Plant root systems have a key role in ecology and agronomy. In spite of fast increase in root studies, still there is no classification that allows distinguishing among distinctive characteristics within the diversity of rooting strategies. Our hypothesis is that a multivariate approach for "plant functional type" identification in ecology can be applied to the classification of root systems. T...
In order to study effect of the various levels of drought and salinity stress (0, -4, -8, -12, -16 bar) on morphological, physiological and biochemical traits of Atriplex halimus in seedling stage under hydroponic culture, two separated experiments were conducted as completely randomized design in three replications in hydroecology laboratory of Gonbad Kavous University...
Phosphorus (P) is an important element for crop productivity and is widely applied in fertilizers. Most P fertilizers applied to land are sorbed onto soil particles, so research on improving plant uptake of less easily available P is important. In the current study, we investigated the responses in root morphology and root-exuded organic acids (OAs) to low available P (1 μM P) and sufficient P ...
in order to evaluation of morphological selection criteria for salt tolerance screening in wheat (t. aestivum l.) a factorial experiment based on completely randomized design in 3 replications were conducted under greenhouse condition. salinity treatments involved 4 levels: s=1.3dsm-1 (control), 5, 10, 15 dsm-1 from calcium chloride and sodium chloride with 10:1 (na: ca ratio) and another facto...
Grafting is an ancient technique that involves the physical joining of genotypically distinct shoot and root systems, in order to achieve a desirable compound plant. This practice widely used modern agriculture improve biotic abiotic stress tolerance, modify plant architecture, induce precocious flowering rejuvenate old perennial varieties, boost yield, more. Beneficial new rootstock-scion comb...
