Abstract:
Ficus microcarpa (L.) has many aerial roots, which grow from the stem and live in the air causing them to absorb moisture from the air. A lot of literature has reported that aerial roots have the function of moisture absorption, and also can prevent water loss. But very little is known about the characteristic of H2O exchange between aerial roots and the surrounding air. This papermainlyaims to explore the transpiration or moisture absorption of Ficus microcarpa (L.) aerial roots. Two experiments were designed and carried out in China viz., H2O exchange characteristic and vapor absorption experiments. Aerial roots of Ficus microcarpa (L.) was used as experimental material. Results showed that the young aerial roots had the function of transpiration when air relative humidity was less than 90%. The rate of transpiration had a negative relationship with the air relative humidity. The aerial roots expressed the function of moisture absorption when air relative humidity reached 100%. The aged aerial roots had weak and transient moisture absorption and transpiration because of the suberification of root epidermal. The research verified that the aerial roots Ficus microcarpa (L.) function of moisture absorption or transpiration, but the moisture absorption or transpiration mechanism may need further research.
