variability in morphological traits, phenolic content, and antioxidant activity of 15 populations of iranian ferula species collected from natural habitats in different regions of iran were investigated. total phenolic content (tpc) of fruit extracts varied from 12.77 to 120.72 mg tannic acid per 1g dry weight. total flavonoid of fruits extract varied from 5.45 mg quercetin per 1 g dry weight i...

a study was conducted at the research station of department of horticultural science (tehran university, karaj) to evaluate the effects of water stress on yield, growth and some physiological parameters in iranian melon. the experiment was set out in a split plot design with three replicates. treatments consisted of factorial arrangement of three irrigation levels (starting irrigation at -50, -...

physical properties of fruits and vegetables are the subject of many researches because of its importance in designing of agricultural machinery. banana fruit is one of important fruit. in this study some physical properties of banana fruit (cavendish variety) were determined. properties which were measured included weight of whole fruit peel and pulp weight, dimensions, surface area and projec...

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...

this research was conducted to study some vegetative and reproductive traits as well as qualitative andquantitative characteristics and their correlation in 80 almond genotypes. qualitative traits were studiedaccording to gulcan descriptor. quantitative traits were analyzed as completely randomized design(crd), with 12 replications. the results showed that genotypes had significant difference i...

Key mechanisms controlling fruit weight and shape at the levels of meristem, ovary or very young fruit have already been identified using natural tomato diversity. We reasoned that new developmental modules prominent at later stages of fruit growth could be discovered by using new genetic and phenotypic diversity generated by saturated mutagenesis. Twelve fruit weight and tissue morphology muta...

Resveratrol is a stilbene phytoalexin well-known for its presence in grape, wine, and peanut. As a result of its antioxidant and chemopreventative properties, it has gained much attention as a functional food ingredient. A gas chromatography-mass spectrometry method for the detection of resveratrol, its 3-glucopyranoside piceid, and the cis isomers of both compounds has been developed and used ...

This study describes morphological diversity and relationship of 14 cultivars and 133 wild fig accessions from central Zagros Mountains located in the west of Iran, based on 58 morphological characters. Among all characters, secondary drooping branches, number of bark tubers, shape of central lobe, length of central lobe/length of lamina, little lateral lobes, shape of leaf without lobed, fruit...

The impact of phenylphthalamic acid (PPA) rates including 0 (PPA0), 1000 (PPA1000), 2000 (PPA2000) or 3000 (PPA3000) mg L-1 and perfect fertilizer rates including 0 (PF0), 100 (PF100), 200 (PF200) and 300 (PF300) mg L-1 was studied on vegetative and reproductive growth of ornamental pep...

oxalate soluble pectin (osp) is related to fruit firmness with respect to the chelation of calcium ions with carboxyl groups of adjacent polyuronide chains. this study was carried out to explore the effect of time of fruit harvest, foliar spray with cacl2 during growing season on osp, polygalacturonase activity (pga), fruit firmness and the effects on fruit shelf life, quality and internal ...
