Abstract
Pří stimulaci dýchání listů pšenice fluoridem při 100 až 200 p. p. m. fluoru v suché tkáni se zvyšuje poměr radioaktivit14CO2 uvolněného z glukosy-6-14C a z glukosy-l-14C (C6/C1) hlavně zvýšením výdeje 6-14CO2, což svědčí o aktivaci glykolytického systému. Absolutní hodnoty radioaktivity14CO2 jsou působením fluoridu sníženy v důsledku brzdění transportu glukosy do listů.
Summary
During stimulation of wheat leaf respiration by fluoride at 100 to 200 p. p. m. fluorine in dry tissue the ratio of radioactivities of14CO2 released from glucose-6-14C and that released from glucose-l-14C (C6/C1) increases due especially to an increased output of 6-14CO2 which suggests an activation of glycolysis. The absolute values of radioactivity of14CO2, however, are decreased by the action of fluoride due to its inhibition of the transport of glucose into leaves.
Abstract
Нри стимуляции дыхания листьев пнценицы фторидом при 1–2. 10-4 фтора в сухой ткани растет отношение радиоактивностей14CO2 освобожденного из глюкозы-6-14C н из глюкозы-1-14C (C1/C6) нрежде всего из-за новышения выдачи 6-14CO2, что свидетель-с твует о активации гликолитической системы. Абсолютные значения радиоактивности14CO2 действием фторида понижены вследствие торможения транспорта глюкозы в листья.
