Studies on the Morphine * Content of Papaver somniferum L

Abstract The present paper investigates the variation of the morphine content related to the vegetation stages on Papaver somniferum L, cultivated at Braşov. The study stresses the importance of creating specific poppy cultures for morphine cultures harvested in a stage of immature capsules when the content of morphine and the morphine yield per hectare increase three times. The study also indicates that research in this field led to the creation of a new poppy variety (Safir) with superior morphine content (0.63 g/100 g shells). This variety can be used in seed production for growing cultures used in the production of morphine

STUDIES REGARDING THE EFFECTS OF Rosmarinus officinalis OIL TREATMENTS IN HEALTHY AND POTATO VIRUS Y (PVY) INFECTED PLANTS Solanum tuberosum L

Abstract. The potato virus Y cause loss in yield and quality of tubers. Hydrogen peroxide, ascorbic acid and antioxidants such as rosmarinic acid present in oils extracted from Rosmarinus officinalis plants are implicated in signaling against stress. The effects of these chemicals on tuber yield and pigments content were evaluated in plants testing positive after virus mechanical infection. Without chemical treatment, positive plants showed significant reductions in leaf pigments content and tuber weights compared to uninfected controls. Hydrogen peroxide, ascorbic acid and oil treatments of PVY infected plants significantly reduced the number of minitubers, enhancing their weights, while leaf pigment content also increased. This research demonstrates potential benefits of treatments with oils extracted from Rosmarinus officinalis plants and hydrogen peroxide or ascorbic acid in enhancing the yield and quality of tubers

Research and Science Today Supplement No. 1/2013

RESEARCH AND SCIENCE TODAY is a biannual science journal established in 2011. The journal is an informational platform that publishes assessment articles and the results of various scientific research carried out by academics. We provide the authors with the opportunity to create and/or perfect their science writing skills. Thus, each issue of the journal (two per year and at least two supplements) will contain professional articles from any academic field, authored by domestic and international academics. The goal of this journal is to pass on relevant information to undergraduate, graduate, and post-graduate students as well as to fellow academics and researchers; the topics covered are unlimited, considering its multi-disciplinary profile. Regarding the national and international visibility of Research and Science Today, it is indexed in over 30 international databases (IDB) and is present in over 200 online libraries and catalogues; therefore, anybody can easily consult the articles featured in each issue by accessing the databases or simply the website
