In this paper, the author has systematically ela brated the turnover of
amino acids in soll and organic manure,the absorption of amino acids by
plants, the interaction between amino acids and inorganic nitrgen the
possible a bsorption mechanisms the inversion of absorbed amino
acids in plants and their effect on the plant physiological process.
it is pointed out thal many kinds of amino acids can easily be absorbed
in molecular forms by plants, and some plants prefer amlno acids such as
Arg to in organic nitrogen. The absorption of amino acids is an active
process,which is inhabitad by respiration inhabitors. The absorbed amino
acids can immediately participate in plant metabolism. Methionine has a
negative effect on plant growth br incresing the synthesis of ethylene
and inhabiting the transform of Asp to other amino acide Many kinds
of amino acids can stimulate plant growth and provent plants from the
toxity of heavy metal ions. The amino acids absorbed directly by planl
roots not only provide plants with nitrogen but also have signifcant
effect on plant metabolism.
