Abstract

Abstract: In order to provide theoretical reference for quality improvement of alfalfa, Medicago varia‘Xinmu NO.1’was used as the material, and histochemical staining method was used to study the effect of irrigation amount on distribution rule of lignin monomer in alfalfa stem. The results showed that the height and nodes of alfalfa were larger under higher irrigation amount. Irrigation amount had significant effect on the thickness and proportion of lignin monomer in alfalfa stem. There were more lignin monomers in alfalfa stem under the irrigation amount of 750 m3/hm2. Besides, there were significant differences in the distribution between G lignin monomer and S lignin monomer, and the thickness and proportion of S lignin monomer were higher than that of G lignin monomer.
