Opis:
Identification of cultivars is essential both in breeding and to settle cultivar disputes. The purpose of the study has been to examine cultivar identities based on absorption spectra of plant pigments and to confirm a genetic stability with SCoT and RAPD molecular markers in new Polish lines of Chenopodium quinoa Willd. Spectral analysis of pigments extracted from plant inflorescences in quinoa gives an opportunity to confirm the cultivar identity and identification of ‘Faro’ and ‘Titicaca’ cultivars and their new lines. Spectral analysis is an effective method of confirming cultivar identity and it should be used in practice for the identification of cultivars or cultivars lines in Chenopodium quinoa Willd. Analysis of molecular markers indicated by RAPD as well as SCoT technique revealed a high genetic stability of the derivative lines of ‘Faro’ and ‘Titicaca’, while variation was detected in plants representing original cultivars: banding pattern different than predominant was present in three plants of ‘Titicaca’ (genetic distnaces from 7.5% to 55.9%) and in a single plant of ‘Faro’(genetic distance 61.2% as indicated by SCoT technique).

Opis:
The experiment studied the effect of various mulching terms of ‘Foxtrot’ tulips with wheat straw in combination with spraying of plantations with herbicides using various doses and different amounts of working liquid. The mulch was laid out just after planting and after the soil had frozen. The experiment included combinations, in which the mulch was left until the end of the growing season or removed in spring. Spraying with single (linuron 675 g·ha–1 + lenacyl 1000 g·ha–1) or double herbicide dose (linuron 1350 g·ha–1 + lenacyl 2000 g·ha–1) was made before covering the soil with mulch and also on mulch – two weeks after planting the bulbs, or in the spring after thawing the soil. Volumes of 300 dm3 and 600 dm3 of working liquid were used for spraying. Tulips covered with mulch bloomed 2–3 days later and formed longer shoots as compared to non-mulched ones. The highest yield of marketable bulbs and the first-selection ones was obtained from tulips mulched immediately after planting and sprayed 2 weeks later with herbicides used in a single dose of 600 dm3 of a working liquid. Mulching of tulips after soil freezing and removal of mulch in spring adversely affects the number and weight of commercial bulbs. The lowest yield was obtained in combinations, in which the mulch was not used. The use of additional nitrogen fertilization before laying out the mulch did not affect the yield of tulips. Herbicides can be used both before mulching and after covering the plantation with mulch. It is not necessary to increase the dose of the agent and the amount of water.

Bio-algeen S-90 preparation
Opis:
Striving to intensify horticultural production, new and more effective bio-preparations are being sought to stimulate plant growth and development. Bio-algeen S90 is a natural agent based on sea algae, the high biological activity of which results from the high content of natural growth regulators. The aim of the study was to verify the influence of Bio-algeen S90 on the growth, morphological characteristics and chlorophyll fluorescence of Rosa multiflora seedlings. The bio-preparation was applied one, two and three times at concentrations: 0.1, 0.2, 0.4 and 0.6 mg.dm−3. Following parameters were measured to evaluate the response of plants to the bio-preparation: F0 – initial fluorescence, Fm – maximal fluorescence in the dark-adapted state, Fv/Fm – maximum photochemical efficiency of PSII. All concentrations of the bio-preparation and frequency of its application stimulated the number of shoots in a bush, the length of shoots and the diameter of the root crown of plants intended for budding. The most beneficial was the two-fold bio-preparation application at a concentration of 0.4 mg.dm–3. Bio-algeen also positively influenced the chlorophyll fluorescence parameters. The highest mean F0 and Fm values were recorded with the two-fold preparation treatment. There was no significant effect of the bio-preparation on the Fv/Fm index, which was within the range of 0.75–0.66.

Opis:
One of the ways to reduce the water consumption by plants while maintaining their proper quality is to use substances that limit excessive transpiration. Three preparations at following concentrations: Moisturin (10%), Root-Zone (4.5%) and Vapor Gard (1%), were used in the experiment. Moisturin and Vapor Gard were applied in the form of a single spray, and Root-Zone as a single irrigation in mid July.The aim of the research was to assess the effect of several anti-transpirants on some biometric features of the ‘Tardiva’ panicled hydrangea depending on the frequency of irrigation. The following parameters were measured: area, perimeter, width and length of leaf blade, length and width of inflorescences, and the diameter of shoots. Treatment of H. paniculata cv. ‘Tardiva’ with Root-Zone and Moisturin anti-transpirants with a single irrigation every other day allows to reduce the water consumption and obtain shrubs of a quality comparable with plants irrigated twice a day. The use of Moisturin with a twice daily irrigation positively affected the length and width of inflorescences.

Opis:
Three-year studies (2014–2016) were conducted in Lublin in the south-east Poland. The objects of research were the plants of ten canna cultivars: ‘Aida’, ‘America’, ‘Botanica’, ‘Cherry Red’, ‘La Boheme’, ‘Lucifer’, ‘Picasso’, ‘Robert Kemp’, ‘President’ and ‘Wyoming’. Observations were carried out each year in October. Plants with symptoms of stem and root rot, leaves yellowing and wilt were noticed on the investigated plantations. The plants were studied with regard to photosynthetic activity and also by disease index for all cultivars and statistical analysis was carried out upon them. The effect of disease index on photosynthetic intensity and transpiration was determined after the calculation of Pearson’s correlation coefficient. Infected plants were collected for mycological analysis. The results of mycological analysis showed that canna plants were colonized by Fusarium spp., Sclerotinia spp. and Alternaria spp. Alternaria alternata, Fusarium oxysporum, Fusarium avenaceum and Sclerotinia sclerotiorum predominated among pathogenic species. The best health status and the lowest number of colonies were noticed for plants of cv. ‘Botanica’. The infection of canna leaves by pathogenic fungi has negatively affected the intensity of photosynthesis, transpiration, stomatal conductance and sub-stomatal CO2 concentration and it was largely related to the degree of infestation of specified varieties of canna. The photosynthesis process was limited especially in ‘La Boheme’, ‘Picasso’, ‘Cherry Red’ and ‘President’ cultivars, which were infected most frequently by pathogenic fungi. It was confirmed by negative Pearson’s coefficient.
