Forchlorfenuron Cytokinin is a phenylurea plant growth regulator with cytokinin activity

Forchlorfenuron is used as a plant growth regulator and has cytokinin activity, which can promote cell division, differentiation, organ formation, protein synthesis, improve photosynthesis, etc. Forchlorfenuron, a phenylurea plant growth regulator with cytokinin activity, is, however, 10-100 times more bioactive than 6-Benzylaminopurine. Widely used in agriculture, horticulture and fruit trees. It is able to affect plant bud development, accelerate cell mitosis, promote cell enlargement and differentiation, and prevent fruit and flower abscission, thus promoting plant growth, prematurity, delaying leaf senescence and increasing yield in later stages of the crop. The main features are: ① the function of promoting the growth of stems, leaves, roots and fruits, such as use in tobacco cultivation can increase the yield with hypertrophy of leaves. ② Promotes outcomes. Can increase the production of tomatoes (tomatoes), eggplants, apples and other fruits and vegetables. ③ Accelerated defoliation and defoliation. Grooming increases fruit yield, improves quality, and results in uniform fruit size. In the case of cotton and soybean, defoliation allows easy harvest. ④ Herbicides at high concentrations. ⑤ Others. Such as dry blight action on cotton, sugar beet and sugarcane increase sugar content, etc. Forchlorfenuron can affect the development of plant buds, accelerate cell mitosis, have a promoting effect on both lateral and longitudinal growth of organs, promote cell enlargement and differentiation, promote fruit expansion, prevent fruit and flower shedding, and increase the yield. Delay leaf senescence, retain green time long, strengthen chlorophyll synthesis, improve photosynthesis, and prompt deepening of leaf color to become green. Breaking the apical dominance, promoting lateral bud germination, being able to permeabilize the differentiation of buds, promoting lateral branch generation, increasing the number of branches, increasing the number of flowers, and improving pollen conception, thus increasing the number of fruits to improve yield. Improve crop quality and improve commodity. It induces monosexual fruiting, stimulates the enlargement of the ovary, prevents the falling of larch, promotes protein synthesis, improves sugar content, and so on. Forchlorfenuron is widely used in agriculture, horticulture and fruit trees. It is able to affect plant bud development, accelerate cell mitosis, promote cell enlargement and differentiation, and prevent fruit and flower abscission, thus promoting plant growth, prematurity, delaying leaf senescence and increasing yield in later stages of the crop. Forchlorfenuron has expanded fruits and promoted the effect of increase in yield, when applied in fruit trees, the increase in yield and its significant. The use of grape Forchlorfenuron in too high a concentration will easily decrease the soluble solids content, increase acidity, slow down coloration, and delay ripening. Soaking or spraying the fruit set 7-10 days after anthesis with gibberellin GA3 (10 mg / L) alone increased the yield but caused spikes hardening and uneven young fruit size, among others. Mixing Forchlorfenuron (5 mg / L) with gibberellin GA3 (10 mg / L) not only clearly improved the fruit set rate, but also promoted young fruit bulking and prevented side effects such as spike hardening and young fruit size misalignment.
