Abstract

The effect of several nitrogen compounds on the germination of the first seed of each spikelet ofAvena sterilis spp.macrocarpa Mo. was studied on Petri dishes placed in germination chamber. The compounds assayed were ammonium sulphate, ammonium nitrate, urea and calcium nitrate, generally used as fertilizer for cereal crops, as well as a control supplied with water only

The concentration of the assayed compounds were 100, 1000, 2500 and 5000 ppm either at a constant temperature of 15 ° C or at alternated temperatures 5°C and 15 °C, for 16 and 8 h, respectively

Significant increase in the germination percentages occurred when nitrate compounds were used in relation to other compounds and no significant differences were found between the urea, and ammonium sulphate. This increase became significant at 1000 ppm, and therefrom until 5000 ppm germination stabilized. In the case of urea, very high abnormal germination percentages were obtained at 2500 ppm, while the effect turned noxious from 5000 ppm

The use of alternating temperatures significantly increased the germination capacity of the wild oat seeds in the case of urea, ammonium sulphate and ammonium nitrate.

It is found that nitrates are capable of breaking the dormancy ofAvena sterilis spp.macrocarpa Mo. seeds, which according to various authors, is due to an increase of the respiratory activity of the seeds
