Apterous and alate viviparous females of Protaphis kvavadzei sp. n. on Eryngium campestre (Apiaceae) and Aphis matricariae sp. n. on Matricaria sp. (Asteraceae) from Turkey are described. The new species are differentiated from other aphids colonising these host plants and from species with similar morphology.

Mitotic chromosome number of 14 taxa of Bothriochloa native to Argentina, Brazil and Uruguay were surveyed. Chromosome numbers of B. eurylemma, B. meridionalis and B. velutina are reported for the first time, with 2n = 6x = 60, and this ploidy level is the most common among the studied taxa. In addition, new cytotypes were found for B. alta (2n = 60), B. barbinodis (2n = 60), B. exaristata (2n ...

The responses of young plants of diploid and tetraploid Matricaria chamomilla cultivars to abiotic stress were studied. The course of quantitative changes of main leaf secondary metabolites was evaluated within an interval from 6 h before to 54 h after spraying the leaf rosettes with aqueous CuCl2 solution. The content of herniarin in the treated plants rose approximately 3 times, simultaneousl...

Purpose Chamomile is a traditional herb known for its calming effects. We are conducting a long-term, randomized, placebo-substitution study of chamomile for the prevention of recurrent Generalized Anxiety Disorder (GAD) in individuals who have responded to initial, open-label chamomile therapy. We present preliminary results from the trial’s open label phase to offer initial evidence of safety...

Plant habit and production of secondary metabolites in chamomile plants depend on endogenous and exogenous factors that can be divided into two groups (FRANZ 1982): a) morpho-ontogenetic variability, b) genetic variability or genetic determinateness. The activity of these factors is reflected in biomass production, flower drug production, content and composition of essential oil and some other ...

To further delineate the conceptual and operational properties of attitude structure, the relationship between affect and behavioral Intentions was tested by Campbell and Fiske's (1959) imiltitrait-multi■ethod matrix procedure. Involved were measures of affect, behavioral intentions, and a multiplicative function of measures of behavioral intentions and the affect toward the behaviors. The resu...

The main objective of this study was to determine the effects of vermicompost and amino acids on the qualitative and quantitative yield of chamomile. The experiment was conducted during the growing season of 2010 at the Alborz Medical Research Center. The Treatment groups consisted of vermicompost (0, 5, 10, 15 and 20 tons/ha) and the sprays of amino acids (budding stag, flowering stage, and bu...
