“…Use of CCC @ 600 and 800ppm produced the lowest number of suckers, which was much less than control treatment. This is in agreement with the findings of Mzabri et al [28]. The higher number of sucker production by using GA 3 might be due to increase the number and size of leaves as a result of higher translocation of the photosynthates and eventually that would have been used for the production of propagules (suckers).…”

“…The C. indicum flower has a strong aroma and many of the previous studies focused on the essential oil of this plant [13]- [15]. Khan et al [16] observed that the plant height (54.0 to 66.0 cm); number of leaves per plant (208-240); leaf size (4.5 to 8.5 cm); plant spread (19.0 to 32.0 cm); number of branches (4 to 12); number of flowers (25)(26)(27)(28)(29)(30)(31)(32)(33)(34)(35)(36)(37)(38)(39)(40); stalk length (8.8 to 13.3 cm) and days of first flowering (55 to 70 days) varied; respectively in T 7 (100% rice husk) to T 3 (100% cocodust). The different color of leaves and flowers in chrysanthemum flower crop and also the maximum flower period was observed early December-February in germplasms.…”

A field study was conceded to assess the effect of plant growth regulators on growth and quality flower production of chrysanthemum at Horticulture Research Centre (HRC), Gazipur, Bangladesh. The experiment was laid out in Randomized Complete Block Design (RCBD) with ten (10) treatments and three replications. The treatments of plant growth regulators concentration were T1-50 ppm GA3, T2-100 ppm GA3, T3-150 ppm GA3, T4-400 ppm CCC, T5-600 ppm CCC, T6-800 ppm CCC, T7-250 ppm MH, T8-500 ppm MH, T9-750 ppm MH and, T10-Control. The maximum spreading of plant (27.0 cm) was observed when plants were treated with GA3 @ 150 ppm where the minimum plant spread (16.8 cm) was recorded in plants treated with CCC @ 800 ppm. The higher number of suckers (33) per pot was produced when pots were treated with GA3 @ 150 ppm whereas, application of CCC at three different concentrations produced lower number of suckers. The highest number of flower (40) was recorded with 150 ppm GA3, where minimum number of flowers (25) per pot in 800 ppm CCC. The plants sprayed with 50 ppm GA3 took 48 days to flower initiation, whereas, it took 70 days with 750 ppm MH. the highest plants recorded (7.40 cm) with 800 ppm CCC, whereas, lowest size (6.50 cm) was obtained with the application of 500 ppm MH. The maximum vase life of flowers was recorded for the treatment 800 ppm CCC (15 days), which was at par with 13 days vase life obtained by spraying 600 ppm CCC. Therefore, it is concluded that the GA3 acted as growth promoter and the CCC acted as growth retardants on yield and quality of chrysanthemum.

“…The effect of GA on ower characteristics could be because of its effect on photosynthesis activity which led to an increment in metabolic processes in plants(Ghatas 2016). In agreement with our study,Mzabri et al (2021) expressed that saffron corms which were soaked by GA reached ower time sooner. GA regulates the leaves sugar content by stimulating the sucrose phosphate synthase enzyme activity in plants(Kozłowska et al 2007).…”

Saffron is an important plant whether in the food or medical industry. So, improving stigma quality and quantity is of special importance. To evaluate the effects of chemical/hormone treatment on saffron yield and stigma quality, its corms were treated with Gibberellic acid, 6-Benzylaminopurine, Salicylic acid, and Potassium nitrate. Some floral traits such as flower fresh weight, stigma length, stigma weight, and some quality traits (crocin, picrocrocin, and safranal) and corms’ total sugar and starch content were measured. The results showed significant differences between control and treatments, in a way that in all floral traits, picrocrocin, and safranal, an improvement was observed in treated corms. Also, corm total sugar and starch content were affected by treatments. Correlation analysis showed a positive relationship in some studied traits such as stigma dry weight and stigma length, stigma dry weight and flower fresh weight (r = 0.410) as well as in picrocrocin and safranal. While, a negative correlation was detected in day-to-flowering and flower fresh weight, day-to-flowering, and safranal. Almost all floral traits had a positive correlation with corms’ starch content and a negative correlation with corms' total sugar. Generally, it could be pointed out that earlier flowering was in a positive relationship with quality and quantity traits in this plant. Consequently, exogenous chemical/hormone treatments in appropriate dosage would lead to earlier flowering and improve saffron yield and quality.

Agronomic Impact and Phytotoxicity of Olive Mill Wastewater as a Biofertilizer on <i>Vicia faba</i> L.

The Moroccan olive oil industries generate a substantial amount of olive mill wastewater (OMW), causing a significant environmental issue. Consequently, its valorization represents a sustainable agroecological solution to the environmental problems caused by this uncontrolled discharge. In this context, the use of OMW as an organic biofertilizer in agriculture has been suggested as an alternative to restore soil fertility and improve agricultural production. To comprehensively understand its impact, the conducted study focused on the local cultivar Vicia faba L., investigating the consequences of daily applications of OMW at varying doses (5%, 10%, 20%, 30%). In the experimental design, NaCl solutions, mimicking the electrical conductivity of OMW, were used to pinpoint the potential phytotoxic agents within the wastewater. The results revealed that a high dose of OMW had significant effects on morphological, physiological, and biochemical parameters. Additionally, phytotoxicity depended on both OMW concentration and the growth stage of Vicia faba L., causing growth delays, germination inhibition, as well as the accumulation of proline and soluble sugars. These findings underscore the complexity of using OMW in agriculture and highlight the critical importance of precise control over application rates for the success of this approach. While reusing OMW presents a viable and practical solution, a nuanced understanding of its impact on specific crops and a meticulous approach to dosage management are imperative to realize its potential benefits and mitigate any potential risks to crop productivity.
