The Effect of Drought Stress on Germination Indices of Rudbeckia hirta L. at Different Temperatures
Subject Areas :

Keywords: Bedding Flower, Propagation, Stress, Growth Rate, Tolerance,
Abstract :
This study investigates the germination response of Rudbeckia hirta to drought stress. Various levels of water potential were applied using polyethylene glycol-6000 at four germination temperatures (15, 20, 25, and 30 °C). The evaluation metrics included final germination percentage, average germination day, germination index, germination rate index, and germination stress tolerance index. Additionally, stem and root length, as well as fresh and dry weight, were measured at 20 °C under different water potential levels. The results indicated that Rudbeckia hirta exhibited greater sensitivity to suboptimal temperatures compared to above-optimal temperatures. A gradual decrease in water potential inhibited and delayed seed germination. Furthermore, the cultivars demonstrated better performance at temperatures below 30 °C. Water stress during seed germination adversely affected the subsequent growth of seedlings under favorable conditions, significantly reducing shoot and root length, as well as fresh and dry weights, in seedlings derived from seeds germinated at water potentials below -0.45 MPa.
