“…This leads to the disruption of energy flows in cells and finally represses the growth and development of plants. The growth-promoting effects of TRIA on various attributes especially those on fresh and dry weights, leaf-area and nodulation have been explored by Sharma and Dietz (2006) and Khan et al (2007) in various medicinal crops. A significant enhancement in TRIA values from treated plants could presumably be ascribed to the well-known effect of exogenously applied TRIA on elongation of internodes through cell division and cell extensibility .…”

“…TRIA is known as an antioxidizing agent because it can effectively inhibit both enzymatic and non-enzymatic peroxidative breakdown of lipids (Ramanarayan et al 2000). It is reported that TRIA after initial application elicits a metabolite or a secondary messenger, 9-β-L(+) adenosine, which rapidly induces a variety of physiological responses, and influences the activities of enzymes involved in carbohydrate metabolism (dry weight increase) (Khan et al 2007;Naeem et al 2009;Li et al 2016). Nitric oxide (NO) is a free radical involved in numerous and diverse physiological processes in plants (Lamattina et al 2003).…”

In this study, triacontanol (TRIA) and nitric oxide (NO) interaction on arsenic (As)-induced oxidative stress tolerance in coriander (Coriandrum sativum L.) plants was investigated. The results showed that As had a significant adverse effect on the plant's biomass. The seedlings pretreated with TRIA and NO significantly increased growth reduction induced by the metalloid. The obtained results indicated that the application of TRIA and sodium nitroprusside (SNP) generally reduced oxidative markers such as of electrolyte leakage percentage, malondialdehyde and H 2 O 2 contents under As toxicity, while application of As treatment without TRIA + SNP increased these oxidative parameters compared to the control. The non-enzymatic antioxidant contents such as total phenol, anthocyanin, carotenoid, ascorbic acid and reduced glutathione (GSH) were extracted and assayed from both control and treated plants. It was found that TRIA + SNP treatments have a profound effect on the antioxidant metabolism and caused an enhancement in non-enzymatic antioxidant potentials under As toxicity in coriander. Moreover, the results revealed a mutually amplifying reaction between TRIA and NO in reducing As-induced damages.ARTICLE HISTORY

“…The content of the pigments in TRIA-treated leaves could presumably be attributed to the increase in the number and size of chloroplasts as revealed by Ivanov and Angelov (1997), Chen et al (2003), and Muthuchelian et al (2003). Significant effects of TRIA on photosynthetic pigments were also reported in opium poppy and Japanese mint Sharma 1990, 1991), lemongrass (Misra and Srivastava 1991), opium poppy (Khan et al 2007), hyacinth bean ), artemisia , coriander , and coffee senna and mint .…”

“…In contrast, TRIA applied at 0.5 and 1.0 mg dm Á3 , reduced the leaf nitrate content in green gram (Kumaravelu et al 2000).

“…TRIA improved fresh and dry weights, leaf area, and the number and dry weight of nodules in case of hyacinth bean (Lablab purpureus L.) (Naeem and Khan 2005;Naeem et al 2010). Furthermore, the effect of foliar spray of GA 3 , TRIA, and that of their combination (GA 3 'TRIA) was found to be significant for plant height and dry weight of opium poppy (Khan et al 2007). Application of TRIA alone and in combination with potassium enhanced the plant height, fresh and dry weights and area per leaf of tomato ).…”

Triacontanol: a potent plant growth regulator in agriculture

Triacontanol (TRIA) is a natural plant growth regulator found in epicuticular waxes. It is used to enhance the crop production in millions of hectares, particularly in Asia. Quite a number of researchers have reported the TRIA-mediated improvement in growth, yield, photosynthesis, protein synthesis, uptake of water and nutrients, nitrogen-fixation, enzymes activities and contents of free amino acids, reducing sugars, soluble protein, and active constituents of essential oil in various crops. Expectedly, TRIA enhances the physiological efficiency of the cells and, thus, exploits the genetic potential of plant to a large extent. In fact, TRIA increased free amino acids, reducing sugars, and soluble protein of rice (Oryza sativa L.) and maize (Zea mays L.) within 5 min. TRIA elicited the appearance of L(')-adenosine within 1 min in the roots of plants, the shoots of which were sprayed with nanomolar concentrations of TRIA. TRIA and octacosanol (OCTA), the primary alcohols, are ubiquitous in the environment. OCTA was reported to inhibit the activity of TRIA in the seedlings of rice (Oryza sativa L.) at equimolar concentrations; and both TRIA and OCTA elicited a second messenger, known as OCTAM and triacontanol second messenger (TRIM), respectively. TRIA rapidly increases the ratio of L(')-to D(Á)-adenosine, probably at the tonoplast. However, it is to be resolved as to how TRIA elicits L(')-adenosine and what is the source of L(')-adenosine in plants. Based on known metabolic processes, de novo synthesis of L(')-adenosine is unlikely, because of the rapidity of the response. TRIA-mediated increase in dry matter production could influence the inter-relationship between primary and secondary metabolism, leading to increased biosynthesis of secondary products. Various studies present strong evidences that application of TRIA applied either to the root medium or to leaves enhanced the growth and yield of vegetables and other crops, including agronomic and horticultural crops as well as medicinal and aromatic crop plants under normal and adverse conditions. However, further investigations are required to elucidate the possible role of TRIA on plant growth regulation, physiological activities and secondary metabolite biosynthesis regarding medicinal and aromatic plants subjected to abiotic stress. The present review covers the pivotal role of TRIA in plant growth and development, its mode of action and its significance in improving the crop productivity and quality of agricultural crops.
