BENADA J. (1990): Less common symptoms of cereal diseases by two parasitic fungi. Česká Mykologie 44(4): 243 (published: 26th November, 1990)
abstract
Two unusual symptoms of cereal diseases caused by Ustilago nuda and Puccinia persistens var. triticina are described. U. nuda formed smut sori on barley leaf blades instead of ears. P. persistens developed uredia in a ring pattern on wheat leaves transferred to a glasshouse.
KLÁN J., ŘANDA Z., BENADA J., HORYNA J. (1988): Investigation of non-radioactive Rb, Cs, and radiocaesium in higher fungi. Česká Mykologie 42(3): 158-169 (published: 12th August, 1988)
abstract
The concentration factors for non-radioactive Rb, Cs, and radiocaesium in the fruit bodies of mushrooms were determined. The difference between the concentration factors of non-radioactive and radioactive Cs from the last fallout was one order of magnitude. No significant differences were found between the concentration factors of stable Rb and Cs for mushrooms and vascular plants. The highest accumulation of radiocaesium was observed in Boletus spp., Laccaria spp., Paxillus involutus, Cortinarius armillatus, and Lactarius rufus. The contribution of older weapon-test fallout and the more recent 1986 Chernobyl fallout could be differentiated by isotopic ratio. The radiation dose from consumption of 10 kg fresh mushrooms did not exceed 20% of the dose from natural background radiation in Czechoslovakia.
BENADA J. (1974): The susceptibility and the resistance of the tissues of cucumber and squash to powdery mildew Sphaerotheca fuliginea in the dependence on oxidation reduction potencial and pH. Česká Mykologie 28(1): 44-53 (published: 1974)
abstract
The resistance of cucumber and squash to powdery mildew (Sphaerotheca fuliginea) was estimated based on conidia germination and mycelium formation on detached leaves kept on moist filter paper under high humidity. No direct relationship was found between oxidation-reduction potential (ORP), pH, and susceptibility. However, two susceptibility zones were identified: cotyledons with pH ~6 and ORP ~+50 mV, and older leaves with pH ≥7 and negative ORP. Similar results were found in squash tissues.
BENADA J. (1967): The dependence on the pH of the host tissue for the production of Uredia and Telia in Uramyces pisi (Pers.) de Bary. Česká Mykologie 21(2): 90-91 (published: 1967)
abstract
The production of uredia and telia in Uromyces pisi is shown to depend on the pH of the host tissue. Uredia and telia develop in tissues with pH above and below 6.3–6.5 respectively, confirming previous findings in cereal rusts and extending them to dicotyledons.
