“…However, our experiment showed that low temperature could reduce the length of dormancy period and stimulates flowering. Hajyzadeh et al [28] reached the same result as ours and indicated that cold-stored corms had earlier flower induction in saffron. However, other data, which were not listed here, showed no preference to use precold treatment.…”

Saffron is an important flowering plant, generally known as a golden condiment. The present study was performed to find the influence of different levels of SA and pre-cold treatment in the dormancy period of saffron and their effects on content enzyme activity. The results indicated that the SA2%, SA1%, and, pre-cold treatments took the shortest day to flowering. PAL enzyme activity was highest in pre-cold treatment. The higher total amount of protein was measured in the control, SA1% and SA2%. The highest amount of starch content and total soluble sugar was detected in pre-cold, SA2%, and control, respectively. No significant differences between treatments were present for CAT, PPO, GPX, and APX enzymes activity. There was a negative significant correlation between flowering time and some studied traits, i.e., starch and PAL activity. Applying SA and pre-cold treatment can induce saffron flowering and effect on pal enzyme activity and corm total protein, sugar, and starch content accordingly.

“…In the study an increase was observed in iron chelate applications on corm weight, the number of corms, daughter corm ratio and unit corm weights compared with the control application as in the literature study. The values obtained regarding the corm weights of saffron in different studies, the present researchers have done in Hatay conditions are as follows; the plot corm weight was between 87.33 and 219.00 g (Yıldırım et al 2017a), the corm weight was between 19 and 219 g 150 m-2 (Yıldırım et al 2017b) and in another study, the corm yield per plot was 84-527 g/plot (Hajyzadeh et al 2017) and, this study, corm weights ranged from 277.77 to366.57 g. According to the studies conducted under Hatay conditions and the literature values, these study results were obtained above the average. Thus it may be said that iron chelate treatments have a positive effect on corm weight.…”

Effects of different doses of chelated iron (EDDHA-Fe) on the yield and quality of saffron leaf, corm and stigma were investivated. The highest weight of harvested corms was obtained when treated with 2 g of iron chelate per corm, 366.57 g, and the highest number of corm was obtained when treated with 4 g of iron chelate per corm, 73.00 g. When the effects of the iron chelate treatments on the quality of the stigma studied, it was found that the treatment with 2 g of iron chelate per corm gave a yield of dry stigma 754.00 mg and the highest average amount of safranal of 1386.50 mg/kg. The treatment with iron chelate had a positive effect in increasing the yield of the corm, the yield of dry stigma, and the quality of stigma saffron. Bangladesh J. Bot. 52(1): 97-103, 2023 (March)

“…C. sativus flowers best in a warmintermediate temperature sequence (Molina et al, 2004). Indeed, the direct storage at a low temperature of the corms acts on the precocity and extension of the saffron flowering season (Molina et al, 2005;Cavusoglu 2010;Mzabri et al, 2017;Hajyzadeh et al, 2017) which invalidates the results found in this trial. In addition, the results showed that flower number and stigma yield were negatively affected by the thermal forcing of the corms.…”

“…Similarly, (Molina et al, 2004) found that the transfer of bulbs after floral initiation at a temperature below 15 °C, caused a drastic reduction in the number of flowers formed. While (Hajyzadeh et al, 2017) proved that corms stored in cold storage showed a better yield of saffron and had positive effects on all components of the plant. The reduction of yield parameters (number and size of flowers) due to low-temperature storage was closely dependent on the stage of development of the mother corms, storage conditions, and duration (Molina et al, 2005).…”

Among all environmental factors, the temperature is considered one of the key elements that control the growth and development of saffron. This study was undertaken to investigate the effect of thermal forcing of corms on saffron growth and development. To this end, mother corms were collected at four different periods: late March (T2) , mid-April (T3) , late April (T4), and after leaf senescence (Control, T1) . The corms of each period were then pretreated at three successive temperature levels: at 25 °C for 2 weeks, at 15 °C for 2 weeks and finally at 4 °C for 12 weeks. The results showed that the thermal pretreatment of corms had a significant effect on some saffron parameters. The flowers of the corms that underwent thermal treatment were later than those of the control. Similarly, the flower numbers and stigma yield were negatively affected by thermal forcing of corms. Overall, the thermal forcing of corms under the proposed regime was unfavorable for the growth and development of saffron.
