Opis:
Lemon balm (Melissa officinalis L.) is a widely cultivated plant in Europe. Septoria melissae Desm. is the most important pathogen of lemon balm crops, which may cause serious yield loss by the severe leaf fall. As chemical control of the pathogen is restricted, alternative plant protection methods, like the use of tolerant varieties, should be taken under consideration. The goal of our work was to evaluate the susceptibility of three lemon balm varieties to Septoria leaf spot in field. The trials were carried out in 2016 and 2017 in Budapest-Soroksár, Hungary. Dynamics of infection showed characteristic sharp increase from the beginning of August in both years. The lowest infection levels were observed in cultivar ‘Lemona’. The disease incidence in the middle of August was 19% in the first year and 59% in the second year, while these values were over 40% and 70% in the other cultivars ‘Soroksári’ and ‘Quedlinburger Niederliegende’, respectively. The manifestation of symptomps was also significantly lighter on the ‘Lemona’ plants and they had the highest ratio of healthy leaves (81%) compared to the other cultivars. According to the data, weather conditions might modify the range of the differences among the cultivars. It was concluded that appropriate selection of varieties could be an effective and enviromental friendly plant protection method in the practice of lemon balm cultivation.

Opis:
Root-knot nematodes have become a grave menace to the lucrative production of cucumber throughout the world. These nematodes are mainly controlled by applying nematicides, but their use is often associated with hazards. Alternatively, the use of nematode resistant cultivars is considered to be innocuous and economically feasible. For their fitness as nematode-suppressive crops, the reduction in growth and yield parameters of these cultivars must be assessed. As there is little documented data about the effects of Meloidogyne incognita on the damage of cucumber, therefore, in the present study, the effects of M. incognita were evaluated on growth and yield parameters of fifteen cucumber cultivars. M. incognita significantly negatively affected the growth and yield parameters of all the cucumber cultivars. Shoot and root lengths and shoot weights of all the cultivars were significantly reduced as a result of nematode infection. Maximum reductions in these parameters were recorded in highly susceptible cultivars followed by susceptible ones, while the reductions were minimal in resistant followed by moderately resistant cultivars. On the contrary, the infection by M. incognita resulted in an increase in root weights of all the cultivars. The increase was found to be the maximum in highly susceptible cultivars followed by susceptible and moderately susceptible cultivars. Likewise, the minimum increase was observed in the resistant cultivars followed by moderately resistant cultivars. Similarly, significant variations in yield parameters among fifteen cucumber cultivars were also recorded as a result of M. incognita infection. In the case of highly susceptible cultivars, the reductions in yield parameters were maximum, whereas the reductions in resistant and moderately resistant cultivars were found to be minimum. As cultivars Long Green, Marketmore, Pioneer-II, Dynasty and Summer Green experienced no significant damage compared to susceptible cucumber cultivars and therefore, they are approved for cultivation in nematode infested soils.

Opis:
Zinnia elegans is an annual plant recommended for cultivation for cut flowers as well as flowerbeds. This ornamental plant can be infected by: viruses, bacteria, phytoplasms and by a number of fungi species. Presented studies were conducted in 2006 in three localities of the Lublin region: in the vicinity of Zamość, near Krasnystaw and near Opole Lubelskie. Those studies included three cultivars of Zinnia elegans Jacq.: Golden Dawn, Lawa, Scarlet Flame as well as the mixed material of the cultivars belonging to the dahlia group. Six weeks after the sowing, the seedling’s healthiness was assessed. The proportion of seedlings with disease symptoms ranged from 7% to 44%. The main cause of root infection at the seedling stage proved to be the species of F. equiseti and S. sclerotiorum. Considerable amounts of B. cinerea and F. culmorum and A. alternata were also detected from diseased seedlings. Studies on the susceptibility of analyzed cultivars and the mixed material of elegans zinnia to infection by B. cinerea and F. avenaceum F. culmorum and F. equiseti were conducted in a growth chamber. Results obtained from this experiment confirmed considerable harmfulness of the species B. cinera and F. equiseti towards the seedlings of elegans zinnia, which can be reduced introducing less susceptible varieties to the cultivation. However, none of the studied varieties of elegans zinnia, only its mixed material, showed such properties.
Zinnia elegans polecana jest głównie do uprawy na kwiat cięty oraz na rabatach. Ta roślina ozdobna porażana jest przez: wirusy, bakterie, fitoplazmy i różne gatunki grzybów. Prezentowane badania przeprowadzono w 2006 r. w trzech lokalizacjach woj. lubelskiego: w okolicach Zamościa, w okolicach Krasnegostawu i w okolicach Opola Lubelskiego. Objęto nimi 3 odmiany cynii wytwornej (Golden Dawn, Lawa, Scarlet Flame) należące do grupy daliowatych oraz materiał mieszany odmian. Po 6 tygodniach od wysiewu przeprowadzono ocenę zdrowotności siewek. Udział siewek z objawami chorobowymi wahał się od 7 do 44%. Główną przyczyną porażenia korzeni w stadium siewki okazały się gatunki F. equiseti i S. sclerotiorum. Z chorych siewek w znacznych ilościach uzyskiwano także B. cinerea i F. culmorum oraz A. alternata. Badania podatności siewek analizowanych odmian i materiału mieszanego cynii wytwornej na porażenie przez B. cinerea oraz F. avenaceum, F. culmorum i F. equiseti przeprowadzono w fitotronie. Uzyskane wyniki potwierdziły szczególnie dużą szkodliwość dla siewek cynii wytwornej gatunków B. cinera i F. equiseti, którą można zmniejszyć wprowadzając do uprawy odmiany mniej podatne, jednak takiej właściwości nie wykazywała żadna z badanych odmian cynii wytwornej, jedynie materiał mieszany odmian.
