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.

Marigold is one of the commercially exploited flowering crops that belongs to the family Asteraceae. The production of economical yield and better quality of marigold flowers requires proper crop management techniques. Crop regulation is an important technique to make the marigold production profitable. This can be done by adopting application of plant growth regulators (PGRs). The present study was designed to investigate the effect of PGRs on flowering and antioxidant activity of two cultivars of African marigold (Tagetes erecta L.) viz. “Pusa Narangi Gainda” (hereinafter referred to as Narangi) and “Pusa Basanthi Gainda” (hereafter referred to as Basanthi). Plants were sprayed with abscisic acid (ABA), N-acetyl thiazolidine (NAD), gibberellic acid (GA3), salicylic acid (SA), indole-3-butyric acid (IBA) and oxalic acid (OA) at the concentrations of 100, 150, 250, 300 and 800 mg·L−1, each. Results revealed that the plants treated with 500–600 mg·L−1 IBA exhibited maximum increase in floral diameter (34–51%). The use of 500–550 mg·L−1 IBA exhibited maximal enhancement in flower fresh weight (21–92%). The exogenously applied OA significantly (p ≤ 0.05) improved flower dry weight, total phenolic contents, total flavonoid contents and reducing power ability of marigold plants. Overall, “Narangi” performed better than “Basanthi”, in terms of flowering and antioxidant activity. Conclusively, the results suggest that foliar application of PGRs favors flowering and antioxidant activity of African marigold.

A field experiment was conducted to study the response of nitrogen and GA3 on growth and flowering behavior of African marigold (Tagetes erecta L.) cv. Pusa Narangi Gainda at the Horticultural Research Farm, Department of Horticulture C. C. S. University Campus, Meerut (U.P.) in 2015. There were applied a total number of nine treatments and layout arranged in randomized block design (RBD) with three replications. Result indicated that soil application of nitrogen@100kg/ha with foliar application of GA3 @ 200ppm at 20 and 50 days after transplanting were found to be statistically significant and most beneficial in relation to plant height, primary branch, secondary branch, spread of plant, diameter in stem, flower diameter, number of flower per plant, fresh weight of flower per plant and yield of flower as compared to control and other treatments.

African marigold (Tagetes erecta L.) is one of the important commercial flower crop grown exclusively for their vibrant blooms. An experiment entitled “Effect of organic manures with foliar application of fish amino acid on growth and yield of African marigold (Tagetes erecta L.) was carried out in the department of Horticulture, Faculty of Agriculture, Annamalai University, Annamalainagar during (2018–2020). The twelve treatments includes organic inputs such as farmyard manure (25 t ha-1), vermicompost (5t ha-1), oilcake (2 t ha-1) along with foliar application of two levels of fish amino acid @ 2% and 4 % . The treatments were studied under randomized block design (RBD) with three replications. Among the twelve treatments, the performance of plants treated with (FYM @ 25t ha-1+ Vermicompost @ 5 t ha-1 + FAA @ 4%) resulted in superior plant height (63.42 cm), plant spread (54.31cm), number of primary branches (13.68), secondary branches (24.17) , number of leaves (154.86 ), dry matter production (118.23 g plant-1). Hence it is concluded that combined application of organic manures and fish amino acid had a good synergetic effect on vegetative growth of African marigold.

Great Utility

Biochemical markers are of great utility in screening for salt tolerance of crops. In common beans (Phaseolus vulgaris), lower levels of proline under stress have been associated with a better stress resistance of cultivars. In the present study, the responses to salinity have been analysed in six cultivars of common beans: four local landraces from Spain and two experimental lines from Cuba. Proline was used for ranking the relative tolerance of the cultivars, confirming a previous study which reported as more stress-tolerant two of the Spanish landraces. Total soluble sugars concentrations varied with treatments and between genotypes, but it was difficult to assess their role in stress tolerance of the analysed plants. Sodium concentration in leaves was the lowest in one of the two salt-resistant cultivars, and potassium did not vary or even increased under salt stress in all of them, except for the most susceptible one, where a drop of this cation was registered under 150 mM NaCl. Changes in malondialdehyde (MDA) contents did not indicate salt-induced membrane peroxidation resulting from secondary oxidative stress; consequently, accumulation of total phenolic compounds and flavonoids, as an antioxidant defence mechanism, was not detected. These results highlight the reliability of using proline as a biochemical marker of salt stress in common beans and the importance of the mechanism related to potassium transport to leaves in conferring stress tolerance to some common bean cultivars.
