“…2009). Van Andel (1966) wyjaśniając mechanizm działania aminokwasów na czynniki chorobotwórcze, wskazuje na ich działanie grzybobójcze, obniżenie agresywności (wirulencji) patogenów, produkcję innych związków w glebie lub roślinie, zaburzenia metabolizmu azotu, ingerencję w ekspresję objawów i zwiększenie odporności rośliny na patogeny. W zależności od czynnika chorobotwórczego oraz rośliny gospodarza aminokwasy mogą przyśpieszyć (Booth 1969;Singh i wsp.…”

Possibilities of using products containing amino acids in the protection of roses against Podosphaera pannosa and their influence on plant developmentMożliwość wykorzystania środków zawierających aminokwasy w ochronie róż przed Podosphaera pannosa oraz ich wpływ na rozwój roślin Adam Wojdyła* SummaryThe study assessed the influence of the plant growth promoter Agro-Sorb Folium and foliar fertilizers Agro-Sorb L-Amino and Agro--Sorb Radiculum, used 4 times at 7-day intervals as foliar spray application on roses grown in a greenhouse, on the development of disease symptoms caused by Podosphaera pannosa. Agro-Sorb Folium and Agro-Sorb L-Amino were applied at the concentrations of 0.25, 0.5 and 1%. Their effectiveness ranged from 64 to 98%. An increase in the concentration of the tested products caused an increase in their effectiveness. Agro-Sorb Radiculum used at the concentration of 0.5% showed an effectiveness of about 85%. The fertilizers Agro-Sorb L-amino and Agro-Sorb Radiculum showed an effectiveness of 21.7% and 64%, respectively after a 2-fold watering treatment, and 17% and 10% after a 4-fold applications. All the tested products used as foliar or watering application caused significant stimulation of the growth of rose shrubs. None of the products caused changes in the appearance of roses (phytotoxicity).Key words: Podosphaera pannosa; Rosa sp.; rose; powdery mildew; amino acids; effectiveness StreszczenieOceniano wpływ stymulatora wzrostu roślin Agro-Sorb Folium, nawozów dolistnych Agro-Sorb L-Amino oraz Agro-Sorb Radiculum, stosowanych 4-krotnie co 7 dni do opryskiwania róż uprawianych w szklarni, na rozwój choroby powodowanej przez Podosphaera pannosa. Agro-Sorb Folium oraz Agro-Sorb L-Amino aplikowano w stężeniu 0,25; 0,5 oraz 1%. Ich skuteczność wynosiła od 64 do 98%. Wzrost stężenia badanych środków powodował zwiększenie ich skuteczności. Agro-Sorb Radiculum w stężeniu 0,5%, zastosowany do opryskiwania róż, wykazywał około 85% skuteczności. Nawozy Agro-Sorb L-Amino oraz Agro-Sorb Radiculum po 2-krotnym podlaniu róż wykazywały 21,7% oraz 64% skuteczności, a po 4-krotnym odpowiednio 10% i 17%. Wszystkie badane środki stosowane do opryskiwania lub podlewania powodowały istotną stymulację wzrostu krzewów róż. Żaden z badanych środków nie powodował zmian w wyglądzie róż (fitotoksyczności).Słowa kluczowe: Podosphaera pannosa; Rosa sp.; róża; mączniak prawdziwy; aminokwasy; skuteczność Instytut Ogrodnictwa Konstytucji 3 Maja 1/3,

“…Pautot et al (1993), however, found that the increase in amino acid levels did not appear to be the result of enhanced protein hydrolysis by enzymes such as leucine amino peptidase, an inducible component of the defence response in tomato plants. Van Andel (1966) suggested that amino acids might act indirectly by changing the metabolism of the plant, leading to the production of antifungal substances, or by the activation of other synthetic pathways.…”

“…In the recent past, many experiments have indicated that amino acids may play wide roles in plants including acting as regulatory and signalling molecules (Rai, 2002). The indirect effect of amino acids on the pathogen was reported by Van Andel (1966), who suggested that amino acids could act indirectly by changing the metabolism of the plant, leading to the production of antifungal substances directly from amino acids, or by the activation of other synthetic pathways. One example was the injection of tomato leaves with a variety of amino acids and other substances, which induced resistance to Verticillium dahliae and the synthesis of antifungal compounds (Emmanouil and Wood, 1981).…”

Inoculating wheat (cv. Giza 164) with various Fusarium species had different effects on the catalase (CAT), peroxidase (POX) and ascorbate peroxidase (APX) activity in different plant tissues. The CAT activity induced in the shoots of wheat plants by some pathogens (F. merismoides, F. moniliforme, F. poae and F. sambucinum) was relatively higher than that induced by other pathogens. The results showed an increase in POX activity in infected shoots except those inoculated with F. sambucinum, where the POX activity decreased. Inoculating wheat plants with individual Fusarium species or with a mixture of pathogens caused an increase in APX in the shoots, except for those treated with F. poae, where the APX activity decreased. The activity of these antioxidant enzymes thus increased in most cases in the shoot system of wheat plants under Fusarium infection. Investigations on the metabolic activity of wheat plants inouculated with individual Fusarium species or with a mixture of pathogens showed higher contents of all the protein fractions, soluble sugars, total free amino acids and proline. The K + and Ca 2+concentrations decreased to various extents in different cases. The Na + content increased in wheat shoots, especially after inoculation with F. merismoides. The results signify that the most serious infection was caused by F. culmorum, F. graminearum and F. oxysporum and by a mixture of all the Fusarium species.

Abstract. The exudate production of alfalfa under the conditions of the sterile flow culture was quantitatively measured. In the first 40 days 3.10-3 ,mmoles amino-N, 2.5 ,,uequivailents of organic acids and approximately l04 ,moles of reducing sugars were liberated per plant and per day into the percolating nutrient solution. The amino acid concentration in the outflow varies according to a daily periodicity. The exudation of a colored substance also shows daily periodical variations. This pattern is d6ifferent from the pattern of the amino acid exudation, however, and directly coupled to -shoot illumination. Short-term 2,4-dinitrophen,ol additions to the nutrient lower the liberation of amino acids into the percolating soilution.Much work has been done to learn more about the special conditions and processes which characterize the plant root rhizosphere. Some literature reviews concerning root exudates were published since 1964, considering the more general character (32,33) as well a's the special aspects of the subject (2, 7). Several papers presenting quantitative and semi-(Iuantitative data on exudate production were the background for the experiments and results here to be described.
