In vitro studies in Tagetes erecta (marigold) under auxins (IAA, NAA) and cytokinins (BAP, Kinetin) effect for callus formation by different explants

Abstract: Culture establishment depends on its physical and chemical environment. Different ex-plants of Tagetes erecta were subjected to different concentration of auxin (IAA, NAA) and cytokinin (BAP, Kinetin) to observe their response towards callus formation. Best callus formation was seen in loose cells of leaf blade as compared to arranged cells of nodes.

Marigold: From Mandap to Medicine and from Ornamentation to Remediation

Abstract: Importance of medicinal plants to health care has been great and herbal preparations are being produced at industrial scale particularly in developing countries. The plant products obtained have a long history of use in therapeutics, aromatherapy and food depending on the chemical constituents and their bioactivity. In the recent past, marigolds have received a great attention in scientific research, because of their multiple use and also the information available about their phytochemistry and bioactivity. Tagetes species commonly known as marigold is native to Mexico, being used for medicinal and ornamental purposes. The plant is useful due to its unique phytoconstituents for a range of diseases and disorders and is reportedly effective against piles, kidney troubles, muscular pain, ulcers and wound healing and the flowers are helpful in fever, stomach and liver complaints and also in eye diseases. In India, marigold is also extensively used on religious and social occasions such as in the beautification of mandaps and pooja places; offerings at temples; marriage decorations and landscape planning due to variable size and colour of its flower. Present review is an effort to bring together the different strategies developed for the growth and cultivation of marigold, its ecophysiological and remediation relevance under a variety of environmental conditions and possible allelopathic potential. It includes reports on pharmacological aspects like antibacterial, antifungal, larvicidal, hepatoprotective, insecticidal, mosquitocidal, nematicidal, wound healing, antioxidant, anticancer and antidiabetic properties/activity of Tagetes.

Effect of IBA and NAA and their combination on the shooting of stem cuttings of African marigold (Tagetes erecta L.) cv. Pusa Narangi Gainda

Abstract: The experiment was carried out in completely randomized design with three replications and the cuttings were planted on protray and placed at mist chamber and consist of three different concentrations of IBA (100, 200 and 300 ppm), NAA (100, 200 and 300ppm) and IBA+NAA (100+100, 200+200 and 300+300 ppm) along with control were treated for shooting in stem cuttings of marigold under Chhattisgarh plain region. The result revealed that growth regulators IBA and NAA had significantly effect on shooting performance of African marigold. The number of sprouts per cutting (7.55), average length of shoot (8.00 cm), number of leaves per cutting (163.44), fresh weight (1140.55 mg) and dry weight of shoot (159.00 mg) were recorded maximum in NAA 200 ppm at 35 days after planting of cuttings.

Effect of Plant Growth Regulators on in vitro propagation of Tagetes erecta Linn: Review

Abstract: The emerging new techniques in Plant Tissue Culture have led to the rapid growth of many plants of importance. Seasonal plants are even grown throughout the year under aseptic conditions. Plants of high medicinal value are cultivated in bulk and helps in increased amount for extraction of the necessary compounds. Tagetes erecta , a herbal medicinal plant, is propagated in vitro by applying the techniques of plant tissue culture. Till date, high growth of callus, shoot and root formation is observed in many of the research works. Also other species of the Tagetes family have shown good outcome in developing callus and root through tissue culture methods. Great work has been done in this field for the growth of the medicinal plant and many more are even expected to come. Applications of newer methods are being employed so as to minimize the cost with an increase in the resultant outcome.

Effect of plant growth regulators on in vitro propagation of tagetes erecta

Abstract: Tagetes erecta is a plant of great medicinal value and is in high commercial demand due to its various uses in religious purposes, as eatables, and is used for the treatment of headache and strengthening of the heart, treating wounds and prevent them from getting infected with bacteria and toxins. Young tender leaves of T.erecta were collected from plants grown in pots under adequate sunlight and rainfall.. Leaves were sterilised with 70% ethanol for 5 minutes and 0.02% Mercuric chloride for 3 minutes and inoculated in MS medium supplemented with Kn, IAA, NAA and 2,4-D in different combinations (0, 0.5, 2.5, 5.0, 10 mg/L). 50% callus formation are observed in 0.5 mg/L Kn from LT, 0.5 mg/L Kn + 2.5 mg/L IAA from LM, 0.5 mg/L Kn + 10.0 mg/L IAA from LM, 2.5 mg/L Kn + 0.5 mg/L IAA from LT, 5.0 mg/L Kn + 2.5 mg/L 2,4-D from LT and 10.0 mg/L Kn + 0.5 mg/L IAA from LM. 100% callus formation occurred in the combinations of 0.5 mg/L Kn + 5.0 mg/L 2,4-D from LB and LM, 2.5 mg/L Kn from LT and 5.0 mg/L Kn + 0.5 mg/L IAA from LT. Root formation was observed in the concentration of 2.5 mg/L Kn + 0.5 mg/L IAA from LT. Root formation was observed in low concentration of Kn in combination with a low concentration of cytokinin. Callus induction resulted in high concentration of Kn and cytokinin.. It has also been observed that the explants responded differently towards different growth regulators in varying concentrations. The best callus growth was found using the Kn and IAA as growth regulators within a short time period.

Effect of IBA and NAA and their combination on the rooting of stem cuttings of African marigold (Tagetes erecta L.) cv. Pusa Narangi Gainda

Abstract: The present investigation entitled “Effect of IBA and NAA and their combination on rooting in stem cuttings of African Marigold (Tagetes erecta L.) cv. Pusa Narangi Gainda” was conducted in the Horticultural Research cum Instructional Farm at Department of Floriculture and Landscape Architecture, College of Agriculture, Indira Gandhi Krishi Vishwavidyalya, Raipur (C. G.), season 2017. The experiment consisted of three different concentrations of IBA (100, 200 and 300 ppm), NAA (100, 200 and 300ppm) and IBA+NAA (100+100, 200+200 and 300+300 ppm) along with control which were treated for root initiation in stem cutting of marigold under Chhattisgarh plain region. The experiment was laid out in a Completely Randomized Design with three replications and the cuttings were planted on protray and placed in mist chamber. The result revealed that growth regulators IBA and NAA had significantly effect on rooting and shooting performance of marigold. The maximum survival percentage (88.33%) of rooted cuttings were recorded under 200 ppm IBA and 300 ppm IBA at 35 days after planting of cuttings. While the number of sprouts per cutting (7.55), average length of shoot (8.00 cm), number of leaves per cutting (163.44), fresh weight (1140.55 mg) and dry weight of shoot (159.00 mg) were recorded maximum in NAA 200 ppm at 35 days after planting of cuttings and the number of roots (93.44), fresh weight (404 mg) and dry weight of root (34.11 mg) were recorded maximum under 300 ppm IBA whereas, average length of roots (12.23 cm) were observed maximum under IBA 100 ppm.
