1-Triacontanol (n-triacontanol) is a fatty alcohol of the general formula C30H62O, also known as melissyl alcohol or myricyl alcohol. It is found in plant cuticle waxes and in beeswax. Triacontanol is a growth stimulant for many plants, most notably roses, in which it rapidly increases the number of basal breaks. 1-Triacontanol is a natural plant growth regulator. It has been widely used to enhance the yield of various crops around the world, mainly in Asia. Triacontanol has been reported to increase the growth of plants by enhancing the rates of photosynthesis, protein biosynthesis, the transport of nutrients in a plant and enzyme activity, reducing complex carbohydrates among many other purposes. The fatty alcohol appears to increase the physiological efficiency of plant cells and boost the potential of the cells responsible for the growth and maturity of a plant. History Triacontanol was first isolated in 1933 from alfalfa wax. It was identified as a saturated straight chain primary alcohol. Triacontanol is found in various plant species as a minor component of the epicuticular wax. In wheat, triacontanol is about 3-4% of the leaf wax.. The effects of triacontanol may also be seen when a chopped alfafa plant is placed in close proximity to the seedlings and various crop seeds. A substantial increase in yield and growth has been seen in different plants, such as cucumber, tomatoes, wheat, maize, lettuce, and rice. Characteristics Triacontanol does not react the same way in all plant species. The effects of triacontanol various in terms of photosynthesis and the yield manipulation in plant species. The effects on C-3 plants and C-4 plants. In tomato plant (C-3 plant), the treatment of triacontanol increases the dry leaf weight and inhibited the photosynthesis by 27% in dry leaves, whereas in the maize plants no change in photosynthesis occurs whether treated by triacontanol or not. Although, the basic effect of treating seedlings of various plant species is an increase in plant growth, photosynthesis and the yield of the crops, the effects of triacontanol are not the same in every plant species. Some exhibit these symptoms while some show no response to the treatment to triacontanol. Different studies reveal that the effects of triacontanol differs with the amounts of the triacontanol used to treat the plant. A much higher dose of triacontanol could also have adverse effects on the growth of a plant. Triacontanol has been reported to increase productivity of
