- Abstract:
- ... During greening, excised etiolated barley leaves and cucumber cotyledons that were depleted of exogenous Ca²⁺ by a chelating agent (ethylene glycol-bis (beta aminoethyl ether)-N,N,N`N`-tetraacetic acid, EGTA) showed ∼50% reduced chlorophyll (Chl) accumulation and ∼30% accumulation of apoprotein of the light-harvesting chlorophyll a/b-binding protein complex of photosystem II (LHCPII). The Ca²⁺ cha ...

- Abstract:
- ... The effect of feeding by the grain aphid Sitobion avenae (Fabricius) (Homoptera: Aphididae) on chlorophyll, carotenoid and flavonoid content was studied in waxy and waxless triticale genotypes. On both sampling dates (5 and 10 days after infestation), seedlings of infested waxy and waxless plants had lower chlorophylls and carotenoids and higher flavonoids than in uninfested plants. ...

- Abstract:
- ... Cucumber (Cucumis sativus L. cv. Dar) leaves exposed to UV-B irradiation at a biologically effective dose of 9.5 kJ m⁻²d⁻¹ showed decreased chlorophyll fluorescence parameter values versus the control; in peppermint (Mentha piperita L. cv. Asia) leaves those values were almost unchanged after treatment. Fᵥ/Fₒ and Rfd were reduced more than other values, indicating inhibition of the oxygen-evolving ...

- Abstract:

In order to evaluate morphological and physiological traits related to drought tolerance and to determine the best criteria for screening and identification of drought-tolerant genotypes, we grew two tolerant genotypes (MCC392, MCC877) and two sensitive genotypes (MCC68, MCC448) of chickpea under drought stress (25% field capacity) and control (100% field capacity) conditions and assessed the effe ...

- Abstract:
- ... A chlorophyll fluorescence technique enabled early detection of disturbances in the activity of the photosynthet-ic apparatus under Phoma lingam infection. The photosynthetic apparatus of leaves and cotyledons exhibited a negative response to P. lingam inoculation. The effect disappeared more rapidly in leaves, which were not inoculated directly, than in cotyledons, which were inoculated directly. ...

- Abstract:
- ... Conditioned medium (CM) is a general term describing media in which cells have already been cultivated for some time. Such media, usually clarified by filtration, have been used by plant biotechnologists as additives sup-porting the growth of cell suspensions, organs and whole plants. This study examined the effect of CM obtained from green alga Desmodesmus subspicatus on the growth and functionin ...

We investigated the antioxidant defense mechanism, metal uptake and lipid peroxidation (LPO) levels at different leaf positions in Mentha piperita L. grown in Mn²⁺-deficient and control conditions. Under manganese deficiency the activity of superoxide dismutase (SOD), catalase (CAT) and guaiacol peroxidase (GuaPOX) and the content of ascorbate, chlorophyll, and carotenoid under Mn²⁺ deficiency wer ...

- Abstract:
- ... The flowers of Polemonium caeruleum are protandrous. The nectary is in the form of a rim encircling the ovary. Secreted nectar accumulates in a chamber located at the bottom of the floral tube and is protected by dense staminal hairs. The nectary tissue is not vascularized, but is supplied by vascular strands that occur near the base of the nectary and which directly supply the stamens. Nectar is ...

We tested autumn frost hardiness in three Norway spruce (Picea abies [L.] Karst.) provenances originating from different altitudes at two trial plots in Slovakia (Vel'ký Lom at 450 m a.s.l., Mútne-Zákamenné at 1,250 m a.s.l.) in a spinoff experiment of the IUFRO 1964/68 Inventory Provenance Experiment with Norway spruce. Two approaches were used to assess hardiness: the electrolyte-leakage method ...

- Abstract:
- ... MicroRNA miR408 is predicted to target the transcripts for the copper proteins plantacyanin and laccase in Arabidopsis. In this study it was found that miR408 is present in tobacco also. Its accumulation was positively induced by copper deficiency, providing additional evidence for the important role of miR408 in plant responses to nutriment conditions. To examine the functions of miR408 in tobacc ...

- Abstract:

We determined the chlorophyll a and b levels (SPAD readings) in uninfested leaves and in leaves after 7 and 17 days of aphid infestation in four Fabaceae species (Pisum sativum L., Vicia faba L., Trifolium pretense L, Medicago sativa L.). Feeding by pea aphids Acyrthosiphon pisum Harris (Hemiptera: Aphididae) caused significant loss of chlorophyll a and b in the infested plants. Uninfested leaves ...

- Abstract:
- ... Girdling was applied to 5-year-old potted beech individuals of early, intermediate and late phenological forms to block assimilate export from leaves. Phloem severance caused accumulation of soluble carbohydrates and starch in leaves and increased the C/N ratio. While the hexose content increased continuously until the end of the experiment, the sucrose and starch contents peaked earlier, dependin ...
