Cross-sectional root anatomy of soybean (SOY ACASSA C1) under struvite and KH₂PO₄ fertilization

This dataset contains microscopic cross-sections of soybean (SOY ACASSA C1) roots collected at the end of a 3-month pot experiment investigating the effects of phosphorus fertilization on plant growth, photosynthetic performance, and yield. Plants were exposed for three months to different struvite application rates (0–20 g kg⁻¹ soil) and reference KH₂PO₄ fertilization levels (1 and 8 g kg⁻¹ soil). Root cross-sections were prepared after the experimental period to assess anatomical responses resulting from prolonged exposure to different phosphorus sources and dosages. Microscopic observations were performed using a Delta Optical Generic Pro microscope equipped with a 3 MP camera (Delta Optical, Poland), integrated with DLTCamViewer software. The dataset provides anatomical evidence supporting the evaluation of nutrient uptake and root structural adaptation to alternative phosphorus fertilizers.

本数据集收录了采自一项为期3个月盆栽试验结束阶段的大豆（SOY ACASSA C1）根系显微切片，该试验旨在研究施磷对植物生长、光合性能及产量的影响。供试作物经3个月培养，分别施加不同施用量的鸟粪石（struvite）（0~20 g·kg⁻¹ 土壤）与参照组磷酸二氢钾（KH₂PO₄）（1和8 g·kg⁻¹ 土壤）。试验结束后制备根系切片，以评估长期施加不同磷源与施用量所引发的根系解剖学响应。显微观测采用波兰Delta Optical公司出品的Delta Optical Generic Pro显微镜，该设备搭载300万像素摄像头并集成DLTCamViewer软件。本数据集提供了解剖学证据，可用于评估养分吸收情况以及根系对替代磷源肥料的结构适应性。
