Abstract: In the present investigation, in the first place, the effects of various inorganic salts on pollen tube growth were observed. Used salts were FeCl3, SnCl2, KCl, MnCl2, MgCl2, CaCl2, NH4Cl, NaCl, ZnCl2, CoCl2, BaCl2, SrCl2, aad AgNO3. Observed flowers were Rhododendron japonicum, Ptsum Sativum. Iris Pseudacorus, Hypercium chinese Impatiens balsamina and Thea Sinensis, Conirary to commonly believed results, on suitable conditions, growth-promoting effects on pollen tube of some salts, such as FeCl3, SnCl2, KCl, CaCl2, NH4Cl etc. were observed. In case of agar media containing 10 percent cane sugar, optimum concentration may be 0.00001-0.0001mol, but in case of water media it should be more dilute.In the second place, observations about function of sugar, about relation between starch grains, osmotic pressure and pollen tube growth, and about daily change of osmotic pressure of pollen grains were done.
