Opis:: Fungistatic activity of seed extracts from Heracleum Sosnowskyi, Levisticum officinale and Aegopodium podagraria was investigated. The extract from H. Sosnowskyi at concentrations 0.5–1.5 cm3 100 cm–3 highly inhibited the growth of fungi colonies of Fusarium culmorum and Botrytis cinerea while a seed extract from A. podagraria exhibited no fungistatic activity. The spraying of rose and bean leaves with extracts from H. Sosnowskyi and A. podagraria substantially reduced necroses caused by Botrytis cinerea. Under field conditions the extracts from H. Sosnowskyi and A. podagraria effectively decreased the infestation of azalea leaves with Microsphaera penicillata.
Badano aktywność fungistatyczną ekstraktów z nasion roślin selerowatych: Heracleum Sosnowskyi, Levisticum officinale i Aegopodium podagraria. Wyciąg z H. Sosnowskyi w stężeniach 0,5-1,5 cm3 100 cm -3 silnie hamował wzrost kolonii grzybów Fusarium culmorum i Botrytis cinerea, natomiast wyciąg z nasion A. podagraria nie wykazywał aktywności fungistatycznej. Opryskanie liści róży i fasoli wyciągami H. Sosnowskyi i A. podagraria znacznie ograniczało powstawanie nekroz powodowanych przez Botrytis cinerea. W warunkach polowych wyciągi H. Sosnowskyi i A. podagraria skutecznie zmniejszały porażenie azalii wielkokwiatowej przez Microsphaera penicullata.

Opis:: Chemical (weight loss and thermometric) measurements were used to study the corrosion inhibition characteristics of five seed shells, namely Afzelia africana seed shell (AASS), Brachystegia eurycoma seed shell (BESS), Derium microcarpum seed shell (DMSS), Mucuna flagellipes seed shell (MFSS) and Pentaclethra macrophlla seed shell (PMSS), respectively, on the inhibition of aluminum corrosion in aggressive 2.0 % HCl solutions at 30 and 50 °C for 8 hrs. Weight loss and thermometric measurements demonstrated that the seed shells (AASS, BESS, DMSS, MFSS and PMSS extracts) act as good corrosion inhibitors. Addition of the seed shell extracts decreases the corrosion rate of the process thereby improving inhibition performance. The result also reveals that the five seed shell extracts adsorb on the Aluminum surface through physical adsorption in accordance with Flory-Huggins and Langmuir adsorption isotherms at all temperatures investigated. Kinetic-thermodynamic parameters indicate a spontaneous adsorption process. Results of inhibition efficiency demonstrates that DMSS extract performed better as compared to BESS, AASS, PMSS and MFSS extracts.

Tytuł:: Reaction of soybean varieties to natural water extracts in different method of their application

Opis:: The subject of the following study is the reaction of six varieties of soybeans (Glycine max L. Merr.): Abelina, Augusta, Merlin, Mavka, Aligaor, Lisabon, on an aqueous decoction of dried Artemisia absinthium L. used as wet seed treatment. The experiment was carried out in a greenhouse belonging to the Experimental Station for Variety Testing in Karzniczka. Two combinations of the extract were used: 24h soaking of seeds in the decoction followed by sowing and soaking in distilled water followed by sowing, but untreated seeds with simultaneous dosing of herbal extract. The control group were seeds not treated with preparations. After sixteen days of the test, the average number of plant growth was determined for each experimental combination. The morphological characteristics of the seedlings: length of shoots and roots as well as fresh and dry mass of shoots and roots were evaluated for ten randomly selected plants from each experimental combination. The results of the greenhouse experiment showed different reaction to the application of the decoction in the form of a seed treatment. Soil application of the extract led to the improvement of soybean growth. Seedlings of all varieties, the seeds of which were treated and sown, developed a longer and stronger root system at the expense of a slight reduction in the length and weight of the shoots. The 24h soaking of seeds in the decoction of Artemisia absinthium caused the deterioration of emergence and the visible inhibition of the growth and development of soybean seedlings. The inhibition of germination and emergence by the tested extract excludes the possibility of agricultural application. Further research is needed to identify the bioactive compounds contained in the used decoction and to assess the real effectiveness of the soil application of the extracts under field conditions.
