“…Triacontanol is a plant hormone (Singh et al, 2012) that stimulates plant growth at very low concentration when exogenously applied to various plant species like groundnut (Verma et al, 2011), pigeonpea (Pujari et al, 1998), maize, rice and wheat . It has described that triacontanol enhanced the photosynthetic activity (Eriksen et al, 1981) mineral nutrients and water uptake (Ivanov and Angelov, 1997;Chen et al, 2003) and improved the quantity of many organic solutes in leaf tissues (Chen et al, 2003).…”

The present study elucidated the role of triacontanol in regulating seed germination and seedling vigour of four cucumber cultivars under salt stress (50 mM NaCl). Seeds were soaked in aerated solution of triacontanol @ 25 μM, 50 μM for 12 h prior to sowing and untreated seeds were used as control. Priming enhanced the emergence rate, uniformity and early growth of cucumber seedlings under normal and saline conditions. Though, plants exposed to salt stress and seeds not treated with triacontanol showed poor performance in growth, physiology and biochemical attributes. However, priming with 25 and 50 μM triacontanol was very effective in decreasing time to start emergence, improved final emergence, shoot/root lengths, seedling dry weight, gas exchange attributes, chlorophyll and proline contents under saline conditions. Nonetheless, maximum relief from salt stress in all attributes was observed at 50 μM triacontanol. In conclusion, triacontanol can be successfully employed to improve the germination capacity and stand establishment of cucumber under saline conditions by reducing the deleterious effects of salinity.

“…Foliar application of TRIA at 10 Á6 M significantly enhanced the crop herbage yield and the yield of essential oil in mint . Application of TRIA (at 10 Á6 M) also improved the values of primary and secondary fingers and rhizome yield per plant in turmeric and ginger (Singh 2008;Singh et al 2011). According to Nasir (2009), TRIA combined with N and P fertilizers (10 Á6.5 M of TRIA 'N 60 P 40 ) significantly increased the capsules per plant and seed yield of datura (Datura innoxia Mill.).…”

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.
