Root studies on chickpea ( Cicer arietinum L.) A .Ganjealia and M. Kafib a and b contributions from Research Center for Plant Science and Faculty of Agriculture Ferdowsi University of Mashhad – Iran respectively Abstract Although ideal type and architects of plants are well documented in the literature, but there is little evidence on root aspects of plant. In order to study of morph physiologic of roots, three separately experiments were conducted in research glasshouse of Ferdowsi University of Mashhad (FUM). Primary results showed that genetic variation for root character’s is considerable in seedling stage and it seems that at the autotrophic or early growth stage, root growth strongly dominants to the shoot growth. In experiment 2, Uniform changes were not observed at different growth stages, and a genotype could not keep it’s performance for a trait throughout of growth season. So, if a trait is aim, screening must be do in more effective phonology of growth.. In seedling stage, there were significant linear regression correlation between TRL with RV, RA, NLR and RDW, but We didn\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\'t find any correlation between root traits at seedling stage with the same traits at another phenology stages. In third experiment, there were different spatial and temporal patterns for chickpea root growth. Root growth rate was highest on special time for each layer of soil profile. In both genotypes, RLD decreased with increasing soil depth. Results showed that more distribution of root system on upper soil layers (0-40 cm) is the root growth strategy of chickpea plants, and so, soil management on this layer is very important.
