Trees normally grow from seeds that naturally fall off from the mother tree and germinate on their own on the ground. In time, the seeds grow to become mother trees themselves, bear flowers and cast off seeds that carry on the time-honored cycle of growth. But it takes ages for trees to produce good seeds, and the imperative of the times is to produce planting materials en masse as quickly as possible to meet the critical demand for reforestation and plantation establishment. Holding a lot of promise is tissue culture, a conventional biotechnology tool.
