Abstract

Continuous cropping (CC) stress severely limits the growth and industrial development of Pinellia ternata. Epihomobrassinolide (EBR) is a natural product that widely participates in many the physiological activities of many plants. Thiamethoxam·flutolanil·azoxystrobin (TFA) has been registered as a seed coating agent in crop production. In this work, the effects of seeds soaked with EBR, seeds coated with TFA, and their co-application on the plant growth, electrophysiological information (as physiological activities related to plant electrical signals), leaf photosynthesis, plant resistance, bulb quality, and yield of CC P. ternata were evaluated. The aim of this work is to excogitate a practicable agronomic measure for ameliorating the growth of CC P. ternata. The results show that soaking the seeds with EBR or coating the seeds with TFA could effectively enhance the plant height, leaf area, and stem diameter of CC P. ternata, promote its emergence seedling ratio, and decrease its inverted seedling ratio, and their associated application was found to be more efficient. Additionally, their associated application effectively enhanced the intrinsic capacitance (IC), intracellular water metabolism, nutrient transport, and metabolic activity and decreased the intrinsic resistance (IR), impedance (IZ), capacitive reactance (IXc), and inductive reactance (IXL). Meanwhile, their associated application could reliably enhance the photosynthetic capacity and stress resistance, and effectively improve the bulb quality and yield. This study emphasizes that the associated application of seeds soaked with a 0.004% aqueous EBR solution diluted 1000 times and seeds coated with a 24% TFA flowable concentrate at 1.6 mL kg−1 seed can be used as a novel and practicable technology for alleviating the CC stress of P. ternata and ameliorating its growth, electrophysiological information, resistance, quality, and yield.

Epihomobrassinolide 和 Thiamethoxam-Flutolanil-Azoxystrobin 对三叶半夏连作压力的影响

连作（CC）胁迫严重限制了半夏（Pinellia ternata）的生长和产业发展。表禾草内酯（EBR）是一种天然产品，广泛参与许多植物的生理活动。噻虫嗪-氟唑菌酰胺-唑菌酯（TFA）已被登记为农作物生产中的种子包衣剂。在这项工作中，评估了用 EBR 浸泡的种子、用 TFA 包衣的种子以及它们的共同应用对 CC P. ternata 的植物生长、电生理信息（与植物电信号有关的生理活动）、叶片光合作用、植物抗性、鳞茎质量和产量的影响。这项工作的目的是为改善 CC P. ternata 的生长状况提出一种切实可行的农艺措施。结果表明，用 EBR 浸泡种子或用反式脂肪酸包衣种子可有效提高 CC P. ternata 的株高、叶面积和茎直径，促进其出苗率，降低其倒伏苗率，而且其相关应用也更有效。此外，它们的联合应用还能有效提高固有电容（IC）、细胞内水分代谢、养分运输和代谢活性，降低固有电阻（IR）、阻抗（IZ）、容抗（IXc）和感抗（IXL）。同时，它们的联合应用能可靠地提高光合能力和抗逆性，并有效改善鳞茎的质量和产量。本研究强调，用稀释 1000 倍的 0.004% EBR 水溶液浸泡种子，再用 1.6 mL kg-1 种子浓度的 24% TFA 流动浓缩液包衣种子，可作为一种新颖实用的技术，用于缓解 P. ternata 的 CC 胁迫，改善其生长、电生理信息、抗性、质量和产量。
