    Lead (Pb) is the most common heavy metal pollutant in the environment. The objective of the presented study was to investigate the ameliorative effect of exogenous 1 mM ASA on key growth and biochemical parameters in Lycium barbarum seedlings under heavy metal (Pb(NO3)2) stress in vitro. Nodal cutting with an axillaries bud were used as an explants. The results showed that lead accumulation in goji explants had negative influence on morphological parameters of plant growth, such as shoot and root length. Lead caused a significant reduction in chlorophylls and carotenoid content, increased lipid peroxidation and induced significant accumulation of proline in goji leaves. Addition to MS medium 1 mM ASA greatly alleviated Pb-induced growth inhibition and Pb-induced MDA and proline accumulation. Presence of ASA in the MS medium under heavy metal stress increased plant fresh and dry mass with no significant effect on plant water content.

    The effectiveness of disinfection methods on germination of goji seeds (Lycium barbarum L.) in in vitro culture
    (Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2017) Kruczek, Arleta; Krupa-Małkiewicz, Marcelina; Ochmian, Ireneusz; Department of Horticulture, West Pomeranian University of Technology, Szczecin; Department of Plant Genetics, Breeding and Biotechnology, West Pomeranian University of Technology, Szczecin; Department of Horticulture, West Pomeranian University of Technology, Szczecin
    Using disinfectant components is one of main ways to control of fungal and bacterial contaminations in the in vitro culture. Alternative to commonly used chemicals is ozonation. The present study was focused on the efficiency of seeds disinfection of two goji cultivars ‘A’ and ‘New Big’ using eight different treatments, 7%, 10% and 15% NaOCl and 0.2% HgCl2 for 15 minutes each, O3 gas and O3 in water for 5 and 15 minutes. The highest percentage of germinated seeds of ‘A’ and ‘New Big’ (respectively 62% and 78%) with the lowest number of infections (respectively 8% and 14%) was obtained after using 7% NaOCl solution. Less effective was 0.2% HgCl2 solution, where the percentage of germinated seeds of ‘A’ and ‘New Big’ was lower (respectively 37% and 30%). However, after O3 in water treatment of goji ‘A’ and ‘New Big’ for 15 minutes the percentage of germinated seeds was the highest (respectively 47%, and 53%) and sterility of the cultures of goji ‘A’ was 100%. In addition to, the ozonation of the seeds showed similar disinfection efficiency, as with 15% NaOCl solution. Therefore, ozone gas makes an alternative for commonly used disinfectants.

    The influence of shurbs cutting method on yielding and quality of the goji berries (Lycium barbarum L.)
    (Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2016) Kruczek, Arleta; Ochmian, Ireneusz; Department of Horticulture, West Pomeranian University of Technology, Szczecin; Department of Horticulture, West Pomeranian University of Technology, Szczecin
    In the experiment were compared: the growth of shrubs, yielding, the physical parameters of fruits and their chemical composition depending on the method of cutting bushes – the amount of main shoots. Research material consisted of goji berries grown in Department of Horticulture Research Station of the West Pomeranian University of Technology in Szczecin. Goji berries (Lycium barbarum L.) are characterized by high potential of health promoting properties and nutritious. They have been extremely important part of traditional Chinese medicine for ages. They are used there as a very important part of a healthy diet, due to the appearance of the complex polysaccharide valuable LBP (Lycium Barbarum Polysaccharides). Cutting of shoots stimulated growth of shrubs. Bushes cut into 3 shoots grew with larger number of shorter basal shoots, while the one-year shoots were the longest. The leaves of the cut bush were darker (L* = 39.8 and 41.2) and had a higher green index (42.1 and 44.8), in comparison to uncut bushes (L* = 37.3, SPAD = 43.5). It was also found that there is a significant correlation between the green index and the value of the parameter a* (r* = 0.92). Cutting of shrubs, especially into 3 shoots, reduced yielding however influenced increasing the size of the fruit.
