Özet
The effect of Storm (fertilizer with 3% growth regulators from Sargassum and A. nodosum algae and 6% organic N) on germinationparameters and seedling vigor in rice was examined in seed from San Andrea cultivar produced in 2017 and 2018, treated withthree concentrations: 0.1%, 0.5% and 2.5% against a control (no fertilizer added). Germination energy, total germination,germination speed, seedling (root, shoot and total) length and dry weight and vigor indexes (I and II) were examined. The resultswere statistically evaluated by two-way ANOVA and LSD test. The total germination (94.38% to 96.75%) was not affected by thetreatments, while the germination energy and the germination speed were significantly negatively affected by the 2.5% treatment83.00% and 21.53 accordingly against 90.63% and 23.94 in the control). All Storm treatments significantly increased the seedlinglength. With the increase in concentration, the root length decreased while the shoot length increased. Even thought all of theStorm treatments significantly increased the Vigor index I (1587.44 to 1644.75) and Vigor index II (35265.38 to 37753.75)compared to the control (1362.07 and 29984.50 respectively), they affected the seedling development differently. The 2.5%treatment negatively affected the development of the seedling, as promoted increased development of the seedling shoot, butinhibited the development of the root. Best results were obtained with 0.1% concentration, as it significantly promoted both theroot and shoot development and resulted in significantly higher index I, index II, shoot, root and total seedling length comparedto the control. With this treatment were obtained the longest root (7.98 cm), the highest root dry weight (3.89 mg) and the highestroot volume (50 ?L) in the trial.
