Despite the widespread co-occurrence of subsoil acidity and compaction, interaction between these factors their combined effects on root system development under water-limited conditions is poorly understood. This study aimed to investigate how removal soil strength influenced examine relationships properties shoot growth field conditions. Images were obtained in situ by using rhizotron facilities assess temporal improvement through loosening lime incorporation wheat 2018 season. Following this, we examined relationship enhanced systems, water nutrient uptakes, overall crop performance. The results indicated that improved significantly planar length density (pRLD) elongation proliferation roots subsoil. Regressing tree analysis suggested had a more dominant influence pRLD compared pH or aluminium — leading higher uptake, head yield. In addition benefit loosening, treatment acidity, promoting continuous with hairs, allowing plants access previously unavailable nutrients improve yield further. highlights critical role managing multiple constraints for optimising productivity. this study, integration images data provided deeper understanding root-soil interactions which could be useful developing sustainable management practices optimise productivity challenging

Genetic control of root morphology in response to nitrogen across rapeseed diversity

Physiologia Plantarum, Journal Year: 2024, Volume and Issue: 176(3)

Published: May 1, 2024

Abstract Rapeseed ( Brassica napus L . ) is an oil‐containing crop of great economic value but with considerable nitrogen requirement. Breeding root systems that efficiently absorb from the soil could be a driver to ensure genetic gains for more sustainable rapeseed production. The aim this study identify genomic regions regulate morphology in response nitrate availability. natural variability offered by 300 inbred lines was screened at two experimental locations. Seedlings grew hydroponically low or elevated levels. Fifteen traits related biomass production and were measured. On average across panel, level increased root‐to‐shoot ratio lateral length. A large phenotypic variation observed, along important heritability values genotypic effects, genotype‐by‐nitrogen interactions. Genome‐wide association bulk segregant analysis used loci regulating traits. first approach nominated 319 SNPs combined into 80 QTLs. Three QTLs identified on A07 C07 chromosomes stable levels and/or second involved genotyping groups individuals F2 population created crossing accessions contrasting lengths. These found tails distribution. Co‐localized both mapping approaches covered chromosomal region A06 chromosome. QTL contained some genes putatively organogenesis represent selection targets redesigning rapeseed.

Traits and trade-offs: dissecting nitrogen use efficiency in maize using plant modeling

Divide and conquer: Using RhizoVision Explorer to aggregate data from multiple root scans using image concatenation and statistical methods

Published: July 10, 2024

Abstract Roots are important in agricultural and natural systems for determining plant productivity soil carbon inputs. The collection of root samples from the field their subsequent cleaning scanning a water-filled tray ranging size 5 to 20 cm, followed by digital image analysis has been commonly used since 1990s measuring length, volume, area, diameter. However, one common issue neglected. Sometimes, amount roots sample is too much fit into single scanned image, so divided among several scans. There no standard method aggregate measurements across scans same sample. Here, we describe validate two methods standardizing multiple scans: concatenation statistical aggregation. Both rely on file naming conventions identify that belong Image refers combining images larger while maintaining original resolution. We developed Python script identifies which returns single, concatenated every set directory. These (combining up 10 scans) were processed with RhizoVision Explorer, free open-source software estimating traits images, settings. An R was can rows data belonging Explorer files apply correct such as summation, weighted average appropriate measurement types return row each compared using example switchgrass, poplar, various tree ericaceous shrub species northern peatland Arctic.
