in first experiment DC-85-5 and Sahand cultivar produced highest and lowest leaf length and in second experiment C-87-19 and Sahand cultivar had highest and lowest total leaf area. JMicroVision contains tools having various degrees of automation in order to handle with complex and varied images. Also Yosef, DC-85-5, C-87-10 and Nosrat genotypes had highest root dry weight and Val-fajr, Sahand and Nimruz genotypes had lowest root dry weight. Nimruz cultivar in filter paper with 139.3 mm and Sahand cultivar in gel chamber with 39 mm, produced the lowest total root length. Results showed that C-87-10 had highest total root length with 283 mm total root length in filter paper and 226 mm in gel chamber. The genotypes were compared by total root length, root dry weight, shoot dry weight, root diameter. The rest of germinated seeds were put into distilled water by use of rolled filter paper. After seeds germination in petri dishes, some seeds were transferred into gel chamber. A completely randomized design with three replications was used for each experiment. JMicroVision contains tools with different degrees of automation to manage complex and varied images. It has an intuitive user interface with powerful features and supports very large images. In order to investigate root growth of 18 barley (Hordeum vulgare) genotypes at seedling growth stage, two separate experiments were conducted in the Faculty of Agriculture, Ferdowsi University of Mashhad in 2012. JMicroVision has been designed to describe, measure, quantify and classify components of all kinds of images. However the positive effects of these forests on reducing damages of dust storms should not be ignored.The role of root growth on increase of yield is an important subject that is considered by plant breeders. This results showed that severe reduction of groundwater table has happened in recent decade because of planting Haloxylon. JMicroVision is an image analysis toolbox for measuring and quantifying components of high-definition images. The reduction of groundwater table was about 0.46 meter in the first study period (1992-2001) and 0.93 meter in the second study period (2002-2012) so that the reduction of groundwater level in the second study period was about 2 times bigger than the first study. The results showed that the number of Haloxylon plants in the study area was equal to 3746291 and the amount of groundwater evacuation by these plants was equal to 56.194 Mm3. Then groundwater level status was determined using GMS 8.3 software and MODFLOW model. Then using minimum water requirement of each plant, estimated with lysimeter, the number of surplus plants was determined based on their water requirement and rainfall of the region. For doing the study, at first the number of Haloxylon plants was determined in these forests using satellite images and JMicroVision software. The purpose of this study was investigation of the effect of Haloxylon planted forests on groundwater resources in Jafarieh plain. Different species of Haloxylon are compatible with desert condition and can use groundwater resources due to deep roots and proper structural condition. Investigation of the effect of plant community on limited water resources of deserts is an important issue in water resources management.
