Abstract

The purpose of this study was to evaluate some elements of physiology and biochemistry in Nepeta racemosa Lam. in the pedo-climatic conditions of the Moldavian forest steppe. The parameters were quantified under conditions of differentiated fertilisation with three foliar products (KSC 1, KSC 2, and Corona K). Biochemical analysis by GC/MS revealed the highest concentration of the following components: nepetallic acid (Untreat - 54.33%, KSC 1 - 55.50%, KSC 2 - 56.90%, Corona K - 53.77), eucalyptol (Untreat . 9.87%, KSC 1 - 10.70%, KSC 2- 12.80%, Corona K - 10.78%), 3-hydroxy-(4S, 4aS, 7S, 7aS)-dihydronepetalactone (Untreat - 5.87%, KSC 1 - 5.37%, KSC 2 - 4.87, Corona K - 3.67%), and (4aS, 7S, 7aS)-trans, cis-nepetalactone (Untreat - 4.30%, KSC 1 - 5.00%, KSC 2 - 4.20%, Corona K - 5.23%). Polyphenols were present in large quantities in the Corona K variant, with 33.1 mg GA/g dw at the first harvest and 27.88 mg GA/g dw at the second harvest. The highest concentration of flavonoids was identified in the Corona K variant (26.34 mg QE/g dw - first harvest and 56.77 mg QE/g dw - second harvest). The antioxidant activity was between 14.76 and 38.54% at the first harvest, and from 12.18 to 22.95% at the second harvest. Chlorophyll pigments ranged from 13.12-17.68 μg/ml-1 for chlorophyll a, 5.43-9.66 μg/ml-1 for chlorophyll b, and 2.07-3.34 μg/ml-1 for carotenoids. The highest grass production per m2 was achieved in the version fertilised with KSC 1 for both crops, with 986.66 g/m2 for the first harvest and 861.33 g/m2 for the second. Iridoids are a class of substances that are commonly used for pesticide role. The study aims to highlight these substances and determine whether differentiated fertilization influences. The presented data confirm the results in the literature for polyphenols and flavonoids, but also present chemotypic novelties in terms of chemical composition and represent a direction to follow for future research.

叶面施肥对总状荆芥生理生化特性的影响。

本研究的目的是对总状荆芥的一些生理生化因素进行研究。在摩尔多瓦森林草原的土壤气候条件下。用三种叶面产物(KSC 1、KSC 2和Corona K)进行分化施肥，定量测定了这些参数。GC/MS生化分析显示，其中nepetalic酸(Untreat - 54.33%， KSC 1 - 55.50%， KSC 2 - 56.90%， Corona K - 53.77%)和桉树醇(Untreat - 53.77%)的含量最高。9.87%， ksc1 - 10.70%， ksc2 - 12.80%， Corona K - 10.78%)， 3-羟基-(4S, 4aS, 7S, 7aS)-二氢内酯(Untreat - 5.87%， ksc1 - 5.37%， ksc2 - 4.87, Corona K - 3.67%)和(4aS, 7S, 7aS)-反式，顺式内酯(Untreat - 4.30%， ksc1 - 5.00%， ksc2 - 4.20%， Corona K - 5.23%)。多酚在科罗娜K变异中大量存在，第一次收获时为33.1 mg GA/g dw，第二次收获时为27.88 mg GA/g dw。在科罗娜K变异株中，黄酮类化合物含量最高(第一次收获26.34 mg QE/g dw，第二次收获56.77 mg QE/g dw)。第一次收获抗氧化活性为14.76 ~ 38.54%，第二次收获抗氧化活性为12.18% ~ 22.95%。叶绿素a含量为13.12 ~ 17.68 μg/ml-1，叶绿素b含量为5.43 ~ 9.66 μg/ml-1，类胡萝卜素含量为2.07 ~ 3.34 μg/ml-1。两种作物在施用KSC 1的版本中每平方米草产量最高，第一次收获986.66 g/m2，第二次收获861.33 g/m2。环烯醚萜是一类常用的农药物质。该研究旨在突出这些物质，并确定分化受精是否会影响。这些数据证实了文献中对多酚类和黄酮类化合物的研究结果，但也在化学成分方面呈现出化学型的新颖性，并为未来的研究指明了方向。
