Abstract

Triacontanol (TRIA) is a pivotal endogenous plant growth regulator with effective metabolic activator found in plant epicuticular waxes and in beewaxes as the palmitate ester. It is a non-toxic, pollution-free, low-cost, high-efficiency, broad-spectrum plant growth regulator.  It was found after a series of experiment that TRIA plays a significant role in promoting the growth and yields of corn, rice, wheat, tomato, carrot, cucumber, lettuce, soybean, potato, peanuts, chilli pepper, cotton and ornamental plants like rose etc. TRIA causes rapid responses in enhancing growth of the crop and the growth in rice, tomato and maize about 20% is enhanced by this treatment. The response is very rapid, an increased growth within 10 minutes. It is very much insoluble in water and is applied as foliage on the leaf at a very low concentration i.e.0.01mg/litre. However, further investigations are necessary to elucidate the possible role of TRIA on plant growth regulation, physio-biochemical as well as molecular activities and secondary metabolite biosynthesis in plants subjected to various biotic and abiotic stresses. The present review covers the pivotal role of TRIA in plant growth regulation, their mode of action and significance in improving the plant productivity and quality of both agricultural as well horticultural crops.
