本论文以70%吡虫啉水分散粒剂为研究药剂,以番茄为研究试材,通过室内盆栽法研究了不同剂量的吡虫啉对番茄植株生长量的影响,以及对番茄体内过氧化氢酶(CAT)、超氧化物歧化酶(SOD)和番茄根系活力进行了测定.结果表明70%吡虫啉水分散粒剂分别以有效成分用量1.0、1.5、2.5、3.0 mg/株和5.0 mg/株5个剂量处理番茄幼苗,在处理后30 d测定番茄展开叶片数、株高、主根长、地上和地下部分鲜重,随着药剂浓度的增加,各测定指标呈现先升高后降低的变化趋势,其中以2.5 nag/株剂量影响最大,与清水对照比差异显著.测定不同浓度的吡虫啉处理番茄后30 d叶片及根系中CAT、SOD的活性和根系活力,结果表明不同剂量的吡虫啉均对番茄叶片和根系的CAT、SOD活性和根系活力有一定的影响,其效应并不是随药荆浓度的增加而增加,与清水对照比以2.5 mg/株剂量各生理指标活性增加最大,超过2.5 mg/株的剂量有下降趋势.
本論文以70%吡蟲啉水分散粒劑為研究藥劑,以番茄為研究試材,通過室內盆栽法研究瞭不同劑量的吡蟲啉對番茄植株生長量的影響,以及對番茄體內過氧化氫酶(CAT)、超氧化物歧化酶(SOD)和番茄根繫活力進行瞭測定.結果錶明70%吡蟲啉水分散粒劑分彆以有效成分用量1.0、1.5、2.5、3.0 mg/株和5.0 mg/株5箇劑量處理番茄幼苗,在處理後30 d測定番茄展開葉片數、株高、主根長、地上和地下部分鮮重,隨著藥劑濃度的增加,各測定指標呈現先升高後降低的變化趨勢,其中以2.5 nag/株劑量影響最大,與清水對照比差異顯著.測定不同濃度的吡蟲啉處理番茄後30 d葉片及根繫中CAT、SOD的活性和根繫活力,結果錶明不同劑量的吡蟲啉均對番茄葉片和根繫的CAT、SOD活性和根繫活力有一定的影響,其效應併不是隨藥荊濃度的增加而增加,與清水對照比以2.5 mg/株劑量各生理指標活性增加最大,超過2.5 mg/株的劑量有下降趨勢.

The physiology and biochemical characteristics and growth of tomatoes treated with different dosages of imidacloprid. Catalase (CAT), superoxide dismutase (SOD) and root activity of tomato were investigated. The number of leaves, plant height, root length, fresh weight of overground and underground parts were measured 30 days after treatments with 0, 1.0, 1.5, 2.5, 3.0, 5.0 mg per plant imidacloprid. The results showed that all of the values measured showed an increase at first and then a decrease, and at the dosage of 2.5 mg/plant, all of the values tested were the highest. The results indicated that imidacloprid could promote the growth of plants and the treatment of 2.5 mg imidacloprid per plant resulted in the most significant effects. The specific activities of CAT and SOD in tomato leaves and roots were also investigated in the laboratory. The results showed that activities of CAT and SOD in leaves and roots at all of the dosages treated were enhanced. The root activity of plants was also improved. The efficacy of 2.5 mg imidacloprid / plant was the highest among all of the dosages treated.
