Studies on the Effects of Clipping Tobacco Seedling and Deep Transplanting on Plant Growth and Development

It was determined that length of the longest root produced from stem buried in soil was about 10cm at the seventh day after transplanting. Complementation of seedling with 10~15cm stem-length and deep transplanting stimulated significantly tobacco roots and leaves grow th and development, which increased fertilizer efficiency and drought tolerance, and reduced the possibility of plants blowing over in a windstorm.
