Abstract:The role of organic farming cannot be neglected from view of quality crop production as the running unhealthy strategies commonly employed in agriculture are destabilizing farming systems 1. Now-a-days, the goal to access valuable crop yield is accomplished by practicing non-destructive and economical agricultural practices which aim to ensure crop productivity. In recent years, it is a common practice to implement plant growth regulating compounds which might include growth hormones, inorganic fertilization a… Show more
“…3, depicts that all PLEs enhanced TPC as compared to control and previous findings also support these results that phenolic contents were significantly enhanced in response of Verbesina encelioides application allelopathic in radish [72], sweet basil [73]. Lentil plant [74] and in Coriandrum sativum under the exogenous applications of plant growth regulators also revealed an enhancing effect on TPC [75].Figure 3Variation in total phenolic contents (TPC) (mg GAE/100 g FW) in response of foliar application of plant growth regulators (explanations as given in Fig. 1).…”
The present study was aimed to appraise the variations in biochemical, antioxidant and nutritional attributes of radish (Raphanus sativus L.) under foliar application of plant leaf aqueous extracts i.e., mulberry leaf extract (MLE), brassica leaf extract (BLE), sorghum leaf extract (SLE) and moringa leaf extract (MoLE) as natural growth regulators. Samples were collected after three sprays of extracts and analyzed. Total phenolic constituents were determined using Folin-Ciocalteu reagent method, whereas antioxidant potential was evaluated by 1,1 diphenyl-2-picrylhydrazyl radical radical scavenging and reducing power assays. Results revealed that application of MLE, BLE, SLE, and MoLE not only improved growth, but also enhanced biochemical and antioxidant activities. Foliar spray of MoLE furnished relatively three folds higher amounts of extractable bioactive compounds (37.65 ± 0.94%), phenolic constituents (54.51-182.71 mg GAE/g f.w). The radical scavenging capacity (RSC) and reducing potential were also enhanced considerably. Furthermore, the moisture, dietary fiber, crude protein, and carotenoids were also enhanced in response of foliar spray of plant extracts. From results, it is concluded that plant extracts are effective sources of natural growth regulars and might be useful for the production of vegetables with improved nutritional value and antioxidant activity.

“…This might possibly be due to the minerals, β-carotene, and vitamins included in moringa leaves, which may cause plants to enhance their phenolic metabolism. [91]. Dry Azolla application significantly increased total phenols in chamomile [92].…”
Increased demand for quinoa as a functional food has resulted in more quinoa-growing areas and initiatives to increase grain production, particularly in organic agriculture. Quinoa seeds are a superfood with incredible nutritional benefits. They are abundant in secondary metabolites with significant medicinal activity. This report was consequently performed to investigate whether Azolla fliculoides (AE) or moringa leaf extract (MLE) foliar spray can be supplemented as organic extracts to enhance quinoa growth and productivity under organic farming. Three quinoa cultivars, KVL–SRA2 (C1), Chipaya (C2), and Q–37 (C3), were grown organically and subjected to foliar spraying with AE or MLE at a 20% ratio, as well as their combination (AE+MLE). Plant performance of the three cultivars was significantly enhanced by MLE or AE applications as compared with control plants. The highest outputs were obtained by AE+MLE treatment, which significantly increased the seed yield by about 29% as compared with untreated plants. Seed quality exhibited a marked increase in response to AE+MLE that was superior in this regard as it showed higher protein, carbohydrates, saponine, tannins, phenolics, and flavonoids content. The C3-cultivar demonstrated the highest productivity, saponine, and flavonoids levels as compared to the other cultivars. Overall, the current study indicated that foliar spray with AE+MLE could enhance growth and productivity as well as quality and pharmaceutical active ingredients of quinoa cultivars grown under farming conditions.
“…However, GB treatment noticeably enhanced phenolics more than unstressed or stressed plants. Moreover, the carotenoids detected in marigold plants were enhanced [38]. Glycinebetaine foliar application can enhance abiotic constraint tolerance of several plants and subsequently improve growth and productivity, so if applied to photosynthetic organs, it is well absorbed by foliar tissues localized in cytosol and translocate to chloroplasts [39] and also taken up via roots [40].…”
Tagetes genus of Composite family consider one of the most favorite floriculture plant. Therefore, of particular interest examine the salt tolerance of this bedding and coloring agent plant. In this research, was report the role of glycinebetaine (GB) in attenuating the adverse impacts of salt stress in African marigold plant, along with their anti-oxidative capacities and biochemical attributes. The salt stressed African marigold (100 and 150 mM NaCl) was treated with GB at 200 mM, beside untreated control plants. According to the obtained results, the growth characters were negatively in salt stressed plants but a mitigate impact of GB were observed in this respect. Obviously, the morphological as well as some physiological characters were reduced with salinity treatments while GB treatment reverses these effects. Overall, the alleviate impact of GB on the negative impact of salt stress was enhanced through improving total phenolic and antioxidant enzyme activity. Further, it is concluded that GB concentration induces the activities of antioxidative enzymes which scavenged ROS increased under saline conditions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
