“…TRIA has been reported to enhance photosynthesis and water and mineral nutrients' uptake, regulate activities of various enzymes and increase the level of various organic compounds in leaf tissues (Ries & Houtz 1983;Ries 1991;Naeem et al 2009Naeem et al , 2010. 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).…”

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

“…Several efforts have been made to elucidate the mechanism of TRIA action Ries 1991;Ries et al 1993). Assumption of a cascade effect led to the identification of 9-b-L (')-adenosine as a second messenger of TRIA (Ries 1991;Ries et al 1993). TRIA rapidly elicits the second messenger (TRIM) in rice (Oryza sativa L.), which at nanomolar concentrations causes the plants to respond in a manner similar to TRIA (Ries 1991).…”

“…TRIA application increased the plant dry weight, protein, and chlorophyll contents and net photosynthetic rate in rice (Oryza sativa L.) (Chen et al 2002). Similarly, exogenous application of TRIA showed positive effect on growth, chlorophyll content, efficiency of photosystem-II (PS-II) and gas exchange characteristics in the seedlings of rice (Muthuchelian et al 1995;Kumaravelu et al 2000), maize (Ries 1991), and wheat (Ries 1991). Increase in plant growth could mainly be due to an abrupt TRIA-induced increase in photosynthesis as TRIA has been reported to be involved in the up-regulation of many genes involved in the photosynthetic process (Chen et al 2002(Chen et al , 2003.…”

Muthuchelian et al (1997Muthuchelian et al ( , 2003 investigated the significant effect of TRIA on acid mist-treated Erythrina variegata L. seedlings with particular emphasis on growth, photosynthetic pigments, ribulose-1,5-bisphosphate (RuBPC), and photosynthetic activity.…”

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.

The arrival of new plant growth regulators on the market in the early 1990s, especially synthetic ones, is in a static state. Many growth regulators continue to be used experimentally, but the transition to approved usage is being delayed for several reasons. On the financial side, a number of mergers, buy‐outs, and other dispositions of chemical companies has led to a decrease in the number of commercial compounds available. Moreover, the cost of registration has prompted some producers to withdraw chemicals from the market. Some older plant growth regulators have undergone several trade name changes, adding confusion to the field. The ideal plant growth regulator should leave no harmful persistent residue in a finished product or crop and the paradigm compounds are ones that have high specific activity, are target specific, and are environmentally biodegradable. The most acceptable growth regulators appear to be those compounds that already occur in nature and elicit certain desirable responses in economic crops.
