Inhibition of the growth of apple pollen tubes by EDTA, surfactants and fungicides

摘要

The effects of EDTA (ethylene diamine tetraacetic acid), Kresoxim-methyl, Wettable Sulphur 80 WP and the surfactants Triton X-100, Triton X-114, Dehydol TA 5 and Dehydol TA 29 on pollen tube growth of Malus domestica Borkh. cvs 'Golden Delicious' and 'Mondial Gala' were determined by image analysis. The ED50- and ED90-values (effective doses giving 50% and 90% reduction of growth) of the chemicals, except for the surfactants, were determined.
