摘要

摘要: 为明确植物生长调节剂苯肽胺酸对作物的生物学效应，以辣椒为供试植物，芸苔素内酯为对照药剂，研究了苯肽胺酸不同浓度处理对辣椒植株抗逆生理指标及产量的影响。结果表明：200.0 mg/L质量浓度的苯肽胺酸可显著提高辣椒植株的抗逆性，与空白对照相比，辣椒叶片中类黄酮、总酚以及游离脯氨酸含量分别提高了10.06%~21.19%、7.42%~16.95%以及8.46%~241.26%；丙二醛含量下降了28.58%~52.79%；超氧化物歧化酶（SOD）、过氧化物酶（POD）和过氧化氢酶（CAT）活性分别提高了2.31%~9.00%、4.20%~471.72%和34.98%~121.19%。200.0 mg/L的苯肽胺酸处理具有明显增产效果，与空白对照相比，产量增加了13.91%。研究表明，苯肽胺酸的生物学效应与芸苔素内酯类似，可诱导辣椒抗逆性增强，且具有一定增产效应。

Abstract: In order to determine the biological function of phthalanilic acid, the effects of phthalanilic acid (266.7, 200.0 and 133.3 mg/L) on the stress-resistance physiological indexes and the yield of pepper (Capsicum annuum L.) were investigated, with brassinolides as the control. The results showed that phthalanilic acid could significantly regulate the stress resistance of pepper plants. If the concentration is 200.0 mg/L, compared with the blank control, the contents of flavonoids, total phenolics and free proline in the leaves of pepper were increased by 10.06%-21.19%, 7.42%-16.95% and 241.26%-8.46% respectively, and the content of MDA was decreased by 28.58%-52.79%. Furthermore, the activities of Superoxide dismutase (SOD), Peroxidase (POD) and Catalase (CAT) were increased by 2.31%-9.00%, 4.20%-471.72% and 34.98%-121.19%, respectively. Phthalanilic acid treatment (200.0 mg/L) could also significantly increase the yield of pepper by 13.91%, compared with the blank control. Thus, it demonstrated that phthalanilic acid could induce the stress-resistance of pepper plants and increase the yield of pepper, which is similar as brassinolides.
