Research about the Leaf Stomata Changes Influence the NAI Release under High-voltage Pulse Stimulation to the Plants Rhizosphere

摘要

Negative Air Ions (NAI) was regarded as an important indicator of air quality. Some plants can release large amounts of air negative ions under the highvoltage pulse stimulation. A further study on the mechanism has an important value of scientific research and practical. In this paper, it was verified that there is a low positive relationship between the width of the leaf stomata and the NAI content and that there is a significant positive relationship between stoma density and the NAI content, by researching on the changes of leaf stomata and NAI content of plants upon high-voltage pulse stimulation. At last, the causes for the relations-hip has been discussed and studied.
