Solidago canadensis L. is an expansive perennial that forms persistent, species-poor plant communities. It often spreads in fallow areas, displacing native floristic ingredients. Its expansiveness is largely due to morphological features, but it can also be the effect of allelopathic interaction. The aim of the experiment was to investigate the effect of aqueous extracts (decoction, infusion, and maceration) from dry S. canadensis leaves on germination and early growth stages of Raphanus sativus L. var. radicula Pers., in three cultivars: ‘Rowa’, ‘Półdługa’, and ‘Krakowianka’. In comparison to the control, the percentage of germinated radish seeds of ‘Rowa’ cultivar was statistically lower on the infusion and macerate. Regardless of the cultivar, the smallest changes in germination were found in seeds watered with decoction, and the largest with macerate. Seedlings length was most inhibited on macerate substrates, and least with infusion. Regardless of the form of the extract, each of them negatively affected the initial growth of radish seedlings. A fresh mass of ‘Rowa’ seedlings was inhibited by all Canadian goldenrod extracts. In relation to the control, the ‘Krakowianka’ cultivar was the least sensitive to S. canadensis extracts. The total chlorophyll content was the lowest in the seedlings of the ‘Rowa’ and ‘Półdługa’ cultivars germinated on macerate, compared to the control and two others extracts. The percentage of electrolyte leakage depended on the type of extract used and the radish cultivar. The study showed that depending on the cultivar, the aqueous extracts from S. canadensis leaves decreasing of germination and early growth of R. sativus.

The conducted experiment was aimed at determining the effect of aqueous extracts from dry roots and shoots of common weed nipplewort (Lapsana communis L. subsp. communis) on seeds germination and early growth of radish (Raphanus sativus L. var. radicula Pers.), cultivars ‘Rowa’, ‘Krakowianka’, ‘Półdługa’. The experiment was carried out in the form of Petri dishes tests with 3 different percentage concentrations of extracts (1%, 3% and 5%, respectively). The germination indexes used here revealed that the germination capacity of the radish seeds was significantly inhibited by extracts from the roots and shoots of L. communis subsp. communis. The elongation growth of radish roots and hypocotyls was stimulated to a higher percentage by extracts from nipplewort roots than by extracts from shoots. The fresh and dry mass of the radish seedlings depended on the type (roots/shoots) and concentration of the extract as well as the radish cultivar. The electrolyte leakage was the highest in seedlings watered with 5% extract of nipplewort shoots. The cultivar most sensitive to nipplewort extracts turned out to be ‘Półdługa’, and the least sensitive was ‘Rowa’. The response of radish seeds to nipplewort extracts is probably due to the presence of allelochemical compounds and their synergistic interaction.

In this paper, effect of halopriming on germination, initial growth and development of radish under salt stress conditions was investigated. The seeds were treated with different concentrations salts of calcium, potassium, and sodium chloride (CaCl2, KCl, NaCl, respectively) in the form of a standard germination method and priming method, which involves modification of the metabolic activity of seeds in the pregerminative phase. The obtained results showed that all applied salts had inhibitory effects on germination characteristics (GP, RG and U, except MTG) and development of radish seedlings (shoot and root elongation, weight and vigour). Halopriming contributed to the improvement of tolerance to stress conditions, because the obtained values of all germination and growth characteristics were significantly increased. The best effect being achieved by priming with CaCl2 for germination characteristics and vigour and with KCl for initial development.

ABSTRACT The use of plants with allelopathic activity nowadays is very important because it allows us to develop a profitable agriculture and non-polluting the environment. The objective of this work was to study the action of aqueous extracts of garlic (Allium sativum L, Liliaceae), avocado (Persea americana Mill, Lauraceae) and rough (Ruta graveolens L, Rutaceae) on the development of vegetable radish (Raphanus sativus L, Brassicaceae). The extracts were prepared from A. sativum bulbs, P. americana seeds and R. graveolens leaves and flowers to which he adds crushed boiled water. Treatments were the pure extracts (20% w / v). The design was completely randomized with 4 repetitions. It was found fresh weight (g), dry weight (g), root length (cm) long area (cm) and leaf area (cm2 ). The data was analyzed with Anova and Tukey test for the comparison of averages. The results show that there is no significant effects compared to the control of allelopathic potential of aqueous extracts tested under controlled conditions. Keywords: Aqueous extracts, seed, leaves, flowers, bulbs, Allium sativum, Persea americana, Ruta graveolens.

The current paper presents the results of a study on the effects of aqueous extracts from five weed species (Amaranthus retroflexus, Cirsium arvense, Convolvulus arvensis, Echinochloa crus-galii, Setaria verticillata) on germination and initial growth in Raphanus sativus L. The following indicators have been analyzed: indices of germination (the germination percentage; the speed of germination; the speed of accumulated germination and the coefficient of germination rate), the length of the root and hypocotyls, the pH of aqueous extracts, the UV-Vis absorption spectra of aqueous extracts. The results of the investigations showed the following aspects: the aqueous extracts reduced the values of calculated germination indices and root growth in the first ontogenetic stages of the test species; the pH of the extracts was slightly acid to neutral. Qualitative spectrophotometric analysis indicated the possible presence of phenolic and organic compounds in the extracts. C. arvense, S. verticillata and E. crus-galii presented the most pronounced effect on germination and growth processes.

The aim of this study was to investigate the effect of aqueous extracts from Chenopodium album L. on germination and early stages of triticale grains (×Triticosecale Wittm. ex A.Camus) and radish seeds (Raphanus sativus L.). Germination indexes, fresh and dry mass, water content and electrolyte leakage were measured. Studies revealed the different germination capacity of triticale grains and radish seeds, where increased concentrations of allelopathins in aqueous C. album extracts significantly inhibited seedling growth for both species. The extracts had an inhibitory effect on the growth of seedling fresh mass. An increase in dry mass of radish seedlings was demonstrated for each of the extracts and, for triticale seedlings, only at concentrations of 0.5% and 1.5%. Water content in triticale and radish seedlings varied depending on the concentration of allelopathins in the extract. With increasing concentrations of C. album extract, regardless of seedling type, a statistically significant increase in electrolyte leakage was observed.
