High temperature is one of the most important environmental factors that affect the successful cultivation of apple (Malus × domestica Borkh). The expression of genes related with anthocyanin synthesis and sugar accumulation by high temperature treatment was investigated in the fruits of “Fuji” apple at different developmental stages in different temperature conditions through realtime PCR. In ...

This study aimed at understanding softening in Jonagold apple (Malus×domestica Borkh.) fruits, by investigating pectin modifications and the evolution of pectin-modifying enzymes during postharvest storage and ripening. Jonagold apples were harvested at commercial maturity and stored at different temperatures and controlled atmosphere conditions for 6 months, followed by exposure to ambient she...

Plant NADPH-dependent glyoxylate/succinic semialdehyde reductases 1 and 2 (GLYR1 and GLYR2) are considered to be involved in detoxifying harmful aldehydes, thereby preserving plant health during exposure to various abiotic stresses. Phylogenetic analysis revealed that the two GLYR isoforms appeared in the plant lineage prior to the divergence of the Chlorophyta and Streptophyta, which occurred ...

Seasonal changes in photosynthesis of apple trees (Malus domestica Borkh.) were monitored to examine the effect of source-sink interactions on photosynthesis and photorespiration. Elevated photosynthetic rates were observed during two periods of the growing season and correlated with the fruiting process. The first period of increased photosynthetic rates was during the bloom period, when spur ...

Enzymatic browning of apple fruits (Malus × domestica Borkh.) is the main factor responsible for quality deterioration in processed products such as juice, fresh-cut slices and chips.The fresh slices of apple were dipped in 1% ascorbic acid solution for one min and hot water with 50°C for two min. The results showed that both heat and ascorbic acid treatments could significantly reduce cut surf...

This study reports the presence and injuries caused by Tetranychus ludeni Zacher, 1913 (Acari: Tetranychidae) on apple tree seedlings (Malus domestica Borkh: Rosaceae) in nurseries southern Brazil. The ability of predatory mite Phytoseiulus macropilis (Banks, 1904) Phytoseiidae) to control T. infestations this environment was also evaluated. infestation observed during routine monitoring at Aca...

Fire blight, caused by epiphytotic gram-negative bacteria Erwinia amylovora, is the most destructive bacterial disease of apple (Malus spp.). Genetic mechanisms fire blight resistance have mainly been studied using traditional biparental quantitative trait loci (QTL) mapping approaches. Here, we use large-scale historic shoot and blossom data collected over multiple years genotyping-by-sequenci...

The 'Anna' apple is a variety of low requirements winter chill (250 to 300 chilling hours ≤7.2°C). This has essential health benefits and remarkable adaptive potential in tropical subtropical areas affected by climate change. Thus, this review presents the significance cultivation, phenological eco-physiological modifications, current state agronomic management when continuous crops are managed...
