Milk thistle is a medicinal plant with high pharmaceutical properties to help relief of liver diseases. In this study, the effects of ultrasonic assisted seeds priming (20, 40, 80 and 160 s) with a frequency of 24 kHz and Power of 400 W was investigated on seed enhancement of aged seeds of Milk thistle. Results of the study, showed that as the aging damages increased, the longer sonication results in the better germination. Root growth was significantly improved using ultrasonic energy. Seeds aged for 24 hours, were exposed to ultrasonic produced for 20 seconds exhibited root length of 10.39 cm which was 5.48 cm with no ultrasonic treatment with the same aging duration. The maximum malondialdehyde activity was observed at the 96-hour aging treatment (87.83 nmol/grFW) while the lowest activity was observed at no aged and 24-hour aged seeds (7.28 nmol/grFW). It is suggested that there is a negative correlation between seedling vigor and MAD activity. It was revealed that fatty acid composition of Silybum marianum seed oil is highly influenced by the aging treatment. The variations of unsaturated fatty acids significantly increased in aged seeds. Our results showed that under accelerated aging conditions, ultrasonic assisted seed priming could not provide satisfactory enhancement to seed germination while no aged seeds germination was significantly improved using ultrasonic assisted seed priming.

    One of the effects of reducing water content on soil is reduction of growth and development of seedlings and variation of field development. Seed priming technique has been known as a challenge to improve germination and seedling emergence under different environmental stresses. The objectives of this research were to evaluate the effects of osmo-priming on germination characteristics and changes of proline, protein and catalase activity of Ocimum basilicum seeds. Results showed that drought stress reduced the germination characteristics and drought stress in -8 bar was the critical stress.  Priming treatments were include KNO3, PEG and NaCl by 0, -4 and -8 bar concentrations. The seeds were primed with those materials for 8 and 16 hours. The highest germination characteristics were obtained from nitrate potassium in -8 bar for 16 hours priming. Therefore the best seed treatment under drought stress during germination was obtained from the osmo-primed with -8 bar nitrate potassium for 16 hours. The drought stress increased proline and catalase activity but reduced total protein. Priming treatment increases proline, total protein and catalase activity under drought and control conditions. It is concluded that priming results in improvement in germination components of Ocimum basilicum in drought stress conditions and increases the resistance to drought stress with improvement of proline, protein and catalase activity in germination phase.

Milk thistle is grown in the Czech Republic as a medicinal herb; silymarin is isolated from its achenes and used for the production of liver and gallbladder medicine. The quality and content of the active compound is influenced not only by environmental factors, but also by pests and pathogens. The occurrence of pests of milk thistle variety Silyb was observed in two localities during the years 2011 2013. In the year 2011 the mycoflora of seeds of four milk thistle varieties was determined. Representatives of 15 species were isolated from the seeds, most of them saprophytic. 21 fungal species were isolated and identified from milk thistle plants during the vegetation; Septoria silybi among the most important ones. Possibilities of protection of milt thistle against pathogens are discussed.

Salinity Levels

Milk thistle (Silybum marianum) is used as a medicinal plant in the treatment of liver diseases. In order to investigate germination and seedling growth in S. marianum subjected to NaCl, a three replicated experiment was carried out in a randomized complete block design in the laboratory of Gorgan University of Agricultural Sciences and Natural Resources. Treatments included seven salinity levels (50, 75, 100, 125, 150, 175 and 200 mM) and a control (distilled water). Germination percentage (GP), mean germination time (MGT), seed-ling vigour index (SVI), shoot, root and seedling weight were measured. The effect of salinity levels was significant on GP, SVI, MGT and seedling weight and length (p ≤ 0.01). However, the NaCl concentration effect was not significant on shoot : root length ratio and or shoot : root weight ratios. Results showed that germination decreased when salinity increased, while MGT increased. MGT was 1.75 times higher than in the control at the highest salt concentration. MGT difference was not significant between 75 mM NaCl and con-trol, while it dramatically increased by increasing the NaCl concentration from 150 to 200 mM NaCl. Reduc-tion slope and salt tolerance index (STI) were estimated for germination (0.54 and 231.9) and seedling stage (0.24 and 237.4). According to the results, milk thistle could be considered as a valuable medicinal plant in fairly salinized areas.

Milk thistle (Silybum marianum (L.) Gaertn) has been used in medicine since ancient times, but it has been cultivated as a medicinal plant only in recent decades. The ripe fruit of milk thistle contains flavonoids, which are used to prepare anti-hepatotoxic drugs. The main purpose of this study was to substantiate the effects of irrigation and row spacing on growth, seed yield and the content of active substances (silybin and silymarin) in milk thistle. The results showed that the suitable amount of irrigation was 20 mm and the appropriate row spacing was 25 cm.
