摘要: Es wurde eine Methode beschrieben, die eindeutige quantitative Bestimmung der Endospermzellen in Weizenkornern auch spaten Stadien Kornfullung gestattet. Nach Behandlung mit Pektinase zerfallt das Endospermgewebe Einzelzellen, Starke den wird dabei aufgelost. Die Zellkerne werden Hamatoxylin angefarbt. Ihre Zahlung erfolgt noch erkennbaren Zellstrukturen auf einem Membranfilter Mikroskop, was fur genaue Erfassung aller von Vorteil ist. An improved method for the determination of number endosperm cells wheat grains A is described, which allows a clear and grains even during late stages grain filling. After treatment with pectinase tissue disintegrates single cells, same step starch dissolved. The nuclei are stained hematoxylin, drawn by vacuum on to millipore filter, counted still recognizable cell structures under microscope. This advantageous exact counting all cells.
