Low temperature requirement deciduous trees of spontaneous dormancy period determination method

摘要

PROBLEM TO BE SOLVED: To provide a method for quickly and securely at units of trees judging the spontaneous dormancy awakening period of a low temperature requiring deciduous tree, without being affected by weather warming and abnormal weather.;SOLUTION: This method for judging the spontaneous dormancy awakening period of a low temperature requiring deciduous tree includes judging whether the spontaneous dormancy awakening period arrives or not, using as an indicator, the content of translocation sugar in vessel liquid. Furthermore, the judging method includes judging whether the spontaneous dormancy awakening period arrives or not by using as an indicator, a Brix indication value or a TOC content of the vessel liquid, and also the judging method includes judging whether the spontaneous dormancy awakening period arrives or not by mixing the vessel liquid with a potassium permanganate solution and using as an indicator, a color tone after color reaction of the mixed liquid.;COPYRIGHT: (C)2013,JPO&INPIT
