Yang and Lu Receive U.S. Patent No. 10,028,505

Alexandrian laurel (Danae Racemosa L.) is an evergreen shrub in high demand. The seed germination of Alexandrian laurel often takes up to 12 to 18 months with a germination rate of only about 20%. Due to its slow-growth rate, it typically takes up to six years to produce a saleable one-gallon size plant. Dr. Yang and Ms. Zhongge Lu have found that germinating seeds in the presence of cytokinins and/or auxins increased in vitro shoot multiplication and seedling quality enhancement in the shrub. The application of certain cytokine Benzyladenine was found to balance seedling development by simultaneously accelerating shoot growth and slowing down root growth, whereas another cytokine Thidiazuron significantly promoted shoot multiplication and proliferation by producing 5-30 shoots per seed. This research and the resulting patent will help ensure a more plentiful and reliable source of Alexandrian laurel in the agricultural marketplace, particularly in the landscape and nursery industries.
