Utilization of a high-throughput shoot imaging system to examine the dynamic phenotypic responses of a C4 cereal crop plant to nitrogen and water deficiency over time

Abstract

HighlightA high-throughput imaging system was used to compare growth and architectural traits of sorghum grown under different environmental conditions, and validated against traditional measures of plant performance and composition.

A High-Throughput, Field-Based Phenotyping Technology for Tall Biomass Crops

“…Initially, high-throughput systems were generated to collect phenotypic data from model organisms in controlled environments such as growth chambers and greenhouses. These indoor systems are now broadly used to characterize economically important crops by employing a variety of sensors including digital RGB (Campbell et al, 2015;Fahlgren et al, 2015;Neilson et al, 2015;Ge et al, 2016), NIR Fahlgren et al, 2015;Neilson et al, 2015), hyperspectral (Ge et al, 2016), and thermal (Mangus et al, 2016) cameras, among others (Furbank and Tester, 2011).…”

“…Alternative phenomics facilities are available in which either plants are moved in their pots to the imaging/ sensor station through a conveyor belt system (Berger et al, 2010;Chen et al, 2014;Yang et al, 2014;Campbell et al, 2015;Fahlgren et al, 2015;Neilson et al, 2015;Ge et al, 2016) or structures carrying the sensors move to the plants (Granier et al, 2006;Jansen et al, 2009). In sorghum (Sorghum bicolor), high-throughput phenotyping under controlled conditions was exploited to investigate responses to drought and fertilizer use by RGB and NIR imaging (Neilson et al, 2015).…”

Utilization of Machine Vision to Monitor the Dynamic Responses of Rice Leaf Morphology and Colour to Nitrogen, Phosphorus, and Potassium Deficiencies

“…Relative growth rate (RGR) is an essential parameter to evaluate plant growth rate and is widely used in botany studies [22,23]. In this…”

“…Recently, continuous monitoring has been applied in numerous studies to study the phenotypic responses of plants to various environmental conditions [22][23][24]. Studies conducted by Poire et al [22], Neilson et al [23], and Yong-hui et al [25] reported the temporal dynamics of leaf morphology and colour during the leaf extension stage.…”

“…Studies conducted by Poire et al [22], Neilson et al [23], and Yong-hui et al [25] reported the temporal dynamics of leaf morphology and colour during the leaf extension stage. eir results also showed that different nutrient supplies resulted in various dynamic characteristics (such as the leaf extension rates and rates of colour change), which indicated that nutrient deficiency could be identified by dynamic characteristics at early stages.…”
