A litmus test for plant consciousness: Pattern-Temporal Synergy in a relation-first ontology.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Plant cognition has progressed from anecdote to rigor, yet the field still lacks a quantitative test for when distributed plant activity crosses into unified - perhaps conscious - processing. I introduce Pattern-Temporal Synergy (PTS), a substrate-agnostic metric rooted in Dynergeia, a relation-first ontology in which consciousness is reflexive coherence among five universal patterns - self-reference, division-creation, information integration, responsiveness, and flux - phase-locked inside a system's binding window (τ). Each pattern is operationalized with established signal-processing measures; their median strength is multiplied by their mean synergy and released only if a τ-specific coherence gate is met. Three preregistered hypotheses anchor the study: H1 baseline PTS > 0 in intact plants; H2 4% diethyl-ether collapses PTS below threshold ϕ; H3 PTS rebounds on wash-out. A multispecies protocol - Mimosa pudica, Arabidopsis thaliana, Picea abies - combines 64-channel surface electrodes, glutamate-sensitive Ca2+ imaging and micro-optode O2/heat-flux probes. Sliding 3 ×τ windows with phase-shuffled surrogates yield z-scored PTS trajectories, adjudicated by preregistered effect-size criteria. By turning decades of qualitative insight into falsifiable numbers, PTS offers plant biology a litmus test for conscious-level processing, directly challenges Integrated Information Theory and supplies a road-map for cross-kingdom comparisons - including neuromorphic silicon. Confirmatory results would shift debates on plant sentience from speculation to data; null results would equally refine what consciousness requires.
