The Impact

Introduction. Marigold (Calendula officinalis L.) is an annual plants belongs to Asteraceae family. The species is widespread in the world and have a long tradition of medicinal use with multidirectional action. Aim. The field experiments were carried out to assess the impact of genetic (cultivar) and environmental factors on yielding variability and biosynthesis of essential oil in conditions of conventional cultivation of marigold after using different methods of plantation weeding. Material and methods. The research material were two cultivars of marigold such as Orange King and Indian Prince. The following activity were tested: 1) spraying of Fusilade Forte 150 EC (1 l • ha-1), 2) spraying Fusilade Forte 150 EC (1 l • ha-1) + manual weeding, 3) manual weeding, 4) no weeding – control. The scope of the research included assessment of marigold yield (inflorescence) and determination of the essential oil contents in dry mass of raw material. Results. Regardless of the cultivar, a non-chemical methods (mechanical weeding in interrows and manual in rows) gave the highest efficiency of weed control. Similar results observed after using chemical weeding with manual weeding. In these cases the yields were at least 2.5 times higher than obtained from the control. The total yield of dry mass of inflorescence for the above methods was 6.35 and 5.53 q • ha-1 for Orange King cultivars, slightly lower result obtained for cultivar of Indian Prince (4.81 and 4.12 q • ha-1). It was also shown that the content of essential oil in the raw material ranged from 0.25 to 0.37% and was independent from the cultivar. Conclusions. The Orange King cultivar of marigold yielded better than Indian Prince in analogous methods of plantation weeding. The highest effectiveness of weed plantation was found using a non-chemical method (mechanical weeding in interrows and manual weeding in rows) and using chemical weeding with manual weeding. It was shown that the content of essential oil in the inflorescences of both examined cultivars was similar.

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.

Harmful Effects

<p>Salt stress is one of the most important factors limiting the growth and yield of plants around the world. However, silicon can reduce the harmful effects of salt stress on plants. For this purpose, an experiment was conducted in a factorial arrangement on randomized complete block design with three replications in a research greenhouse on the Satureja hortensis medicinal plant. Experimental treatments consisted of two salinity levels (control and 100 mM) and potassium silicate (Si) at three levels (0, 1, and 2 mM). The results showed that salinity reduced shoot dry weight, photosynthetic pigments and potassium content of shoot. However, sodium, proline, MDA, and H2O2 contents in shoot increased. The highest shoot dry weight, photosynthetic pigment content, proline, RWC, and the lowest content of MDA and H2O2 of the shoot were observed with Si application under salt stress and non-salt stress conditions. The highest yield of essential oil was also observed with Si application under salt stress and non-salt stress conditions. Therefore, the use of silicon in salt stress condition not only minimizes the harmful effects of salt stress by increasing the K+/Na+ ratio and improving the morphological and physiological traits of the Satureja hortensis medicinal plant but also improves the essential oil yield of this medicinal plant in salt stress and non-salt stress conditions.</p>

During our research we investigated the marigold's (Calendula officinalis L.) nutrient requirements with different fertilization setting in small-plot trial. We measured SPME (Solid phase microextraction) and GC-MS (gas chromatograph-mass spectrometer) we examined the effects of the different fertilization settings for the herb's main active ingredients of essential oil's percentage. Based on the results, it was concluded, the essential oil agents' percentage breakdowns significantly depending on the cropping technologies. Besides that it is possible, based on Pearson's correlation test the marigold essential oil agents relationship can also be a major factor.
