What is the effect of triacontanol on plants?

Triacontanol, also known as melisitol, is a Plant Growth Regulator commonly used in agriculture, like brassinolide, chlormequat, and sodium nitrophenolate. It is effective for rice, wheat, cotton, soybeans, and corn, peanuts and other crops have the effect of increasing production. In 1974, Khanma et al. identified linear fatty alcohol - 1-triacontanol [OH3(CH2)28CH2OH] from green tea, which was later called "triacontanol" and can be extracted from tea by-products. This substance can be used as a foliar nutritional fertilizer for crops. It can be sprayed at a concentration of 0.5ppm at the one-leaf stage of tea buds, which has a yield increase effect of about 20%. It can also increase the proportion of normal buds and leaves and increase the content of Amino Acids, tea polyphenols and water extracts. .

Triacontanol belongs to Cytokinins,has a variety of physiological functions and can affect plant growth, differentiation and development. The main performance is: it can enhance the activity of enzymes, promote seed germination, and increase the germination rate; enhance photosynthetic intensity, increase chlorophyll content, and increase the accumulation of dry matter; promote the absorption of mineral elements by crops, increase protein and sugar content, and improve product quality, etc. It can also promote the growth of roots, leaves and flower bud differentiation of crops; increase tillers, promote early maturity, preserve flowers and fruits, and improve the fruit setting rate; promote water absorption of crops, reduce evaporation, and increase the drought resistance of crops. Triacontanol is suitable for the cultivation of seaweeds such as kelp and seaweed and for increasing the yield of peanuts, corn, wheat, tobacco and other crops.
