Abstract:

This paper studies the growth of water hyacinth, Eichhornia crassipes, under different environmental conditions, in order to provide information for its control. The results showed strong illumination, high humidity and good ventilation was the suitable condition growth of water hyacinth and could promote the new leaves development and delay plant death. The invariableness condition (in climate chamber) was more helpful for the plant development than natural environment. Cultured in climate chamber, the new leaves and stem of water hyacinth developed fast and stopped growth at 22 days. The leaves gradually died according to the germinating time. The interval between adjacent leaves of the same plant almost had no significant difference as between 3.0-6.0 days, while the average interval between adjacent leaves among different water hyacinth samples also didn't perform significant difference as between 4.1-5.7 days.
