The aim was to estimate the impacts of invasive Impatiens parviflora on forests' herbal layer communities. A replicated Before-After-Control-Impact field experiment and comparisons with adjacent uninvaded plots were used. The alien's impact on species richness was tested using hierarchical generalized mixed effect models with Poisson error structure. Impact on species composition was tested usi...

Fruit set and quality in strawberry cv. Selva were influenced by salinity (NaCl) and supplementary calcium and potassium (CaSO , CaCl , K SO ) treatments applied to the root medium of plants growing in 4 2 2 4 soilless culture under heated greenhouse conditions. Yield components such as primary fruit weight and fresh fruit weight (at harvest time) and fruit number were higher in control and the...

BACKGROUND AND AIMS Many plants reproduce both clonally and sexually, and the balance between the two modes of reproduction will vary among populations. Clonal reproduction was characterized in three populations of the wild strawberry, Fragaria virginiana, to determine the extent that reproductive mode varied locally between sites. The study sites were fragmented woodlands in Cook County, Illin...

Strawberries represent an important source of bioactive compounds due to their vitamin C and phenolic compound levels, which present high antioxidant effects, beneficial for the maintenance of consumer's health. Argentina is the second largest strawberry producer in The Common Market of the Southern Cone (MERCOSUR), covering the main export destinations of Argentinian strawberries, i.e., Canada...

This study investigated the occurrence of resveratrol in Fragaria x ananassa Duchesne and the effect of preharvest conditions on resveratrol content. Both cis- and trans-resveratrol were detected in strawberry achenes (seeds) and pulp (receptacle tissue). Resveratrol was found to be higher in achenes than in fruit pulp. The levels of resveratrol were affected by genotype variations, fruit matur...

Anthocyanins are responsible for fruit coloration and beneficial to human health. The fruits of cultivated strawberry ( Fragaria ×ananassa ) varieties colorful, a trait that attracts consumers. wild species, close relatives the strawberry, vary in color. In this review, we describe content composition anthocyanins varieties. We also explore biosynthetic pathway anthocyanins, including their tra...

Title of Document: ELEVATED TEMPERATURE EFFECTS ON CAROTENOID BIOSYNTHESIS IN THE DIPLOID STRAWBERRY, FRAGARIA VESCA Melantha E. Jackson, Doctor of Philosophy, 2015 Directed By: Professor Herman Sintim Department of Chemistry and Biochemistry Carotenoids, a subfamily of the isoprenoids, are one of the most diverse classes of secondary metabolites distributed throughout nature. They are lipophil...

Fragaria vesca (2n = 2x = 14), the woodland strawberry, is a perennial herbaceous plant with a small sequenced genome (240 Mb). It is commonly used as a genetic model plant for the Fragaria genus and the Rosaceae family. Fruit skin color is one of the most important traits for both the commercial and esthetic value of strawberry. Anthocyanins are the most prominent pigments in strawberry that b...
