“…Since these parameters reflect the overall growth of the plant, TRIA might help to boost up the overall growth, yield and quality of the plant. Additionally, the growth-promoting effect of TRIA on various attributes, including height and fresh and dry weights of plant, has earlier been reported by various workers regarding different medicinal plants (Misra and Srivastava 1991;Srivastava and Sharma 1991;Bhattacharya and Rao 1996;Kumaravelu et al 2000;Muthuchelian et al 2003;Giridhar et al 2005;Naeem and Khan 2005;Chaudhary et al 2006;Khan et al 2006Khan et al , 2007Khan et al , 2009Sharma et al 2006;Naeem et al 2009Naeem et al , 2010Aftab et al 2010;Idrees et al 2010).…”

Triacontanol (TRIA) has been realized as a potent plant growth promoting substance for a number of agricultural and horticultural crops. Out of a large number of essential oil bearing plants, mint (Mentha arvensis L.) constitutes the most important source of therapeutic agents used in the alternative systems of medicine. The mint plant has marvelous medicinal properties. In view of enhancing growth, yield and quality of this medicinally important plant, a pot experiment was conducted according to simple randomized block design. The experiment was aimed at studying the effect of four concentrations of TRIA (10 -0 , 10 -7 , 10 -6 and 10 -5 M) on the performance of mint with regard to growth and other physiological attributes, crop yield and quality attributes and the yield and contents of active constituents of the plant. The growth and other physiological parameters as well as yield and quality attributes were studied at 100 and 120 DAP. The foliar application of TRIA at 10 -6 M concentration significantly enhanced most of the growth and other physiological attributes, crop herbage yield and the yield and content of active constituents (menthol, L-methone, isomenthone and menthyl acetate) of mint at both the stages. However, the next higher concentration of TRIA (10 -5 M) exhibited slightly negative effect and did not further increase the values of the attributes studied, but it proved significantly better than the control. Application of TRIA significantly enhanced the yield and content of all the active constituents determined by GLC technique.

“…There are several reports which show that TRIA reduces the level of membrane damages due to its action as an antioxidant compound to inhibit peroxidation of membrane lipids (Ramanarayan et al 2000;Khan et al 2009). TRIA diminished lipid peroxidation probably through the stimulation of non-enzymatic (ASA and GSH) antioxidant machinery responsible for regulation of ROS balance during HM stress.…”

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

“…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). A significant improvement in leaf-nutrient content of tomato, opium poppy, artemisia, coriander, and ginger was observed by Khan et al (2006Khan et al ( , 2007Khan et al ( , 2009 suggested that a higher content of leaf-nutrients in TRIA treated plants could be attributed to the higher metabolic activity and increased dry matter production that might result in enhanced water and nutrient uptake from soil subsequently.…”

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.
