damage caused by freezing can be the result of differences in cellular processes, including changes in membrane properties, interactions between macromolecular and enzymatic reactions. in this experiment, total soluble solids (tss) and relative water content of the reproductive buds of cultivars “j. h. hale”, “elberta,” “redhaven, ” “sorkh sefid mashhad” and “amsden” peaches, along with nectari...

Peaches/nectarines (Prunus persica L.) are widely cultivated worldwide. As with other species, the sugar content is most important trait for fruit quality, especially precocious cultivars. Most fruits need to improve their in order be more profitable under fierce market competition. 5-Aminolevulinic acid (ALA), a naturally occurring δ-amino acid, has been shown leaf photosynthesis and content. ...

The development of sustainable products and practices must be supported by methodologies capable evaluating their environmental performance in an objective systematic manner. most popular tool for carbon footprint (CF) assessment is arguably process-based life cycle (pLCA). However, interest tools such as environmentally extended input-output analysis (EEIOA) growing rapidly due to the convenie...

In peach fruits, phenolic compounds serve as a major source of potential antioxidants which are known to play a significant role in fruit quality and in human wellbeing. This study was conducted in a F1 population derived from the cross ‘Venus’ x ‘Big Top’ nectarines in order to investigate the variability in the fruit antioxidant content and to study the genetic control and location of QTLs in...

GOVERNMENT mandated commodity market­ ing programs continue to be both popular and controversial. These programs, which are re­ quested, approved, and funded by California produc­ ers, have the stated objectives of contributing to or­ derly marketing and/or improving producers’ returns. Their popularity is reflected by their long-standing use and the number of California commodity groups which ...

Identification of DNA markers associated with mealiness trait is an important tool to agricultural industry. Many peach breeding initiatives have as aim to improve early selection of varieties with better postharvest performance. We present a family-based approach to identify and develop an association panel to evaluate potential varieties susceptible to mealiness induced by chilling. We used w...

A breeding program searching for new peach and nectarine varieties adapted to the Ebro Valley growing conditions is being developed at the Aula Dei Experimental Station (CSIC). This program evaluates 15 populations obtained by controlled crosses. Different agronomic parameters such as blooming date, yield, and ripening date were determined in these populations. Quality traits such as fruit type...
