以野生茄托鲁巴姆(Solanum torvum)为砧木,以栽培品种西安绿茄(S.melongena)为接穗进行嫁接,测定不同施入频次多菌灵条件下嫁接茄子和自根茄子果实中的农药残留、生长发育状况和抗逆生理指标。结果表明,经过多菌灵施药1次、2次、3次处理后,嫁接茄果实中农药残留量比自根茄分别降低了12.7%～49.6%、11.4%～63.1%、13.5%～44.1%;嫁接茄株高、茎粗、植株鲜重和鲜果重相对于自根茄明显增加;嫁接茄根系活力比自根茄增加了6.8%～29.3%、8.7%～24.5%、11.1%～28.6%;嫁接茄叶片过氧化氢酶(CAT)活性、过氧化物酶(POD)活性、谷胱甘肽过氧化物酶(GSH-PX)活性相对于自根茄明显增加,而相对电导率比自根茄降低了16.3%～27.3%,19.7%～31.9%、20.5%～36.1%;嫁接茄丙二醛含量比自根茄降低了21.4%～31.6%、24.6%～37.9%、23.7%～39.0%。试验结果显示,施药2次和3次,各指标变化相对于施药1次明显。因此,在多菌灵胁迫下,嫁接茄子果实中的农药残留降低,植株长势明显增强,有关酶的代谢活性显著提高,从而缓解了多菌灵胁迫对茄子造成的危害。
The rootstock of Solanum torvum was used as the rootstock, and the cultivar S. melongena was used as the scion for grafting. The pesticides in grafted eggplant and self-rooted eggplant fruit under different application frequency of carbendazim were determined. Residue, growth and development and anti-stress physiological indicators. The results showed that pesticide residues in grafted eggplant fruits decreased by 12.7% -49.6%, 11.4% -63.1% and 13.5% -44.1, respectively, after being treated with carbendazim once, twice or three times. The root activity of grafted eggplant increased by 6.8% -29.3%, 8.7% -24.5%, and 11.1% -28.6% compared with that of the original rooted tomato %. CAT activity, peroxidase (POD) activity and glutathione peroxidase (GSH-PX) activity of grafted tomato leaves were significantly increased compared with those of self-rooted tomato, while relative conductivity Compared with the rooted tomato, the content of MDA decreased by 21.4% ~ 31.6%, 24.6% ~ 37.9%, 23.7% ~ 20% 39.0%. Test results show that spraying 2 times and 3 times, the changes of each index relative to the application of a significant. Therefore, under the carbendazim stress, the pesticide residues in the grafted eggplant fruit decreased, the plant growth significantly increased, the metabolic activity of the enzyme significantly increased, thus alleviating the harm caused by the carbendazim stress on the eggplant.
