Sunflower, as an oil seed, shows fast deterioration, requiring specific storage conditions. In addition, sunflower crop usually produces dormant "seeds", therefore requiring special conditions for germination. This paper reports a study on dormant sunflower "seeds" with respect to some germination and storage conditions. Various treatments were applied on a stock of sunflower "seeds": a) germination under different temperatures and light regimes; b) intermittent rinsing during different periods of time; c) scarification with concentrated sulfurie acid during different periods of time: d) "seed" storage and conservation. The best results were obtained with the germination at 35oC and with "seed" rinsing in running water for at least 15h; the "seed" conservationat 10oC induced a dormancy release of about 50% after 20 days. At 15oC or 20oC, that value was reached only after more than 2 mounths of storage. |
