(2014) suggested that naphthalene acetic acid can be used for enhancement of growth and yield of cereals. Use and regulation. NAA/BAP ≈ 1), callus growth was enhanced. Table 1. ABSTRACT: In order to evaluation the effects on growth and yield of tomato plants in a soil sample, tested in a completely randomized design with three replications. Licensed Under Creative Commons Attribution CC BY Increase in plant height with the application of NAA was also reported by Lakshmamma and Subba Rao (1996) in wheat which is consistent with the results of our present study. This paper concerns the studies towards membrane-damage effect of two auxins: indole-3-acetic acid - IAA and 1-naphthaleneacetic acid - NAA on plant (Arabidopsis thaliana) and animal (rat liver) model membranes. Additionally, several other naturraly occurring indole derivatives are reported to express auxin activity, including indole-3- ethanol, indole-3-acetaldehyde, and indole-3-acetonitrile. The research on the effect of plant growth regulators on algae lags far behind work with other terrestrial plants. The research was carried out … In general, when ever NAA and BAP were in balance (i.e. Plant Tiss. It is applied after blossom fertilization. Various concentrations (0.05-0.5mgL-1) of NAA were added to the MS medium, 1/2-strength and 1/4-strength MS medium to … The plants were harvested 85-90 days after sowing in the first week of May, 2006. Distortion and killing of organs. ppm + NAA 250 ppm treated cuttings resulted in maximum number of roots (12.87) (T 6). The treatment of foliar spray of NAA (25 and 50 ppm) and GA3 (150 and 250 ppm) was given at thirty and forty days after transplanting. 2005;15(2):121-126. mg) (Davies and Hobes, 1981). 15 ppm (15 mg/l) CPPU showed the best effects on the fruit size and biochemical quality of the wax apple. NAA has been shown to greatly increase cellulose fiber formation in plants. Natural and Synthetic Auxin: The main auxin in plants is indole-3-acetic acid (IAA Fig. Effect of NAA on fruit set and fruit retention percentage of mango cv. Hormonal Concentrations Used . Minimum plant height was recorded on T 9 (control treatment). plants) was established by Das and Rout (2002) [11] in the presence of benzyl amino purine (BAP), IAA, α-naphthalene acetic acid (NAA), kinetin (Kn) and gibberellic acid (GA3) fortified media at various stages and effect of acetylsalicylic acid and ammonium Komariah et al. The foregoing auxins are plant growth regulators widely used in agriculture to control the quality of the crop. significant effect of growth regulators on growth parameters at T 2 (GA 3 @ 50 ppm at 40 DAS) where maximum plant height (107.97cm) was recorded, followed by T 5 (NAA @ 50 ppm at 40 DAS) plant height (104.31cm). Effect of foliar spray of plant growth regulators viz., Gibberellic acid (GA3) and Naphthalene Acetic Acid (NAA) on vegetative, flowering, quality and yield parameters of three carnation varieties under naturally ventilated poly house in Allahabad agroclimatic condition was investigated. KALIPATTI @inproceedings{Garhwal2015EFFECTOS, title={EFFECT OF SADH, NAA AND GA3 ON GROWTH, YIELD AND … CCC and GA application gave quite beneficial effects on these parameters. Similar result was reported by Rani et al., (2013), These chemicals had no adverse effect on the growth and flowering of French marigold. Among the growth regulators GA 3 and NAA exhibited beneficial effect in several crops including cauliflower. Tas-e-Ganeshand Kismis chorny Results showed that NAA had positive effect on rooting at the concentration of 200 mg/l compared to other concentrations at 30 days after planting (DAP). (2004) [22] for optimum embryogenesis. Forsberg] CV. Plant hormones and growth regulators are chemicals that affect: Flowering. This is consistent with the effect of NAA on leaf colour variants of … NAA is a synthetic plant hormone in the auxin family and is an ingredient in many commercial plant rooting horticultural products; it is a rooting agent and used for the vegetative propagation of plants from stem and leaf cuttings. Root growth. The effect of exogenously applied natural [indole-3-acetic acid (IAA), phenylacetic acid (PAA), indole-3-butyric acid (IBA)] and synthetic [1-naphthaleneacetic acid (NAA)] auxins on the growth and metabolism of green microalga Chlorella vulgaris was examined. The effect of NAA on plant growth is greatly dependent on the time of admission and concentration. Prevention of leafing, leaf fall or both. Combined effect of GA3 and NAA produced the maximum plant succession percentage (100), plant height (71.33 cm), number of leaves plant-1(36.89) and plant diameter at 67 DAT from the treatment G2N2 that means at treatment T5. GA at 400 ppm and CCC at 600 ppm recorded the highest flower yield per plant (127.71 g) and number of flowers per plant (78.83), respectively. It is important to understand how these factors affect plant growth and development. Petkova S, Popova N, Angelova Y, Stefanov B, Iliev L, Popov M. Inhibitory effect of some plant growth regulators and chlorosulfuron on growth, protein composition and proteolytic activity of maize seedlings. week after the spray was given to the plants. Effects of different plant growth regulators on root formation The plant growth regulator NAA was used to promote root formation. Role of NAA on growth of tomato NAA is commonly used in horticulture crops. Application of GA3 also had significant effect on … With a basic understanding of these factors, you may be able to manipulate plants to meet your needs, whether for increased leaf, flower, or fruit production. In some algal species, auxin stimu- Raoofi et al. EFFECT OF SADH, NAA AND GA3 ON GROWTH, YIELD AND QUALITY OF SAPOTA [Manilkara achras (Mill.) Prevention or promotion of stem elongation. NAA can increase fruit setting ratio, prevent fruit dropping, promote flower sex ratio. The effect of plant growth regulator (NAA) on the yield potential of coarse rice was evaluated during rice growing season of 2004 and 2005 at the Postgraduate Agriculture Research Farm, Gomal University, Dera Ismail Khan, Pakistan. The higher concentrations of NAA inhibit growth and exert toxic effects on the plants so, optimum concentrations are required for find out to beneficial effects of NAA. Interaction effect of types of cutting and plant growth regulators showed significant effect, where maximum number of roots per cutting (19.35) observed in the terminal cuttings treated with IBA 500 ppm + NAA 250 ppm (C 3 … In majority of fruit plants fruit drop is controlled by spraying of NAA in different fruit crops in different concentration. Urea levels at zero, 50, 100, 150 and 200 mg per kg of soil was used. Gibberelic acid (GA Aging. Hormones are produced naturally by plants, while plant growth regulators are applied to plants by humans. had highest significant increase in grain yield followed by T2 (GA3 45 g), T1 (GA3 30 g), T5 (NAA 200 g), T3 (NAA 100 g), T27 (Urea 2 g + C.C.) treated with 50 or 100 mg IBA per litre or the mixture of IBA+NAA was detrimental to 150 mg per litre reached 83 to 90 per cent the rooting of grape vine cuttings. In most of the plants, the formation of roots can be promoted by auxins while cytokinins promote the shoots formation in vitro. Micropropagation of Aloe barbadensis Mill. It produces significant effect on the development of pointed ends for the root system. paniculata shoot cuttings. It plays an important role in flowering, fruit setting, ripening and physiochemical changes during storage of tomato. Traditionally, plant hormones and synthetic plant growth regulators are used as valuable research tools to elucidate physiological responses of plants or to probe biochemical control mechanisms.
