an experiment was conducted to evaluate the effects of some technological processes on the residual levels of imidacloprid in strawberry fruits and products. according to their half-life (t1/2) values, strawberry fruits can be safely harvested for human consumption 7.4 days after spraying. the removal ratio of imidacloprid residue in strawberries was in the range of 9.9–30.55% by washing with t...

The KNOTTED-LIKE HOMEODOMAIN (KNOX) genes play a central role in maintenance of the shoot apical meristem. They also contribute to the morphology of simple and compound leaves. In this report we characterize the FaKNOX1 gene from strawberry (Fragaria spp.) and demonstrate its function in trasgenic plants. The FaKNOX1 cDNA was isolated from a cultivated strawberry (F.×ananassa) flower EST librar...

Seasonal abundance of the strawberry aphid complex under different agronomic practices in the outskirts of La Plata, Argentina was studied on strawberry, Fragaria x ananassa Duchesne (Rosales: Rosaceae). Aphid densities were low in strawberry fields in which insecticides and fungicides were used. In addition to Aphis gossypii, Aphis fabae, Mysus persicae and Macrosiphum euphorbiae, the aphid, C...

Fresh fruit of three strawberry cultivars Fragaria ananassa × Duch. (cvs. ‘Clery’, ‘Honeoye’ and ‘NF 421’ (Asia)) were investigated and used to produce jams, which were analyzed before and aft er dark storage at 20 °C for six months. Th e aim of this investigation was to characterize all the samples in relation to the total phenolics, fl avonoids, nonfl avonoids, total anthocyanins and antioxid...

Allelopathic effects of juglone and walnut leaf extracts from Persian walnut (Juglans regia L.) on yield, growth, chemical and plant nutrient element composition of the day-neutral strawberry (Fragaria × ananassa L.) cultivar Fern were investigated as part of an effort to identify tolerant species to plant adjacent to walnut. Strawberry plants were treated with juglone (5-hydroxy-1.4 naphthoqui...

Strawberry and wild strawberry are among the most popular horticultural crops. Due to development of soilless cultivation systems, whole-year production these economically important fruit crops is achievable even in countries with temperate climate. However, responses (Fragaria × ananassa Duch.) vesca L.) microclimate conditions greenhouse gutter autumn–winter season Poland have not been yet de...

Abstract Cultivated strawberry (Fragaria × ananassa) is one of our youngest domesticates, originating in early eighteenth-century Europe from spontaneous hybrids between wild allo-octoploid species chiloensis and Fragaria virginiana). The improvement horticultural traits by 300 years breeding has enabled the global expansion production. Here, we describe genomic history domestication earliest t...
