“…Increased hydrolysis and biosynthesis under the influence of 3C and 4.5C potencies (Figure 1) could be connected to a better substance conversion from the seed rest to the root and shoot. All genotypes showed higher biosynthesis with the highest values achieved for L3, with an increase in hydrolysis to 27% and in biosynthesis to 40% when treated by 4.5C, similarly to Subedi and Bhattarai 30 (when seed was treated with different growth regulators). The 4.5C affected biosynthesis (which is susceptible to injuries) and has a positive impact on the germination of susceptible genotypes, such as L3.…”

“…The sugary lines had lower hydrolysis and biosynthesis in the controls, indicating their poorer ability to germinate and produce strong plants with a high FS (Tables 1 and 2). Subedi and Bhattarai 30 observed that maize germination correlates directly with the mobilization of the endosperm reserve.…”

“…is last observation is in perfect agreement with the work of [51] on saffron. us, the results of previous research have shown that exogenous spraying of GA 3 in some bulbous plants inhibited the growth of lateral buds of mother bulbs, which gave rise to large replacement corms and, therefore, a better flowering yield [52,53]. However, [54,55] found that gibberellic acid had no effect on the number and weight of ).…”

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.

“…Presence of high concentrations of various metals in soil either essential or non-essential causes a significant perturbation in carbohydrates (Jha and Dubey, 2005). As a result of this direct influence on activity of metabolic enzymes of germinating seeds, the level of vital biomolecules including sugars, proteins, amino acids and nucleotides is altered (Subedi and Bhattarai, 2003). Another enzyme, protease is thought to participate in various physiological as well as metabolic process of plants related to protein turnover.…”

To cite this paper: Sadiq, R., M. Hussain, M. Ashraf and K.U. Rehman, 2015. Exogenous application of ethylenediaminetetraacetic acid and oxalic acid improve the seed germination and enzymes activities of sunflower (Helianthus annuus) under cadmium stress. AbstractThe study was conducted to examine the deleterious effects of cadmium (Cd) on metabolic enzymes and their end products during seed germination and the effect of ethylenediaminetetraacetic acid (EDTA) and oxalic acid (OA) in easing the Cd toxicity in two sunflower hybrids (Hysun-33 and FH-533). To accomplish this, a pot experiment was carried out in small sandfilled plastic pots under normal environment temperature (28±2ºC). Seeds of both sunflower hybrids were exposed to Cd levels (250 and 450 mg/kg) alone and in combination of optimized level of chelating agents EDTA and OA (each at the rate of 1g/kg) at the time of sowing. The enzymes activities of two germinating hybrids were recorded over time from 24 to 120 h after sowing. When Cd was applied alone it reduced the germination rate, enzymes activities and total soluble sugars contents. Mobilization of stored proteins and amino acids were also suppressed in germinating seeds of both hybrids. However, application of EDTA and OA in combination with Cd improved the germination rate of seeds by surpassing the biochemical metabolism and enhanced the activities of α-amylase and protease revealing the ameliorating effect to Cd toxicity. Results revealed that minimum values of all the attributes are obtained at 450 mg/kg of Cd level, while chelators treatments proved effective in relieving Cd stress of which OA had 10% more pronounced germination percentage than EDTA and 30% more as compared to control. Interactive studies showed that both the chelators detoxify the 250 mg/kg of Cd more as compared to 450 mg/kg of Cd. Results clearly indicated that sunflower hybrid Hysun-33 showed greater activities of two hydrolyzing enzymes and efficient mobilization of reserved sugars and proteins than hybrid FH-533 under Cd stress, so it can be grown on Cd contaminated soils for higher plant productivity. Thereafter EDTA and OA could be supportive to improve the seed germination security in Cd polluted soil.
