This study was conducted to evaluate the genetic diversity of sugar beet half sib inbred lines (48 lines and one control cultivar) under water stress (200mm of class A evaporation pan) in field conditions in a randomized complete block design with three replicates in Khorasan Razavi Agricultural and Natural Resources Research and Education Center in 2015. In this research, traits such as root y...
of Research Achievements and Impacts In the past year significant progress was achieved in all activities of the project. Numerous genotypes were screened for root traits conferring adaptation to drought and low soil fertility. These include inbred backcross lines developed at Zamorano and IIAM to introgress superior root traits into elite cultivars, and a range of genotypes from Africa and the...
the study was conducted to evaluate the effect of seed priming on root growth of two barley cultivars (hordeum vulgare l.) under salinity stress was performed in phytogel. the treatments included two cultivars of barely (yusuf and maquie), levels of seed priming (control, hydro-priming and priming with 4.35 g l-1 of urea) and four levels of nacl salinity stress (0, 0.2, 0.3 m). the experiment w...
light is one of the important environmental factors seriously affecting plant growth. given the availability of roots in aeroponic system, the influence of various light rays emitted towards the root zone of anthurium was studied. foliar spray of calcium nitrate in concentration of 10 mm was tried because of the high importance of calcium element in enhancement of vase life and strength of cut ...
There is interest in discovering root traits associated with acclimation to nutrient stress. Large root systems, such as in adult maize, have proven difficult to be phenotyped comprehensively and over time, causing target traits to be missed. These challenges were overcome here using aeroponics, a system where roots grow in the air misted with a nutrient solution. Applying an agriculturally rel...
root depth and distribution have an important role in drought resistance and optimization of moisture content of soil. this research was carried out in order to consider of root response of triticale genotypes to water stress and recognition of root trait that can effective in resistance of water stress. this experiment was in a factorial experiment based on completely random design on the year...
Understanding root processes at the whole-plant or ecosystem scales requires an accounting of the range of functions within a root system. Studying root traits based on their branching order can be a powerful approach to understanding this complex system. The current study examined the highly branched root system of the ericoid plant, Vaccinium corymbosum L. (highbush blueberry) by classifying ...
The aims of this study were to investigate genotypic variations in root traits at phytomer level of wheat varieties and for recommending a few root traits as selection parameters in future breeding programs. Two separate experiments were conducted to measure their root traits for hydroponically grown wheat plants. In Experiment 1, main axis length, root hair density and diameter differed from p...
