Promote seed germination: Gibberellic Acid GA3+6-Benzylaminopurine (6-BA)
After soaking magnolia seeds in a mixed solution of 400mg/L Gibberellic Acid and 200mg/L 6-Benzylaminopurine for 48h, stratification for 56d under a humidity of 50% and a temperature of 7~10℃ can effectively break magnolia dormancy and increase seed germination rate.

Studies have shown that the use of 300 mg/L Indole-3-Butyric Acid (IBA) to treat lavender cuttings can quickly promote rooting, increase rooting rate, average root length, root number and root effect index‌.

Camellia, an evergreen shrub or small tree, can reach 3-4m in height. The flowers are solitary and opposite in the leaf axils or branch tops. The petals are nearly round. The variants have 50-60 double petals. The colors of the flowers are red, white, yellow, and purple.....

Auxins: Commonly used ones include 2,4-D, 2,4,5-TNaphthalene acetic acid (NAA), Indole-3-Acetic acid (IAA), etc. On citrus, 100-250 mg/kg2, 4-D treatment can effectively prevent the formation of the abscission layer at the fruit stem, keep the fruit stem bright green, prevent stem rot and black rot pathogens from invading the fruit, and greatly reduce rot .
