| Outline of Final Research Achievements |
We administered aqueous solution of amino acids containing glutamic acid (Glu), cysteine (Cys) and glycine (Gly), combination of 2 kinds of amino acids, or individual amino acid, to Japanese cedar, Japanese cypress, Eucalyptus, and Arabidopsis. As the results, amino acid aqueous solutions containing Cys stimulated the growth in all plants, particularly 1 to 2mM amino acids of Glu, Cys and Gly was the most effective for the plant growth. The above amino acids solution caused the retardation (delay) of senescence in Arabidopsis, resulting in the lengthening of photosynthetic period.
