classified under cereals, legumes, root crops, fruits and vegetables. These under-researched crops contribute to the diet of a large portion of resource-poor consumers and at the same time generate income for small-holder farmers in developing countries, particularly in Africa. In addition, they perfo...
