1. Potted plant assaying showed that vetiver could survive for 3 months in summer and 5 months in winter when they were fully flooded, and vetiver could resume to grow gradually after removal of flooding.
2. Flooding inhibits the elongation of vetiver roots, and the younger seedlings were,the severer inhibition was. On the condition of f...
