34 Elucidating the genetic control of rooting behaviour under water-deficit stress is essential to 35 breed climate-robust rice cultivars. Using a diverse panel of 274 indica genotypes grown 36 under control and water-deficit conditions during vegetative growth, we phenotyped 35 traits, 37 mostly related to root morphology and anatomy, involving ~45,000 root scanning images and 38 nearly ~25,00...
Soybean [Glycine max (L.) Merr] is an important legume crop and its yield largely depends on root architecture (RA) and biological nitrogen fixation (BNF). However, the relationship between RA and BNF, and its genetics behind remain unclear. Here, two soybean genotypes contrasting in RA and their 175 F9:11 recombinant inbred lines (RILs) were evaluated in field. The shallow-root parent, JD12, h...
Seed germination has an important role in the life cycle of plants and critical stages of the growth cycle, establishment and final yield. Seed germination is the most critical stage of seedling establishment which ultimately determines the successful production of the product. Salinity is one of the environmental factors reducing crop production in the world. Saline soils or irrigation the...
The aim of the present study was to dissect the genetic inheritance and interplay of root, shoot and heading attributes for a better understanding of these traits in crop production. For this, we utilized quantitative trait loci (QTL) and candidate gene analysis approach using a second filial (F2) population originated from a cross between spring cultivar Cheri and wild barley accession ICB1811...
in order to assess the heritability of short vegetation period (early maturity) of sugar beet hybrids, an experiment was carried out in randomized complete block (rcb) design with 4 replications in abdolrasoul motahari agricaltural research station of sugar beet seed institute, karaj, iran in 2009. in this research, the heredity of the traits in testcrosses derived from crosses of 18 half sib f...
Root diameter, a critical indicator of root physiological function, varies greatly among tree species, but the underlying mechanism of this high variability is unclear. Here, we sampled 50 tree species across tropical and temperate zones in China, and measured root morphological and anatomical traits along the first five branch orders in each species. Our objectives were (i) to reveal the relat...
Identification of quantitative trait loci (QTLs) associated with rice root morphology provides useful information for avoiding drought stress and maintaining yield production under the irrigation condition. In this study, a set of chromosome segment substitution lines derived from 9311 as the recipient and Nipponbare as donor, were used to analysis root morphology. By combining the resequencing...
Frequency of irrigation to the crops is the key factor for proper growth and economic yield. Therefore, in the current study growth of broccoli plants was investigated under different irrigation levels in pot culture condition. Five levels of irrigation schedules were applied including I0 [Non-irrigation control], I1 [Irrigation up to 15 days after transplanting (DAT)], I2 [Irrigation up to 30 ...
Morphological plasticity of ectomycorrhizal (EcM) short roots (known also as first and second order roots with primary development) allows trees to adjust their water and nutrient uptake to local environmental conditions. The morphological traits (MTs) of short-living EcM roots, such as specific root length (SRL) and area, root tip frequency per mass unit (RTF), root tissue density, as well as ...
Aluminum is one of the most abundant elements in soil that become soluble form as Al+3 in high acidic soils, absorbed through the roots and affect on plants growth. Evaluating plant tolerance to environmental stresses in seedling stage is an important factor for selecting plant to cultivate in different conditions. In order to evaluate tolerance of 83 durum wheat advanced line at aluminum toxic...
