Coding and description of growth stages of precocious walnut in Xinjiang based on the extended BBCH scale.

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
Introduction: Xinjiang is one of the important origins of walnut ( Methods: We conducted systematic phenological observations over two growing seasons (2023 -2024) on six nine-year-old precocious walnut materials (two main cultivars and four elite strains) planted in Alar, Xinjiang. The study covered eight principal growth stages: bud development (0), leaf development (1), shoot development (3), inflorescence emergence (5), flowering (6), fruit development (7), fruit maturity (8), and senescence and dormancy (9), further subdivided into 38 secondary stages, with coded morphological photographs provided for each stage. Results: Significant differences were observed among varieties and elite strains. BT-2 had the earliest budburst, the highest number of female flowers, and reached standard fruit size first; XW-185 had abundant male flowers and could serve as a suitable pollen donor; BT-1 exhibited the highest kernel percentage and the thinnest nutshell. Correlation analysis revealed that the trait correlation patterns of BT-2 and BT-3 were relatively complex, showing opposite trends. PCA and clustering heatmap indicated clear differentiation among the six materials, classifying them into four clusters. Discussion: The BBCH_based system provides a practical tool for pollinizer arrangement, irrigation scheduling, and breeding of precocious walnuts. Complementary traits among varieties support targeted utilization, and phenological stages can guide stage_specific irrigation. However, the two_year observation period limits the assessment of long_term stability, and future research should further elucidate the interaction network between early fruiting traits and quality traits.
