“…Limited research was conducted on the relationship between growth-regulating components and the quality of the active ingredients in saffron. In general, the results obtained in this section and the tendency to increase the quality of the active ingredients by applying GA3 are consistent with the results presented by Isfahani et al [34] and Ameri et al [20].…”

“…ese results have been confirmed by those reported by Rudnicki et al [32] on tulips (Tulipa gesneriana L.), Kumar et al [26] on carnations ((Dianthus caryophyllus), and Ameri et al [20] on saffron (Crocus sativus). e same finding was observed in the second year of the experiment.…”

“…A positive correlation was also recorded between leaf area (SF) and percentage of large daughter corms (CWC) (r � 0.92) and coefficient of corm propagation (CPC) and total corm weight (PC) (r � 0.90) and percentage of large daughter corms (CWC) (r � 0.91). ese correlations between flowering parameters such as flowering rate and vegetative growth parameters such as leaf area and underground parameters underline the important role that photosynthetic organs and storage organs play in the precocity and productivity of saffron [20,50,57,61].…”

“…In saffron, corm dormancy is strongly associated with abscisic acid (ABA) [16], and the recovery of apical buds requires gibberellin (GA 3 ) [17]. ere are a few reports on the effect of plant growth regulators on the recovery of saffron corms [1,[18][19][20]. As an extension of previous studies and considering the important properties of gibberellic acid, this experiment was conducted to study the influence of various doses of GA3 applied at different stages on the reproductive and vegetative characteristics of saffron.…”

The present study was conducted to evaluate the influence of gibberellic acid (25, 50, 100, and 200 ppm) applied on saffron corms previously harvested during different periods (March, June, and before planting) on the growth and the quantitative and qualitative yield of saffron (Crocus sativus L.). The study was carried out in the field during the 2016-2017 and 2017-2018 seasons in the experimental station of the Faculty of Sciences of Oujda (Morocco). The measured parameters correspond, on the one hand, to morphometric measurements and to the determination of the saffron stigma yield and, on the other hand, to the evaluation of the quality of the spice. The results showed that almost all the parameters studied were significantly affected by the factors considered. The treatment of corms just before planting with concentrations of 100 and 200 ppm GA3 showed the highest flower and leaf appearance rate and the highest leaf length and surface area. Moreover, the application of GA3 during the month of March gave the best results in terms of stigmata yield, percentage of large-diameter daughter corms, and the ratio of the number of flowers produced to the total weight of corms. The results of the coefficient of corm propagation revealed that the application of gibberellin during any period improved this coefficient compared to the control. The results indicated that the application of GA3 with concentrations above 25 ppm can improve the growth of saffron and increase its yield under the semiarid climatic conditions of eastern Morocco.

“…The same results were found in other studies, on carnation (Kumar et al, 2003), Lilium (Mojtahedi et al, 2014), and gladioli (Padmalathaet al,2013). These correlations among flowering parameters include the number of flowers and diameter of flowers and morphological parameters such as total leaf area, plant height underline the chlorophyll content play in the productivity and precocity of chrysanthemum (Mollafilabi, 2004;Douglas et al, 2014 andAmeri et al, 2019).…”

Ornamental plants are grown all over the world. In most countries, Chrysanthemum is considered one of the most popular cuts and potted flowers. Plants were sprayed with gibberellic acid (GA3) at concentrations (100, 200, and 300 ppm) and methionine (ME) at levels (200, 400, and 600 ppm), as bio-growth stimulants in the pre-blooming stage. The morphological and flowering parameters significantly increased by increasing the concentration of GA3. The highest values of K%, P%, total carbohydrates content, total phenols, total chlorophylls, and carotenoids in the leaf were obtained from gibberellic acid treatment at the rate of 300 ppm, while methionine at 600 ppm gave the highest value of protein in flowers. Also, various levels of gibberellic acid application significantly showed variation for days to initiation of Chrysanthemum flowers. The results of leaf anatomy showed an increase in most characteristics such as (thickness of the main vein, lamina, and spongy tissue) under study when spraying with gibberellic acid, especially at the concentration of 300 and methionine 600 ppm; respectively compared with control. Furthermore, inter-simple sequence repeat (ISSR) analysis has provided a powerful molecular marker for identifying variation with control and the best treatments. Therefore, the utilization of 300 ppm GA3 a plant growth regulator and 600 ppm ME an amino acid, these treatments are recommended to enhance Chrysanthemum parameters which lead to increasing its economic value as cut flowers and flowering potted plants as well as pharmaceuticals industries and multi-chemical uses. Keywords: Cut flowers; bio-growth stimulants; ISSR; leaf anatomy, growth regulators.
