Distribution patterns of peanut roots under different durations of early season drought stress

Root distribution patterns of peanut genotypes with different drought resistance levels under early‐season drought stress

“…Many studies have investigated root growth using an auger method (Jongrungklang et al., ; Koolachart et al., ; Songsri et al., ). By studying root growth characteristics in a rhizobox with a needle board, the root growth patterns and morphology are more easily defined (Thangthong, Jogloy, Pensuk, Kesmala, & Vorasoot, ) and allow researchers to compare and contrast different genetic material. Yet, this method should be coupled with other field observations.…”

“…Many studies have investigated root growth using an auger method (Jongrungklang et al, 2012;Koolachart et al, 2013;Songsri et al, 2008). By studying root growth characteristics in a rhizobox with a needle board, the root growth patterns and morphology are more easily defined (Thangthong, Jogloy, Pensuk, Kesmala, & Vorasoot, 2016) and drought stress (■) treatments of each layer for two soil layers identified as upper soil layer between 0 and 30 cm of soil depth and lower soil layer between 30 and 110 cm of soil depth. The experiment was conducted in first season (a) during October-December 2014 and second season (b) during January-March 2015; each layer plotted on mean root length and standard error by half-size of rhizobox data.…”

Genotypic variation in root distribution changes and physiological responses of sugarcane induced by drought stress

“…1). The detailed method was clearly described in the previous studies (Thangthong et al, 2016; Thangthong et al, 2017), and the method was briefly described herein.…”

“…The front side of the boxes could be opened to see the transparent window. This method has been used to study root systems in some plant species, such as peanut (Thangthong et al, 2016; Thangthong et al, 2017) and Jerusalem artichoke (Puangbut et al, 2018).…”

“…The use of split-root systems to monitor the effect of root distributions on the development of the root system is very interesting (Neumann et al, 2009). The rhizobox is effective for displaying the characteristics of the root distribution and this method has been used in many plant species such as peanuts (Thangthong et al, 2016; Thangthong et al, 2017) and Jerusalem artichoke (Puangbut et al, 2018) in which different varieties showed differences in the root distribution patterns. The information on the changes in root distribution patterns under well-water condition and drought condition for characterization of sugarcane genotypes is still lacking.…”
