METHOD FOR DIAGNOSIS OF CROPS PHYSIOLOGICAL STATE Russian patent published in 1997 - IPC

FIELD: agriculture, in particular, plant selection. SUBSTANCE: method involves exposing test and control variants of seedlings to the action of stresses, light and phytohormones; separating preparation of total ribonucleic acid (RNA) with following separation, in two cycles of affinity chromatography, of preparation of poly-A A⁺⁺- matrix RNA; calculating percentage of output of poly-A A⁺⁺ of matrix RNA of second cycle from poly-A A⁺ of matrix RNA of first cycle; determining physiological state of plants by difference between values of test and control variants. EFFECT: increased efficiency and provision for reliable and precise test results. 4 tbl
