Heat-tolerant and -sensitive Lycopersicon esculentum Mill. and L. pimpinellifolium (Jusl.) Mill. genotypes were grown in the greenhouse under optimum(27/23C, day/night) and high-temperature (35/23C) stress regimes. Heat tolerance levels in the genotypes were established by determining percent fruit set at high and optimum temperatures. Under optimum temperature, fruit set ranged from 41% to 84%...

Seventeen blackberry cultivars were evaluated for postharvest fruit-rot resistance in June and July, 2003. Fully mature, undamaged berries were harvested on two dates for each genotype at the University of Arkansas Fruit Substation, Clarksville. After transporting in chilled coolers to the Plant Pathology Department in Fayetteville, two replications of 10 berries of each genotype were placed in...

growth in plants is defined as irreversible increase in volume and size. these changes are varied depending on stage of growth and physiological activity of the fruit tree. this research was conducted to determine the duration period of fruit growth and development and to come up with a mathematical model representing the relationship between fruit diameter, volume, and fruit fresh and dry weig...

In the unconventional climacteric fig (Ficus carica) fruit, pollinated and parthenocarpic fruit of the same genotype exhibit different ripening characteristics. Integrative comparative analyses of tissue-specific transcript and of hormone levels during fruit repining from pollinated vs. parthenocarpic fig fruit were employed to unravel the similarities and differences in their regulatory proces...

Abstract Background Loquat cultivars cultivated in Southern Italy are very appreciated by consumers for their sensorial characteristics, such as persistent aroma and taste. Apposite maturity indexes peeling processing loquat fruit were investigated to increase diffusion of minimally processed loquat. The genotype’s effect on the shelf life quality harvested at commercial (80% yellow color) was ...

Ethylene has long been considered the key regulator of ripening in climacteric fruit. Recent evidence showed that auxin also plays an important role during fruit ripening, but the nature of the interaction between the two hormones has remained unclear. To understand the differences in ethylene- and auxin-related behaviours that might reveal how the two hormones interact, we compared two plum (P...

quince fruit has many benefits to human health and is an excellent source of pectin for jellies and jam industry. the objective of the present research was to study fruit physio-chemical attributes of some quince genotypes at harvest and their changes during cold storage. the fruit of 15 genotypes were harvested at optimum maturity and stored for 0, 30, 60, 90 and 120 days in cold storage and s...

Myeloperoxidase (MPO), an antimicrobial enzyme in the breast, generates reactive oxygen species (ROS) endogenously. An MPO G463A polymorphism exists in the promoter region, with the variant A allele conferring lower transcription activity than the common G allele. Because oxidative stress may play a role in breast carcinogenesis, we evaluated MPO genotypes in relation to breast cancer risk amon...

In this study, we investigated how increasing temperature affects tomato fruit physicochemical traits and looked for genetic variability to help maintain quality in the context of climate change. High (HT: +3 °C) was applied at four developmental stages, from anthesis 15, 30 or 45 days after until ripening three genotypes, a commercial cultivar (Money Maker, “MM”) two genotypes likely more tole...

Quantitative real-time RT-PCR (qRT-PCR) has become one of the most widely used methods for accurate quantification of gene expression. Since there are no universal reference genes for normalization, the optimal strategy to normalize raw qRT-PCR data is to perform an initial comparison of a set of independent reference genes to assess the most stable ones in each biological model. Normalization ...
