title: Effects of acetylsalicylic acid on germination, growth and chlorophyll amounts of cucumber (Cucumis sativus L.) seeds.
abstract: Germination activities, various growth parameters (primary root length, hypocotyl length, primary leaf length, plant length and increase in fresh weight) and chlorophyll (a+b) amounts of cucumber seeds exposed to 0, 10(-5), 10(-4), 10(-3) and 0.5x 10(-2) M aqueous solutions of acetylsalicylic acid (ASA) for 48 h were established. While 0.5x 10(-2) M ASA significantly prevented germination activity of the seeds, other concentrations did not produce any effect, either positive or negative. Meanwhile, 0.5x 10(-2) M ASA inhibited radicle growth of the germinated seeds, while 10(-5) M ASA increased radicle growth. Other concentrations of ASA did not affect radicle growth. The following findings were obtained from the one-week seedlings exposed to ASA for 48 h: 0.5x10(-2) M ASA prevented growth (lengthening) of root, hypocotyl, leaf and plant and increased chlorophyll (a+b) amount with an increase in fresh weight. Contrary to 0.5x 10(-2) M ASA application, these features of the seedlings (except for the leaf length) were encouraged by 10(-5) M ASA. 10(-3)) M ASA only prevented root growth and reduced chlorophyll (a+b) amount. Other concentrations of ASA did not bring about any positive or negative effect on the features studied.
