HLB-Resistant Citrus Interstock Trial Data

Greenhouse trial data evaluates six HLB-resistant genotypes as interstocks between susceptible 'Valencia' sweet orange scion and 'Rangpur' lime rootstock. The study measures CLas infection and titer in leaves, stem bark, and roots over 12–24 months, finding CLas movement to roots was blocked in 42% and 86% of plants using specific hybrid interstocks. Molecular, anatomical, and biometric variables were also investigated.

Use Cases

• Analyze CLas titer levels in scion, interstock bark, and rootstock tissues to compare bacterial load across different hybrid genotypes.
• Correlate dry weight of the root system with CLas + CTV infection status to quantify disease impact on plant biomass.
• Investigate changes in sieve phloem anatomy and gene expression data associated with CLas and CTV co-infection.
• Assess the blockage rate of CLas movement from scion to roots using data from F1 hybrid of C. australis × C. inodora or admixture hybrid interstocks.

Strengths

• Data originates from a controlled greenhouse experiment assessing six distinct HLB-resistant genotypes.
• Includes measurements of CLas infection and titer across three plant tissue types: leaves, stem bark, and roots.
• Study duration spans 12 to 24 months after graft-inoculation, providing longitudinal infection data.
• Licensed under CC BY 4.0 for open reuse.

Limitations

• Dataset is very small at 10.6 KB, indicating limited scope and likely a summary table rather than raw experimental data.
• Specific row count, column names, and sample data are unavailable, limiting detailed analytical reproducibility.
• Findings are from greenhouse conditions; author notes long-term field evaluation is necessary for practical assessment.
