摘要

亚洲大豆锈病(ASR)是由厚根Phakopsora pachyrhizi引起的大豆锈病,对大豆造成巨大的产量损失,镍(Ni)具有防治潜力。本研究通过两个试验,评价了不同镍含量的大豆种子对ASR的防治效果。在试验1中,用60或100 gNi·ha-1溶液对植株喷施3次,获得不同Ni含量的种子。植物喷水作为对照处理。实验2在实验1获得的种子(T1 = 0.9 μgNi·seed-1, T2 = 1.2 μgNi·seed-1, T3 = 1.6 μgNi·seed-1)的V4生长期接种肿根假单胞菌。测定接种后16 d ASR严重程度(DAI)和接种后8、16 d时叶绿素(Chl) a荧光参数。与T1治疗相比,T2和T3治疗的ASR严重程度分别降低了64%和47%。ASR对光合机构有不利影响。侵染小叶中光系统ⅱ利用光的效率降低,而非调节形式耗散的能量增加。接种植株的T1、T2和T3处理的Chl - a荧光参数无显著差异,这可能是由于肿根菌的生物营养生活方式与ASR严重程度较低有关。综上所述,本研究强调了利用高镍含量种子作为ASR综合管理控制工具的潜力。

Nickel-enriched soybean seeds generate plants more resistant to Asian soybean rust
Asian soybean rust (ASR), triggered by Phakopsora pachyrhizi, can cause great yield losses on soybean and nickel (Ni) has potential to control this disease. This study evaluated the effect of using soybean seeds with different Ni contents on ASR control by performing two experiments. In experiment 1, seeds with different Ni contents were obtained by spraying plants three times with solutions containing either 60 or 100 gNi·ha–1. Plants sprayed with water served as the control treatment. In experiment 2, plants originated from seeds obtained in experiment 1 (T1 = 0.9 μgNi·seed–1, T2 = 1.2 μgNi·seed–1, and T3 = 1.6 μgNi·seed–1) were inoculated with P. pachyrhizi at the V4 growth stage. The ASR severity was evaluated 16 days after inoculation (DAI) and the chlorophyll (Chl) a fluorescence parameters at 8 and 16 DAI. The ASR severity decreased by 64 and 47% for treatments T2 and T3, respectively, in comparison to T1 treatment. The photosynthetic apparatus was negatively affected by ASR. The efficiency of the use of light by photosystem II decreased while the energy dissipated by nonregulated form increased in the infected leaflets. There was no significant difference for Chl a fluorescence parameters for T1, T2, and T3 treatments applied to inoculated plants probably due to the biotrophic lifestyle of P. pachyrhizi associated with lower ASR severity. In conclusion, the potential of using seeds with higher Ni content as a tool for ASR integrated management control is highlighted in this study.
