Thidiazuron, with the CAS number 51707-55-2, is a high - quality product offered at a competitive price. Its chemical name is 1 - phenyl - 3 - (1,2,3 - thiadiazol - 5 - yl)urea. Thidiazuron is a white to off - white crystalline powder. It has a molecular formula of C₉H₈N₄OS and a molecular weight of 220.25 g/mol. The melting point of Thidiazuron is in the range of 210 - 212°C. It is sparingly soluble in water but soluble in organic solvents such as acetone, ethanol, and dimethyl sulfoxide (DMSO). This product is known for its high purity, which ensures reliable results in various applications.
Thidiazuron is widely used in the agricultural and horticultural fields. In agriculture, it acts as a plant growth regulator. It can promote cell division, differentiation, and elongation in plants. For example, it is used to enhance the growth of shoots and roots in tissue culture of various crops. In tissue culture, it can stimulate the formation of adventitious buds, making it an essential component for micropropagation of plants like bananas, orchids, and many other ornamental and commercial crops. It also has the ability to induce leaf abscission in some plants, which is useful for facilitating mechanical harvesting in certain fruit - bearing plants. In horticulture, Thidiazuron can be used to improve the quality and quantity of flowers. It can increase flower bud formation, flower size, and flower longevity, making it popular among flower growers.
When using Thidiazuron, it is important to follow the recommended dosage and application methods. For tissue culture, it is usually added to the culture medium at a concentration ranging from 0.1 - 10 mg/L, depending on the plant species. The medium should be autoclaved or filter - sterilized after adding Thidiazuron to ensure its stability and effectiveness. When using it for foliar spray in the field, the recommended concentration is typically between 1 - 10 ppm. It is advisable to dissolve Thidiazuron in a small amount of organic solvent first, such as DMSO or ethanol, and then dilute it with water before spraying. The spraying should be done in the early morning or late evening to avoid high - temperature stress on the plants. Also, proper safety measures should be taken during handling, such as wearing gloves and goggles.
In a commercial banana tissue culture laboratory, Thidiazuron was added to the culture medium at a concentration of 1 mg/L. The result was a significant increase in the number of adventitious buds formed. Compared to the control group without Thidiazuron, the treated group had a 30% higher rate of bud formation. After transplanting the plantlets to the field, they showed better growth and higher survival rates. In an orchid nursery, a foliar spray of Thidiazuron at a concentration of 5 ppm was applied during the flower - bud differentiation stage. The orchids produced larger and more vibrant flowers with a 20% increase in flower diameter and a longer blooming period of up to 7 days compared to the untreated orchids. Another case is in a peach orchard. A pre - harvest application of Thidiazuron at a concentration of 8 ppm induced uniform leaf abscission, which facilitated mechanical harvesting. The harvesting efficiency increased by 25%, and there was a reduction in fruit damage during the harvesting process.
