Impacts of different planting times on fruit quality and some bioactive contents of different strawberry cultivars

Abstract

Strawberry fruit quality traits can be affected by genotype-environment interactions, which determine the consumer acceptance of fruits. This factorial experiment was based on completely randomised blocks (RCBD) with two planting dates (5 and 20 April) and cultivars (‘Albion’, ‘San Andreas’ and ‘Portola’) of strawberry with three replications, and some of pomological and qualitative factors of berry were investigated at harvest. The results showed no significant difference on fruit width, length, weight and firmness, while the plant yield and stem diameter (SD) were affected by different cultivars and planting dates. The minimum SD (19.80) was recorded in cv. ‘Portola’ in the planting date of 20 April. Although the lowest fruit yield was achieved in cv. ‘Portola’ at both planting dates, it had the highest titratable acidity (TA) (0.83%) at the first planting date (5 April). The amount of soluble solid concentration (SSC), electrolyte conductivity (EC), pH, TA and chlorophyll were not affected by cultivar and planting dates. The effect of planting dates and cultivar had no significant effect on berry colour. The highest total phenolic (275.44 mg GAE · 100 mL-1 FW) was recorded in cv. ‘San Andreas’ on the planting date of 20 April, while the lowest value (251.22 mg GAE · 100 mL-1 FW) was recorded in cv. ‘Portola’ on the planting date of 5 April. In general, it is suggested that the least fruit yield in strawberry cv. ‘Portola’ can be correlated with the least SD of the cultivar.

Physico-Chemical Analysis of the Fruits and Consumer Preferences of New Apple (Malus × domestica Borkh) Hybrids Bred in Poland

“…The content of the mentioned components is largely a genetic trait, depending on the species and cultivar [50]. In addition to genetic factors [61], bioactive compound content is influenced by a number of external factors, such as fruit maturity, exposure of fruit to sunlight, length, and type of storage or cultivation location [62][63][64]. The cultivars evaluated in this experiment also differed in their content of bioactive compounds.…”

Effects of Inoculation with Plant Growth-Promoting Rhizobacteria on Chemical Composition of the Substrate and Nutrient Content in Strawberry Plants Growing in Different Water Conditions

“…It is highly regarded for the health, quality, and taste benefits of fruits [6,7]. Many authors have shown that both the leaves and fruits of strawberries possess a rich chemical profile, including readily absorbable sugars, dietary fibers, vitamins (especially vitamin C), and a range of bioactive compounds with antioxidant properties [8][9][10][11]. A prospective option for improving plant growth and drought tolerance is the application of plant growth-promoting rhizobacteria (PGPR) as inocules.…”

Health-Promoting Properties of Anthocyanins from Cornelian Cherry (Cornus mas L.) Fruits

“…Due to their common occurrence in plants, anthocyanins are present in the human diet. Quantitative and qualitative differences in the anthocyanin composition of fruit imply that these characteristics depend on plant species [ 12 ], cultivar [ 13 ], growth conditions [ 14 ], ripeness, storage [ 15 ], and processing methods [ 16 ]. The main sources of anthocyanins in a temperate climate zone are grapes, chokeberry, blackcurrant, and elderberry.…”
