已经开发了一种程序，用于制备植物提取物，用高效液相色谱法或酶分析法定量测定其甘油含量。在田间条件下种植的15种作物叶片甘油浓度在10 - 30亩之间。G / wt组织重量。在相对较强的降雨后大约12小时，玉米、甜菜、大豆、大豆、南瓜和苜蓿叶片的甘油浓度增加了几倍。当大麦植株厌氧24小时时，观察到叶片甘油浓度大幅增加。在厌氧植物中观察到的甘油部分来自根部的甘油合成并转运到叶片，部分在叶片中产生。
A procedure has been developed for preparation of plant extracts for quantitation of their glycerol content using high performance liquid chromatography or enzymatic analysis. Fifteen crop plants grown under field conditions had leaf concentrations of glycerol between 10 and 30 .mu.g/ wt weight of tissue. Approximately 12 h after relatively heavy rains leaves of maize, sugar beet, soybean, bean, pumpkin and alfalfa had several fold increases in concentrations of leaf glycerol. When barley plants were made anaerobic for 24 h, large increases in leaf glycerol concentrations were observed. It is proposed that part of the glycerol observed in anaerobic plants comes from glycerol synthesis in the root and transport to the leaves andpart is produced in the leaves.
