Summary Increased drought frequency and severity in a warming climate threaten the health stability of forest ecosystems, influencing structure functioning forests while having far‐reaching implications for global carbon storage regulation. To effectively address challenges posed by drought, it is imperative to monitor assess degree stress trees timely accurate manner. In this study, gradient experiment was conducted with poplar as research object, multimodal data were collected subsequent analysis. A machine learning‐based monitoring model constructed, thereby enabling duration trees. Four processing methods, namely decomposition, layer fusion, feature fusion decision employed comprehensively evaluate monitoring. Additionally, potential new phenotypic features obtained different methods discussed. The results demonstrate that optimal learning model, constructed under exhibits best performance, average accuracy, precision, recall F1 score reaching 0.85, 0.86, 0.85 respectively. Conversely, novel derived through decomposition supplementary did not further augment precision. This indicates approach has clear advantages offers robust theoretical foundation practical guidance future tree response assessment.

Abstract Understanding the timely regulation of plant growth and phenology is crucial for assessing a terrestrial ecosystem’s productivity carbon budget. The circadian clock, system genetic oscillators, acts as ‘Master Ceremony’ during physiological processes. mechanism particularly elusive in trees despite its relevance. primary secondary tree growth, leaf senescence, bud set, burst timing were investigated 68 constructs transformed into Populus hybrids compared with untransformed or controls grown natural controlled conditions. results analyzed using generalized additive models ordered-factor-smooth interaction smoothers. This meta-analysis shows that several components are associated clock. Especially core clock-regulated genes affected both field Our highlight importance trials potential clock to generate improved characteristics sustainable silviculture (e.g., reprogrammed new photoperiodic regimes increased growth).
