Two pots experiments were conducted at the Experimental Farm of El-Qassasin Horticultural Research Station, Agricultural Research Center, Ismailia Governorate, Egypt, during two successive seasons of 2016/2017 – 2017/2018, to investigate the effect of potassium silicate at (0, 4, 6, and 8 cm3/l) as a foliar spray under different levels of water salinity (tap water, 1000, 2000 and 3000 ppm) on Calendula officinalis L. plant. The experiment was performed in complete randomized block design as factorial experiment with 3 replicates. The obtained results cleared that using salinity levels decreased growth parameters (plant height, number of branches/plant, fresh and dry weights of herb/plant), flowering parameters (flower diameter, number of flowers/plant, fresh and dry weight of flowers (g/plant) during eight cuts and fresh and dry weight of flowers (g/plant/season)) and chemical constituents (chlorophyll a, chlorophyll b, carbohydrate and carotenoid contents) compared to control. Moreover, the highest values in these parameters were registered by potassium silicate at 8 cm3/l concentration. Proline content increased in leaves with using saline water at 3000 ppm + potassium silicate at 8 cm3/l. Generally, it could be concluded that potassium silicate at 8 cm3/l, showed a uniform impact in alleviating inhibition of Calendula officinallis L. plant growth and productivity under moderate salinity stress condition.

RCBD design with three Replications was used. Results showed that highest average of leaf length, dry percentage of Vegtative growth, Chlorophyll percentage, roots length, root diameter, dry weight of roots for Both cultivars due to the irrigation with the magenetized water with 1000 Gausses reached up to (14.95cm, % 28.90, % 42.98, % 2.98). However there was a signification increase in treatment on mucilage percentage in leaves and roots reached up to (2.85, 1.02)% compare with control treatment. The highest percentage of dry weight leaf and root, Chlorophyll percentage and mucilage percentage of leaf and root at Yellow queen reached up to (28.24%, 42.40%, 2.72%, 5.70mm, 2.91gm 0.94%).

In this research, the effects of different concentrations of jasmonic acid ( JA) on growth parameters of flower diameter, number of flowers, dry flower weight, plant height, 1000-seed weight and also, photosynthetic pigments in marigold (Calendula officinalis L.) were investigated. To achieve this aim, marigold planted in pots and jasmonic acid were sprayed on the shoots at concentrations of 0.75, 150 and 225 μM. Data were compared by Duncan test. The results showed that different concentrations of jasmonic acid significantly affected the dry flower weight, plant height and 1000-seed weight. The maximum plant height and 1000-seed weight were reached by 150 μM jasmonic acid, while 225 μM was recorded the dry flower weight.

The studies was defined qualitative and quantitative composition of flavonoids in lichen species Physcia stellaris (L.) Nyl., Collected in habitats with different levels of anthropogenic load. Changes in the composition of flavonoids is considered in the literature as an indicator of the direction of the synthesis of secondary metabolites by plants to protect against adverse environmental influences. It was found that the most diverse number of members (128 compounds), phenolic substances found in the least contaminated RB Ishimbai area and the fewest (58 compounds) was detected in Sterlitamak. Analysis of qualitative and quantitative composition of flavonoids showed that in the area of Ishimbaisky samples were found to accumulate naringin, dihydroquercetin, quercetin. The samples obtained in Alsheyevsky District noted in content highs routine, but samples Sterlitamak – fizetina and naringenin. The calculation of the potential antioxidant status showed that the samples of Ishimbaisky district formed the highest level of protection phenolic substances. It showed no direct correlation between the growth response to environmental pollution and the level of flavonoid content in the thallus of lichens.

Calendula officinalis L. plants were fertilized with urea (46% N), ammonium nitrate (31% N), and ammonium sulfate (20% N) at 0, 25, 50, or 100 kg N/Feddan (4200 m2). The plants also received calcium superphosphate (15.5% P2O5) and potassium sulfate (48% K2O) at 100 and 50 kg/Feddan, respectively. The results showed that fertilizers enhanced vegetative growth and improved flowering aspects compared to control plants. Application of urea at 50 kg N/Feddan gave the highest flower number (119) and flower dry weight (183 g). Moreover, the applied fertilizers increased the content of photosynthetic pigments (chlorophyll a, chlorophyll b, and carotenoids) in leaves and flowers and the N percentage in shoots. Nevertheless, P and K percentages were decreased.

In order to initiate hairy root culture initiation cotyledons and hypocotyls of Calendula officinalis L. were infected with Agrobacterium rhizogenes strain ATCC 15834 or the same strain containing pCAMBIA 1381Z vector with β-glucuronidase reporter gene under control of promoter of NIK (Nematode Induced Kinase) gene. The efficiency of induction of hairy roots reached 33.8% for cotyledons and 66.6% for hypocotyls together for both transformation experiments. Finally, eight control and nine modified lines were established as a long-term culture. The hairy root cultures showed the ability to synthesize oleanolic acid mainly (97%) as glycosides; control lines contained it at the average 8.42 mg · g(-1) dry weight in tissue and 0.23 mg · dm(-3) in medium; modified lines: 4.59 mg · g(-1) for the tissue, and 0.48 mg · dm(-3) for the medium. Additionally lines showed high positive correlation between dry/fresh weight and oleanolic acid concentration in tissue. Using the Killiani mixture in acidic hydrolysis of oleanolic acid glycosides released free aglycones that were partially acetylated in such conditions.
