  • Tolerance improving agent for plants
    Patent number: 10874101
    Abstract: Provided is a tolerance improving agent that can increase or improve environmental stress tolerances (high-temperature tolerance, drought tolerance and the like) of plants. The tolerance improving agent is constituted of at least one kind of unsaturated carbonyl compound selected from unsaturated aldehyde and unsaturated ketone. Such unsaturated carbonyl compound is, for example, a compound having 4-9 carbon atoms, which does not have an unsaturated bond at the terminal, and may be at least one kind selected from ?,?-alkenal, ?,?-alkanone, ?,?-alkenal, ?,?-alkanone, ?,?-alkenal, ?,?-alkanone, ?,?-alkenal, and ?,?-alkanone.
    Type: Grant

  • Method for simply quantitatively determining hexavalent chromium technical field
    Patent number: 8093059
    Abstract: Provided is a method for simply quantitatively determining hexavalent chromium, including: separately bringing a plurality of test solutions into contact with a sample, the plurality of test solutions each containing a color change agent which changes in color upon reaction with hexavalent chromium, and an acid which dissolves the sample, the plurality of test solutions having different contents of the acid from each other; detecting color change in each of the test solutions; and when the color change is detected, specifying a range of content of hexavalent chromium in the sample on the basis of the content of the acid in a test solution with the color changed among the plurality of test solutions.
