Development, imaginal survivorship, adult longevity and fecundity of the predatory phytoseiid mite Euseius (Amblyseius) finlandicus Oudemans reared on seven different plant pollens were determined in the laboratory. The rationale behind these experiments was to assess the nutritional value and the possible effect on development and population dynamics of the mite. Mites were kept individually o...

Pollination of many flowers leads to an increase in ethylene synthesis and flower senescence. We have investigated the regulation of pollination-induced ethylene synthesis in tomato (Lycopersicon esculentum) using flowers of the dialytic (dl) mutant, in which pollination can be manipulated experimentally, with the aim of developing a model system to study tomato flower senescence. Ethylene synt...

in vitro pollen germination and also pollen tube growth dynamics in different pollination treatments under controlled temperature, humidity and photoperiodicity were studied regarding four cultivars (‘shastomi - e - do’, ‘ebrahim - e - kalajah’, ‘sefid - e - rezaeeieh’ and ‘razi’) under self and under cross-pollination along with three superior genotypes (‘269’, ‘416’ and ‘464’) of apricot. fol...

orchard workers in north china are highly exposed to orchard pollens, especially peach and other rosaceae family pollens during pollination season. the aim of this study was to investigate whether occupational allergy to peach tree pollen as a member of rosaceae family is ige-mediated and to evaluate the cross-reactivity among rosaceae family pollens. allergen skin test and conjunctival challen...

allergic rhinitis is an extremely common disease worldwide. aeroallergens are very often involved in allergic rhinitis and their prevalence may vary in differ¬ent regions. the causative allergens of allergic rhinitis in our area are unknown. the purpose of this study was to determine the prevalence of skin reactivity to different aeroallergens in patients with allergic rhinitis in the city of s...
