Proline Enhances Resistance and Recovery of Oilseed Rape after a Simulated Prolonged Drought.

This study was carried out to evaluate the effect of exogenous proline on the growth, biochemical responses, and plant recovery of drought-stressed oilseed rape plants after renewed irrigation. The experiment was conducted under controlled laboratory conditions. After 21 days of cultivation, 3-4 leaf stage seedlings were sprayed with proline (1 mM), then subjected to prolonged drought stress for 8 days to achieve a severe water deficit, next, irrigation was resumed and recovery was assessed after 4 days.

Gibberellic Acid (GA) Applied to Flowering Decreases Seed Viability Even If Seed Development Is Not Inhibited.

Sosnowsky's hogweed ( Manden.), an important invasive species in Eastern Europe, is a monocarpic perennial plant that propagates exclusively by seeds. Hence, interfering with seed viability could help control its spread.

seed development under the effect of exogenous application of GA.

Numerous studies have demonstrated the impact of exogenous gibberellin on fleshy fruit formation, but the effect on dry fruits is not yet well known. To test the role of gibberellin (GA) in dry fruit formation, we analysed the impact of exogenous GA on the invasive plant Sosnowsky's hogweed ( Manden.) seed development and germination.
