SIMPLIFIED EVALUATION METHOD AND DEVICE FOR FREEZING AND LOW-TEMPERATURE STRESS RESISTANT LEVELS OF PLANT

摘要

PROBLEM TO BE SOLVED: To provide a method for evaluating easily freezing and low-temperature stress resistant levels of a plant in a short time, without killing the plant.;SOLUTION: One part of a tissue of an individual grown under a cultivation condition suitable for a plant species from seeding up to an imago plant, for example, a leaf (using one sheet of leaf in the case of a small leaf and having a large number of leaves, one cut part of a leaf in the case having a large leaf), is cut out in the evaluated plant body, to be frozen in water, followed to be returned thereafter to an ambient temperature, an amino acid eluted from the leaf is brought into reaction with ninhydrin, an absorbance in 570 nm is measured by a spectrometer to measure a content thereof.;COPYRIGHT: (C)2006,JPO&NCIPI
