摘要：

本研究旨在评价原状生物炭(BC) （3%)和载磷生物炭(PBC）（3%)在钒(V) (60 mg L-1)胁迫下对水稻生长情况和生理生化指标的影响。结果表明，单V处理情况下水稻植株的生长情况参数有所下降。相反，BC和PBC的加入引起了水稻生理性状的显著改善。PBC在V胁迫环境下表现良好，受试水稻地上部分鲜重和根鲜重分别比单V处理组增加82.86%和53.33%。叶片叶绿素相对含量（SPAD）比单V处理组植株提高了13.05%。此外，植物茎部和根部的抗氧化酶活性均显著高于单V处理组植株，如超氧化物歧化酶(SOD)(56.11&117.35%)、过氧化氢酶(CAT)(34.19&35.77%)和过氧化物酶(POD)(25.90&18.74%)。以上发现表明，使用BC和PBC可能触发分生组织细胞生物量积累的生物化学途径。然而，需要进一步的研究来阐明促进这种生长的潜在机制。

Abstract:

This investigation evaluated the impact of as-is biochar (BC) and phosphorous (P)-loaded biochar (PBC) (3%) on the growth and biochemical characteristics of rice under exposure to vanadium (V) (60 mg L–1).  The results indicate that rice plants exposed to a V-only treatment experienced declines in several growth parameters.  Conversely, the inclusion of BC and PBC caused noteworthy increases in physiological traits.  PBC performed well in stress environments.  Specifically, the shoot and root fresh weights increased by 82.86 and 53.33%, respectively, when compared to the V-only treatment.  In addition, the SPAD chlorophyll of the shoot increased by 13.05% relative to the V-amended plants.  Moreover, including BC and PBC improved the antioxidant enzyme traits of plant shoot and root, such as significant increases in superoxide dismutase (SOD by 56.11 and 117.35%), catalase (CAT by 34.19 and 35.77%), and peroxidase (POD by 25.90 and 18.74%) when compared to V-only amended plants, respectively.  These findings strongly suggest that the application of BC and PBC can trigger biochemical pathways that facilitate biomass accumulation in meristematic cells.  However, further investigations are required to elucidate the underlying mechanisms responsible for this growth promotion.
