Abstract

Germination responses of 14 Hesperis species Hesperis aspera, H. bicuspidata, H. campicarpa, H. cappadocica, H. hedgei, H. laciniata, H. matronalis, H. pendula, H. persica, H. podocarpa, H. schischkinii, H. stellata, H. theophrasti subsp. sintensii, H. transcaucasica distributing naturally in Turkey were tested in this study at different salt NaCl , nitrate KNO3 and acid HCl, HSO4 concentrations Control, 0.5, 1, 2, 3% . Low salt concentration blocked seed germination of eight taxa Hesperis aspera, H. campicarpa, H. cappadocica, H. laciniata, H. pendula, H. persica, H. stellata, H. transcaucasica and also declined seed germination ratio and speed of the others. Although low potassium nitrate concentrations increased germination of all species except H. hedgei, its increasing concentrations decreased it. Hydrochloric acid HCl blocked germination percentage and speed completely of eight taxa Hesperis aspera, H. bicuspidata, H. campicarpa, H. cappadocica, H. hedgei, H. pendula, H. persica, H. theophrastii subsp. sintenisii , while the other six species germinated in its low concentrations. Similarly, sulphuric acid H2SO4 obstructed germination of all except two species, H. podocarpa and H. transcaucasica germinated in low H2SO4 concentration. Significant differences in sensitivity to salt, nitrate and acid were determined among the 14 Hesperis species p
