Effects of Kinetin and Salinity on Germination of Tomato, Barley and Cotton Seeds

The role of hormones in regulating the germination of polymorphic seeds and early seedling growth of Atriplex triangularis under saline conditions

“…Dormancy induced by high salt concentrations in halophytes could be alleviated by the application of GA, (Ungar and Binet 1975, Boucaud and Ungar 1976a, Ungar 1977, 1984a, but no such stimulation of germination was reported for kinetin treatments alone. However,, in glycophytes, dormancies induced by salt, mechanical or osmotic stress were partially alleviated by exogenous application of kinetin (Boothby and Wright 1962, Odegbaro and Smith 1969, Kaufmann and Ross 1970, Hegarly and Ross 1979, Ross and Hegarty 1980, Bozcuk 1981. Small seeds of A. triangularis have larger diameter epidermal cells than do the medium and large seed sizes.…”

The Tomato Crop

“…As a whole, the tomato is considered moderately salt-tolerant (Nieman, 1962), and it has been observed that exposure of seeds to sodium chloride levels of 75 mM decreased the germination of tomato seed by only 13 % as compared to controls (Boscuk. As a whole, the tomato is considered moderately salt-tolerant (Nieman, 1962), and it has been observed that exposure of seeds to sodium chloride levels of 75 mM decreased the germination of tomato seed by only 13 % as compared to controls (Boscuk.…”

Effect of Salinity and Plant Growth Regulators on Seed Germination of Medicago sativa L.

“…In Medicago sativa, Trifolium brachycalycium, lettuce and others, seed germination was reduced with increase in NaCI concentration (Aparacio et al, 1981;Scorer, et al, 1985;Khan and Rizvi, 1994). Plant growth regulators are effective in preventing or reducing the adverse effects of salinity on germination (Braun and Khan, 1976;Bozcuk, 1981;Khan arid Rizvi, 1994;Khan and Ungar, 1997). The present study was under taken to see the effect of some growth regulators and salt stress on seed germination of Medicago sativa, an important fodder crop.…”
