transfer system the 1-octadecanol is converted to octadecanal. On the other hand, 1,12-dodecanediol goes through the phase transfer bromination and further reacted with 1-hydroxy-12-triphenylphosphonium bromide. Both the end products of the two compounds undergo Witting reaction to give the product. The resulted mixture is hydrogenated to give triacontanol. Physiological effects on some plant species Cacao Seedlings Cocoa seedlings (Theobroma cacao L.) shows a positive growth in terms of plant length and the leaf size when treated with triacontanol. In a study, the cocoa seedlings when receive an appropriate amount of triacontanol, led to increase in the leaf size, plant length, leaf number as well as the stem diameter of the cocoa plant. which is due to biosynthesis of secondary metabolites which alters the physiology and the biochemistry of the plants. Treating the cocoa plant with excess amount of triacontanol led to inhibition of plant growth and bearing of adverse effects on the plant physiology. The provision of triacontanol rapidly increase the morphogenetic response in the plant during the embryogenesis process. The enhanced response lead to increase in the cell division and cell growth by the growth regulators. Moreover, it also leads to increased shoots and roots of the plant. The whole process results from the formation of new growth and development proteins and new mRNA. Rhizophora apiculata (Mangrove) In the hypocotyl treatment of triacontanol in the mangrove plant resulted in increased root and shoot growth. The rise in the number of primary and secondary roots, the length of roots, height and the biomass resulted from triacontanol treatment. Moreover, the reduction of nitrate reductase as well as increase amount of chlorophylls in the photosystem 1 and 2 observed. However, the increase in the concentration of triacontanol resulted in the decrease of the plant growth. hence, the amount of the alcohol treatment is the driving force for the enhanced results. Cell cultures in vitro Triacontanol also increases the growth of a cell in vitro by increasing the cell number in the culture. It can be attributed to the increase protein formation and rapid cell division induced by triacontanol. The growth of cell culture in vitro has been done with various plant species to observe the effects of triacontanol. Similar effects of triacontanol can be seen with a variety of plants like rice, wheat, corn, maize, cucumber, and many more. References Fatty alcohols Plant hormones Primary alcohols Alkanols
