Efectul șocului termic a temperaturilor suboptimale pozitive și a preparatului Reglalg asupra indicilor germinativi ai semințelor de castravete Cucumis Sativus L

Cucumber (Cucumis sativus L.), cv Concurent and forms as Plai, F1; ELITA, F1; ASSIA, F1; Viorel, F1 și Cernomor, F1 seeds treated with distillate water (control) or water solutions of Reglalg preparation (1/100 and 1/1000 dilutions) were germinated at 27°C (control) or at different sub optimal positive low temperature (15°C, 13°C, 10°C, 8°C, 6°C and 4°C) to study germination characteristics. Final germination percent of cv Concurent seeds and germination energy decreased, while the conditional number of days, required for germination of one seed, increased with the decrease of temperature. The temperature of 13°C is the minimum below which all cucumber seeds do not germinate. Application of Reglalg preparation (dilution 1/1000) had a beneficial effect on the germination parameters under suboptimal temperature of 15⁰C.
