AB  - Climate change profoundly affects crop production. Under field conditions, there is
a cycle of rainfall and rainless periods. The intervals between rainfalls have become
prolonged in certain growing areas due to climate change leading to a significant reduction in
crop production. The ability of crops to recover from drought stress depends on the species,
genotype, and the duration and severity of drought stress. Sunflowers are particularly
sensitive to drought at the germination stage. Therefore, this study aimed to develop a test to
assess the capacity of sunflower to recover from stress at the initial developmental stage. The
test was condected in rhizotrons to monitor root growth in controlled conditions. After 7 days
of drought stress, plants were re-watered to reach the control's gravimetric water content (65%
qwc). Re-watering in rhizotrons can be challenging due to the surface depth ratio, which
hinders the uniform distribution of water. To address this, we introduced a novel slow rewatering method, facilitating a more homogeneous increase in soil water content throughout
the rhizotron. For developing this test, we selected a drought-sensitive sunflower line,
subjected it to drought conditions (50% gwc), and then re-watered it to observe its recovery
capacity. Root and shoot traits between control and treatment were analyzed, including total,
primary and lateral root length, root system width and depth, leaf area, and fresh and dry
shoot weight. This test will provide valuable insights into how sunflowers recover from
drought stress, which will be very helpful in breeding programs.

AB  - The aim of this research was to determine the histological basis of the genotypic differences for drought tolerance, calculate tissue volume densities (Vv), examine the variability, and assess tissue proportions along the root maturity gradient. For the stereological analyses of root tissues four sunflower genotypes, 14 days old seedlings which were grown in rhizotrons, have been carried out on the primary (axial) root. The total length of the axial roots varied among genotypes, but not significantly. Root cross-sections were cut along the root maturity in five segments according to the principle of systematic uniform random sampling method. Cross-sections were made applying cryo-technique procedure and proportion of tissues was estimated by point-counting method. The vessel network characteristics (number and diameter of vessels) vary along maturity gradient and individual roots. Consequently, branching vessels pattern and axial conductance may limit water flow through root systems.

AB  - The root functionality is affected by numerous factors. One of the main structural parameters, the most important for functionality and adaptability, is xylem organization. Taking into account that sunflower root features have not been directly selected in breeding programs the aim of this research is to determine whether different sunflower genotypes (wild annual species and cultivated genotypes) have influence (i) on the structure of the xylem anatomy and (ii) on the xylem features along the maturity gradient. For the detailed anatomical characterization of root xylem, 14 days old seedlings which were grown in rhizotrons, have been carried out on the primary root. Root cross-sections were cut in positions sampled according to the principle of systematic uniform random sampling method. Along the root maturity, three sections per roots were made using cryotechnic procedure. Observations of the root and measurements of the vessels were carried out using the light microscope with Image Analyzing System. The obtained results of the comparative root xylem anatomy revealed significant phenotypic variability among tested genotypes. The ratio of cross-section xylem area, vessel diameter and theoretical hydraulic conductance (kh), increase along the maturity gradient for all genotypes. Significant differences in vessel size and frequency were recorded between wild species and cultivated genotypes.

AB  - Drought is a major limiting abiotic factor in production of sunflower (Helianthus annuus L.), one of the main oil crops, worldwide. Consequently, breeders are always in search of drought tolerant genotypes and getting more insight into mechanisms underlying drought tolerance. With the global environmental changes occurring, drought stress gained even more on its significance. Different and significant changes in plant morphology and metabolism occur in response to drought stress. Analysis of the root as a main plant organ for water uptake, was mainly neglected, mostly due to the diffi culties of reaching and examining it. Development of modern automated phenotyping platforms enable overcoming this problem. For the purpose of analyzing response of sunflower root system to water deprivation conditions, cultivated and wild sunflower genotypes were chosen from a vast sunflower collection located at the Institute of Field and Vegetable Crops (IFVCNS). Sunflower root architecture was analyzed by the use of the automated phenotyping platform GROWSCREEN-Rhizo located at the institute IBG-2: Plant Sciences at Forschungszentrum Jülich GmbH (FZJ). The aim of this study was to analyze the responses of different genotypes and genotypic constitutions to water defficiency conditions and to identify root trait(s) that could be used as a discriminant between genotypes that are tolerant and sensitive to low water availability.

AB  - Sunflower breeding, in the past decades, had lead to significant improvements in sunflower yield, pest resistance, and altered oil composition; however breeding is oriented towards analysis and improvement of above-ground parts, while root development has been significantly neglected. Future breeding eff orts that would be aimed at modifying root traits can result in improved crops regarding stress-tolerance and ultimately increased yields by optimizing the capacity of the plant for soil exploration (water and nutrient acquisition). Development of novel phenotyping platforms for non-invasive root analysis facilitates characterization of root architecture and investigation of developmental dynamics and root growth. Up to our knowledge, this is the first report of sunflower root phenotyping using modern phenotyping platforms.
