Title: SUSTAINABILITY OF COLD-CLIMATE STRAWBERRY PRODUCTION SYSTEMS Matthew Dexter Stevens, Master of Science, 2005 Directed By: Associate Professor, John D. Lea-Cox, Department of Natural Resource Sciences and Landscape Architecture Three cold-climate strawberry (Fragaria xananassa Duch.) production systems, conventional matted row (CMR), advanced matted row (AMR), and coldclimate plasticultur...

abstract an investigation was undertaken to ascertain the influence of hydro-alcoholic solutions on plant growth as well as quality attributes of strawberry fruits. the mother plants of strawberry (fragaria ananasa cv. gaviota) were subjected to various aqueous solutions of ethanol (15, 30%), methanol (15, 30%) and the mixture of ethanol + methanol (15 or 30%) plus the control (water only) as f...

Eight plant densities (8.8, 9.5, 10.4, 11.4, 17.6, 19.1, 20.8, and 22.9 plants m ) in 2001–2002 and 12 plant densities (8.8, 9.5, 10.4, 11.4, 12.7, 14.3, 17.6, 19.1, 20.8, 22.9, 25.4, and 28.6 plants m ) in 2002–2003 were evaluated on growth and fruit yield of ‘Sweet Charlie’ strawberry (Fragaria ananassa Duch.) grown in a passively ventilated greenhouse. Plant densities were derived by varying...

Pollination contributes to an estimated one third of global food production, through both the improvement of the yield and the quality of crops. Volatile compounds emitted by crop flowers mediate plant-pollinator interactions, but differences between crop varieties are still little explored. We investigated whether the visitation of crop flowers is determined by variety-specific flower volatile...

Xanthomonas fragariae is a worldwide-spread plant bacterial disease causing angular leaf spots, thus reducing the yield of production for strawberry fruits. Three isolates with various geographic and time origins were sequenced with long-read technology (PacBio) to generate finished genome sequences of virulent strains and observe the variability in their contents.

Peat based growing media are not ecologically sustainable and often fail to support biological control. Miscanthus straw was (1) tested to partially replace peat; and (2) pre-colonized with a Trichoderma strain to increase the biological control capacity of the growing media. In two strawberry pot trials (denoted as experiment I & II), extruded and non-extruded miscanthus straw, with or without...

five levels of salicylic acid (sa), (0, 2, 4, 6 & 8 mm) were sprayed on strawberry cv. comarosa fruit bearing plants in a hydroponic culture. growth, yield & fruit quality attributes were assessed. vegetative characteristics (crown number, root & shoot weight), reproductive traits (yield, fruit number as well as shape), fruit quality, macro elements (ca, mg, k & p), dry weight & ash were evalua...

Strawberry ( Fragaria × ananassa ) is grown during the winter months in subtropical southern Florida and must thrive higher than average temperatures limestone soils. This first strawberry cultivar trial to include ‘Florida Beauty’, Brilliance’, ‘Strawberry Festival’, Radiance’, ‘Sensation FL127’, ‘Winterstar’. Overall, Festival’ FL127’ were top yielding cultivars, with highest total yields of ...
