摘要:
以菟丝特为供试药剂，设置体积分数0，5，10，15 mL/L，施药后10 d测定日本菟丝子及寄主野蔷薇的抗氧化酶（SOD，POD，CAT）活性、渗透调节（可溶性糖SS、可溶性蛋白SP、淀粉ST）和膜脂损伤（MDA）物质含量等生理指标，药后10，20，30 d测定日本菟丝子与野蔷薇外观形态指标，药后30 d测定防治效果与药害指标，探究药剂体积分数与药后时间对日本菟丝子防治效果及其寄主安全性的影响。结果表明：（1）菟丝特处理体积分数对日本菟丝子和野蔷薇的抗氧化酶活性、渗透调节和膜脂损伤物质含量均有影响(P<0.05)，10 mL/L处理日本菟丝子SOD，POD，CAT活性最大，15 mL/L处理日本菟丝子的ST和SP含量低而MDA含量最大，但10 mL/L处理可使寄主叶绿素含量恢复且生理损伤较小。（2）药后10 d日本菟丝子吸器直径生长抑制率高，20 d吸器数和藤茎直径生长抑制率高，30 d吸器和藤生长抑制率低于10，20 d，药后10—30 d均可缓解甚至解除因日本菟丝子寄生对寄主株高、冠幅、叶数和嫩枝的影响。（3）药剂用量的增加和时间延长，对日本菟丝子生长指标抑制效果越好(P<0.05)。时间越久，不同处理间寄主恢复生长差异越大，15 mL/L处理对野蔷薇恢复生长指标有抑制作用。（4）药后30 d，寄生防治效果、生长防治效果、鲜质量和干质量防治效果在5，10 mL/L处理间无差异，15 mL/L处理鲜质量和干质量防治效果与5，10 mL/L处理差异较小，但15 mL/L处理显著降低寄主嫩茎和新叶的再生能力。结合防治效果、寄主恢复及安全性，推荐处理为10 mL/L。研究认为，基于“配量-时间”权衡策略，依据日本菟丝子危害程度和寄主生长要求，适当调整菟丝特处理，可为制定日本菟丝子精准防控方案提供借鉴。
Abstract:
A selective herbicide (Tusite AS) specifically targeting dodder was used as the test chemical,with four treatments (0, 5, 10 and 15 mL/L). At 10 d after treatment, the physiological responses of both Cuscuta japonica and its host, Rosa multiflora, were assessed. Key indicators included the activities of antioxidant enzymes (SOD, POD and CAT), the contents of osmotic adjustment substances (soluble sugars SS, soluble protein SP and starch ST), and the level of membrane lipid peroxidation MDA. The temporal dynamics of morphological change in both C. japonica and R. multiflora were evaluated at 10, 20, and 30 d after treatment. At the study endpoint (30 d), the control efficacy against C. japonica and the host plant injury index were determined. The phased evaluation was designed to analyze the combined effects of herbicide usage and post-application duration on the efficacy of C. japonica suppression and the physiological safety of R. multiflora.The results showed that: 1) The usage of Tusite significantly affected antioxidant enzyme activities, osmotic adjustment, and membrane damage-related parameters in both C. japonica and R. multiflora (P < 0.05). Specifically, SOD, POD, and CAT activities in C. japonica peaked at 10 mL/L Tusite. At 15 mL/L, C. japonica exhibited the lowest ST and SP contents, along with the highest MDA content. In contrast, 10 mL/L treatment could recover chlorophyll content in R. multiflora with minimal physiological damage. 2) The inhibition rate on haustorium diameter was highest at 10 d, while high inhibition rates for both haustorium number and vine stem diameter were observed at 20 d. By 30 d, the inhibition rates on haustorial and vine traits were lower than those recorded at 10 and 20 d. Throughout 10 to 30 d period, the negative effects of C. japonica parasitism on host plant height, crown width, leaf number, and young shoots were consistently alleviated and eventually reversed. 3) The inhibitory effects on the growth indices of C. japonica became more pronounced with usage increase and lasting (P < 0.05). The longer the period, the more distinct the differences in host recovery growth among treatments. Notably, 15 mL/L treatment exhibited inhibitory effects on the recovery growth indices of R. multiflora. 4) At 30 days after treatment, no significant differences were observed in parasitic control efficacy, growth control efficacy, fresh weight control efficacy, or dry weight control efficacy between 5,10 mL/L treatments (P > 0.05). Similarly, the fresh weight and dry weight control efficacy at 15 mL/L showed only minor differences compared with those at 5 mL/L and 10 mL/L (P > 0.05). However, 15 mL/L treatment significantly reduced the regenerative capacity of the host, particularly in terms of tender shoots and new leaves.In summary, considering control efficacy, host recovery, and plant safety, 10 mL/L was identified as the recommended treatment. Based on a "usage-time" trade-off strategy, the usage of Tusite AS may be appropriately adjusted according to the injury severity to parasitic plant and host protection requirements.
