“…Naeem et al (2012) also reported that triacontanol possible role in regulating growth and metabolism of plants lies in the regulation of gene expression. According to Hangarter and Ries (1978) triacontanol potentially increases growth due to the increase in the number of cells in the plant. The activated genes in gene expression are due to the provision of triacontanol, the potential possibility to control the amount of cells from plant organs and organ size of the overall development of shoots and roots of the cacao seedlings.…”

The aim of this study was to evaluate the effect of plant growth regulator triacontanol to the growth of cacao seedings (Theobroma cacao L.). A completely randomized design was applied using non-factorial pattern on the treatment triacontanol growing regulator substance to level: 0.0 ml/L, 0.1 ml/L, 0.5 ml/L, 1.0 ml/L and 2.0 ml/L replicated 5 times. The result shows that the given of triacontanol significantly affected the growth of cacao seedings at the age of 14 weeks. The best triacontanol concentration was 1.0 ml/L, which was effectively able to increase the growth of cacao seedlings; high seedlings, number of leaves, lenght of leaves, and diameter of stems respectively reached 26.21%; 3.70%; 42.28%; and 10.42% higher than the control. Plant growth regulator triacontanol was efective to increase the growth of cacao seedlings.

“…The TRIA, applied at 10 mg L Á1 , increased the dry weight and leaf area of rice plants in nutrient cultures . Similarly, Hangarter et al (1978) found that TRIA, isolated from alfalfa or the one synthesized artificially (Analabs), were active at extremely low concentrations (23 nM). TRIA also promoted growth of tobacco callus at concentrations as low as 0.01 mg per Petri dish when applied to either roots or shoots .…”

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.

An Efficient Synthesis of 1-Triacontanol')Reduction of 12-dodecanolide (l), readily accessible from cyclododecanone, with diisobutylaluminium hydride afforded a 98 : 2 mixture of 12-hydroxydodecanaI(3) and 2-oxa-1 -cyclotridecanol (2). Its reaction with triphenyloctadecylphosphorane yielded 12-triaconten-1-01 (4), the catalytic hydrogenation of which gave a total yield of 68% of I-triacontanol(5) starting from cyclododecanone.Die Pflanzenwuchsstimulierende Wirkung des aus Luzerne isolierten I-Triacontanolsz) wird bereits durch geringste Verunreinigungen so stark beeintrachtigt3-6) oder gar inhibiert'), daJ3 fur seine praparative Gewinnung nur absolut einheitlich verlaufende Synthesen in Frage kornmen.
