Carla (Momordica charantia L.) is a medicinal plant of the Cucurbitaceae family, which has antibacterial, anticancer, anti-tumor, hypoglycemic, hypertensive, and cholesterol properties. In this study, the effects of zinc oxide nanoparticles (ZnO-NPs) (20, 60, and 100 ppm), jasmonate (100, 250, and 500 μM), and chitosan (10, 50, and 100 μM) were measured on the growth and some physiological and biochemical parameters of Carla plant. The results revealed the highest shoot weight of plants at 250 μM jasmonate and 10 μM chitosan, while ZnO-NPs had no significant effect on shoot weight. ZnO-NPs (20–60 ppm) and jasmonate (100 and 200 µM) significantly increased chlorophyll a content, but chitosan showed no effect on chlorophyll a content. Secondary metabolites such as phenols, flavonoids, and carotenoids as well as carbohydrate and proline content were significantly increased by all elicitors in a dose-dependent manner. Antioxidant enzyme activity showed varied responses to different concentrations of elicitors. Jasmonate increased catalase (CAT), ascorbate peroxidase (APX), and guaiacol peroxidases (GPX) activity in a dose-dependent manner. Chitosan at all concentrations significantly increased CAT and APX enzymes activity, while at 100 μM concentration significantly increased GPX enzyme activity. ZnO-NPs did not affect GPX and AXP enzymes activity. Our findings confirmed for the first time that non-biological elicitors at specific levels have a significant growth promotion effect as well as increased production of valuable secondary metabolites in M. charantia.

非生物激发剂对药用植物苦瓜生理生化特性的影响。

卡拉(苦瓜L.)是葫芦科的药用植物,具有抗菌,抗癌,抗肿瘤,降血糖,高血压和胆固醇的特性。在这项研究中,测量了氧化锌纳米颗粒(ZnO-NPs)(20、60和100 ppm),茉莉酸酯(100、250和500μM)和壳聚糖(10、50和100μM)的影响。卡拉植物的生长和一些生理生化参数 结果显示,茉莉酸盐为250μM和壳聚糖为10μM时,植物的枝条重量最高,而ZnO-NPs对枝条重量没有明显影响。ZnO-NPs(20–60 ppm)和茉莉酸盐(100和200 µM)显着增加了叶绿素a的含量,但是壳聚糖对叶绿素a的含量没有影响。次生代谢产物,例如苯酚,类黄酮,所有激发子都以剂量依赖的方式显着增加了类胡萝卜素,碳水化合物和脯氨酸的含量。抗氧化酶活性显示出对不同浓度激发子的不同反应。茉莉酸酯以剂量依赖性方式增加过氧化氢酶(CAT),抗坏血酸过氧化物酶(APX)和愈创木酚过氧化物酶(GPX)活性。在所有浓度下,壳聚糖均显着提高了CAT和APX酶的活性,而在100μM浓度下,壳聚糖则显着提高了GPX酶的活性。ZnO-NPs不影响GPX和AXP酶的活性。我们的发现首次证实了特定水平的非生物激发子具有显着的促生长作用,并且增加了有价值的次生代谢产物的产生。抗氧化酶活性显示出对不同浓度激发子的不同反应。茉莉酸酯以剂量依赖性方式增加过氧化氢酶(CAT),抗坏血酸过氧化物酶(APX)和愈创木酚过氧化物酶(GPX)活性。在所有浓度下,壳聚糖均可显着提高CAT和APX酶的活性,而在100μM浓度下,可显着提高GPX酶的活性。ZnO-NPs不影响GPX和AXP酶的活性。我们的发现首次证实了特定水平的非生物激发子具有显着的促生长作用,并且增加了有价值的次生代谢产物的产生。抗氧化酶活性显示出对不同浓度激发子的不同反应。茉莉酸酯以剂量依赖性方式增加过氧化氢酶(CAT),抗坏血酸过氧化物酶(APX)和愈创木酚过氧化物酶(GPX)活性。在所有浓度下,壳聚糖均能显着提高CAT和APX酶的活性,而在100μM浓度下,壳聚糖则显着提高GPX酶的活性。ZnO-NPs不影响GPX和AXP酶的活性。我们的发现首次证实了特定水平的非生物激发子具有显着的促生长作用,并且增加了有价值的次生代谢产物的产生。在所有浓度下,壳聚糖均能显着提高CAT和APX酶的活性,而在100μM浓度下,壳聚糖则显着提高GPX酶的活性。ZnO-NPs不影响GPX和AXP酶的活性。我们的发现首次证实了特定水平的非生物激发子具有显着的促生长作用,并且增加了有价值的次生代谢产物的产生。在所有浓度下,壳聚糖均能显着提高CAT和APX酶的活性,而在100μM浓度下,壳聚糖则显着提高GPX酶的活性。ZnO-NPs不影响GPX和AXP酶的活性。我们的发现首次证实了特定水平的非生物激发子具有显着的促生长作用,并且增加了有价值的次生代谢产物的产生。M. charantia
