    摘要: A method for treating plants with a plant growth promoter comprising 5-aminolevulinic acid or a salt thereof as an active ingredient. This treatment method is effective in enhancing the photosynthetic activity of a plant, enhancing its ability to absorb CO.sub.2, suppressing its respiration, increasing its chlorophyll content and promoting its growth. As a result, the treatment greatly contributes to the promotion of rooting, the reduction of lodging, an increase in yield, an improvement in cold resistance, maintenance of freshness, an improvement and maintenance of green color, the growth of good seedlings, the promotion of organs, an increase in tillers, a shortening of the time required for growth, a relief of chemical damage and an increase in the rooting ratio in, for example, cutting.
