G. Murin et al., THE CONTENT OF FREE ENDOGENOUS CYTOKININS IN DIFFERENTLY AGED SEEDS OF VICIA-FABA, Acta Physiologiae Plantarum, 16(1), 1994, pp. 11-18
We tested the hypothesis that the strong reduction in germination in o
ld seeds is caused by changes in the content of free endogenous cytoki
nins. This hypothesis was not confirmed as extracts of 1, 2, 4, 5, 7 a
nd 8-years old seeds studied by thin-layer chromatography (TLC) and ga
s-liquid chromatography (GLC) did not differ in their cytokinin concen
trations.
