Abstract

Background and Objectives: Crocus sativus L. is one of the most important medicinal plants and expensive spice in the world. The export of saffron has made plans for increasing the quantity and quality to compete in the global market is inevitable and will require extensive research anywhere. Therefore, the present study is to investigate the synergistic effects of gibberellic acid and corm weights on vegetative traits and yield of saffron. Materials and Methods: In order to investigate the effect of gibberellic acid and mother corm weights on flower yield and growth characteristics of saffron, a factorial experiment was conducted in a randomized complete blocks design with two levels of gibberellic acid (0 and 20 ppm) and 3 levels of mother corm weights (including groups weighing 0. 1-4, 4. 1-8 and 8. 1-12 gr) in 3 replications at the research farm of Birjand University in 2016. Results: The results showed that mother corm weight was effective on all flowering traits, so that the highest Number of flowers, average fresh weight of flowers, average fresh weight cream and average fresh and dry weight of stigma (0. 381 g per plant, 37. 72% in square meter, 0115 g/plant, 0. 025 and 0. 0046 g/plant) from the treatment of corm weigh 8. 1-12 g and the least of them from corm weighing 0. 1-4 grams were observed. Also, the increase in corm weight increased the leaf traits (leaf length, fresh and dry weight of leaves, chlorophyll a, b and total leaf), so that the highest and lowest of these traits were treated with weight 8. 1-12 g/g and 0. 1-4 g. According to the results of this experiment, it was found that gibberellic acid also had significant effect on most vegetative traits of leaves. For example that the maximum leaf length (32. 02 cm), leaf number (6. 28), average fresh weight Leaf (0. 388 g/plant), chlorophyll a (0. 203 mg/mg/ fresh weight) were obtained from gibberellic acid treatment. But, gibberellic acid only significantly affected the flowering traits, which reduced the Number of flowers. The results of the interaction of treatments showed that the highest amount of chlorophyll b was obtained in corm weigh 8. 1-12 g and consumption of gibberellic acid treatment. Also, the highest mean length of the stigma was obtained from seedlings of weigh 4. 1-8 g and no use of gibberellic acid was obtained. Conclusion: According to the results of this study, coarse mother corm weights (8. 1-12 g) had positive effects on growth characteristics and yield of saffron, while the use of gibberellic acid only improved the vegetative traits of saffron and influenced the flowering traits of saffron did not have.
