Dose-response trends
Median outcome by dose band, one vote per paper. Papers differ in medium and explant, so read these as trends, not controlled optima.
Shoot regeneration & multiplication · NAA (moderate confidence)
< 0.25 mg/L80 n=1
2–4 mg/L85.6 n=4
4–8 mg/L87.7 n=4
≥ 8 mg/L91.7 n=1
Outcome keeps rising up to the highest dose reported; the optimum may lie above what papers have tested. Outcome: response (%).
Rooting · NAA (moderate confidence)
1–2 mg/L100 n=3
2–4 mg/L36.3 n=2
4–8 mg/L87 n=2
≥ 8 mg/L76 n=1
No clear dose pattern: outcomes go up and down between dose bands, so differences between papers (medium, explant, genotype) probably matter more than dose. Outcome: response (%).

How to read this report.
- Summaries combine different papers. Media, explants, genotypes and culture conditions differ, so trends are associations, not controlled comparisons.
- Grades reflect how many independent papers agree, not how good the science is. Always read the cited sentence and its paper.
- Papers without open-access full text are read from abstracts only, so some protocols will be missing.
- * close competitor: score within 15% of the leader. Doses are shown in mg/L after unit conversion.
