Calendula officinalis (pot marigold), a medicinal ornamental plant belonging to the Asteraceae family, has various medicinal activities such as anticancer, antimicrobial, antioxidant and antitumor. The retention time of quercetin (6.445 min), kaempferol (11.246 min), caffeic acid (2.333 min), beta carotene (9.614 min) standards, which were planned to be analyzed by HPLC, was determined. The HPLC conditions that are most suitable for these metabolites have been determined. The amounts of quercetin, kaempferol, caffeic acid and beta carotene in the seedling leaves of these two Calendula species on the 0., 15., 30., 45., 60. days were compared. Caffeic acid and beta carotene have been detected in the leaves. However, quercetin and kaempferol compounds were not detected. It was determined that the caffeic acid and beta carotene amounts of C. officinalis species were higher than that of C. arvensis. The highest caffeic acid in both C. officinalis and C. arvensis seedlings (0.4042±0.0123 µg/g dry weight for C. officinalis, 0.1918±0.0437 µg / g dry weight for C. arvensis) and beta carotene amounts (0.8520±0.0692 µg/g dry weight for C. officinalis, 0.6389±0.0189 µg/g dry weight for C. arvensis) were determined on 60. day. In addition, it was determined that the amount of these metabolites differed according to the seedling development period.

Pot Marigold (Calendula officinalis L.) is an annual ornamental plant with yellow to orange flowers which belongs the the Asteraceae family, its flowers are used in the pharmaceutical, cosmetic and food industries. The commercial samples of seeds (n=24) of C officinalis were cultivated in home gardens in Estonia. Total carotenoid contents, determined spectrophotometrically (λ=455 nm) in the inflorescences, varied from 0.7 to 2.7%, the cultivar with the highest carotenoid content was ‘Dracon’. The total content of flavonoids, determined spectrophotometrically (λ=370 nm), varied from 0.8% to 1.7%. The best cultivar contained almost maximum amount of total carotenoids (2.5%) and flavonoids (1.7%) was ‘Radio”. The oil yields of eight cultivars of C officinalis obtained were from 0.10 to 0.43%, the highest yield (0.43%) of the oil was obtained from the cultivar ‘Double Ball’. A total 70 compounds were identified and analysed by GC-MS in the essential oil of C officinalis, representing over 95% from total oil. The major components of the oils (>5%) of C. officinalis cultivars were α-cadinole (18.4-32.0%), γ-cadinene (9.7-18.9%), viridiflorol (2.0-10.0%), τ-cadinole (4.7-7.9%), δ-cadinole (3.3-5.6%), and γ-muurolene (0.8-5.1%). There is no clear relation between the colour of the inflorescences of C. officinalis and the total content of flavonoids and carotenoids. The chemotypes of essential oils of C. officinalis were not found among the cultivars studied.

Agriculture in Mali, a country in Sahelian West Africa, strongly depends on rainfall and concurrently has a low adaptive capacity, making it consequently one of the most vulnerable regions to climate change worldwide. Since early-season drought limits crop germination, and hence growth, ultimately yield during rain-fed depending on production is commonly experienced nowadays in Mali. Germination and establishment of key crops such as the staple sorghum could be improved by seed priming. The effects of hydro-priming with different water sources (e.g., distilled, tap, rain, river, well water) were evaluated respectively for three priming time durations in tepid e.g., at 25 °C (4, 8, and 12 h) and by hot water at 70 °C (in contrast to 10, 20, and 30 min.) in 2014 and 2015. Seed germination and seedling development of nine sorghum genotypes were monitored. Compared to non-primed seed treatments, hydro-priming significantly [p = 0.01] improved final germination percentage, germination rate index, total seedling length, root length, root vigor index, shoot length, and seedling dry weight. The priming with water from wells and rivers resulted in significant higher seed germination (85%) and seedling development, compared to the three other sources of water. Seed germination rate, uniformity, and speed were enhanced by hydro-priming also. It is argued that hydro-priming is a safe and simple method that effectively improve seed germination and seedling development of sorghum. If used in crop fields, the above most promising genotypes may contribute to managing early season drought and avoid failure of seed germination and crop failure in high climate variability contexts.

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.

Experimental Runs

A study was conducted to determine how seedling development stage at transplanting from plug flats into small pots affected growth and flowering of two commonly grown bedding plants. Seeds of Showstar® medallion flower and ‘Las Vegas Pink’ globe amaranth were sown in 392-cell flats on five dates for each of two experimental runs before transplanting into 8.9 cm (3.5 in) cubic pots. At transplanting of both species, plant height, node count and shoot dry weight increased as days from sowing to transplanting increased and there was no visible cessation in shoot growth due to root restriction. Time to first flower from transplanting decreased linearly with both species in both runs, except with medallion flower in the second run, as time from sowing to transplanting increased. In contrast, time to flower of both species from sowing increased linearly as time from sowing to transplanting increased. However, the magnitude of the increase or decrease in time to flower differed between the two runs indicating that other factors, most likely light intensity and duration, besides node counts were affecting time to flower. Globe amaranth height and growth index and medallion flower growth index at first flower decreased as time from sowing to transplanting increased, whereas medallion flower height was not affected by time from sowing to transplanting.
