the following study was conducted at the research station of horticultural sciences (university of tehran, karaj) to investigate the effect of different irrigation levels and fruit site on the stalk upon the traits of: sink-source relationship, yield, and fruit quality in two iranian melon cultivars. the statistical design was a split split-plot of  three replications. treatments consisted of a...

The effectiveness of asexual and sexual reproduction of rare, clonal species Dianthus superbus L. were conducted in the years 2008-2010 in Kostrze (Southern Kraków). The observations were carried out in Molinietum caeruleae patches dominated by small species creating delicate, erect or procumbent stems (MC), prevailed by tall grasses (GR), and overgrown by willows (SA). The number of above-grou...

in order to prevent the shrinkage of olive fruit and maintain its fresh being, and  also to increase the oil content and dry matter, the effect of kaolin at three levels of application (0, 2.5% and 5%) on four varieties of olive (mission, conservolea, keillet, blady) was evaluated within a period of four months, in ahwaz, the tests being repated in 3 replicates. results revealed significant eff...

BACKGROUND Golden Rice (GR) has been genetically engineered to be rich in β-carotene for use as a source of vitamin A. OBJECTIVE The objective was to compare the vitamin A value of β-carotene in GR and in spinach with that of pure β-carotene in oil when consumed by children. DESIGN Children (n = 68; age 6-8 y) were randomly assigned to consume GR or spinach (both grown in a nutrient solutio...

Methylprednisolone (MP), a glucocorticoid, is the only effective therapeutic agent used in the clinical treatment of acute spinal cord injury (SCI). MP given within 8 hr after SCI significantly improves neurological function. Although the glucocorticoid receptor (GR) is suggested to mediate MP actions, limited knowledge is available on its expression and possible function after SCI. Presently, ...

Glucocorticoid receptor α (GR) binds to the promoter regions of target genes as a homodimer and activates its transcriptional process. Though the homodimerization is thought to be the initial and essential process, the dissociation constant for homodimerization of GR remains controversial. To quantify homodimerization of (enhanced green fluorescence protein) EGFP-(glucocorticoid receptor) GR, t...

We have studied a genomic library of introgression lines from the Solanum pimpinellifolium accession TO-937 into the genetic background of the "Moneymaker" cultivar in order to evaluate the accession's breeding potential. Overall, no deleterious phenotypes were observed, and the plants and fruits were phenotypically very similar to those of "Moneymaker," which confirms the feasibility of transl...

Relationships between respiration rate and adenylate and carbohydrate pools of the soybean (Glycine max L. Merrill) fruit during rapid seed growth were evaluated. Plants at mid pod-fill were subjected to different concentrations of CO(2) to alter the amount of photosynthate produced and, thus, available to the fruit. Respiration rate of the intact fruits was measured, along with glucose, sucros...

Physical and chemical parameters of fresh berries from three southern highbush (‘O’Neal’, ‘Sharpblue’ and ‘Misty’) blueberry cultivars grown in Huelva (Southwestern Spain) under two production systems were measured and evaluated. ANOVA applied to data yielded significant differences between production systems for mean fruit size and mean fruit fresh weight (P<0.05), although main effects on phy...

A moderate water deficit stress (S1) applied 10 days after anthesis was found to induce acclimation to a subsequent more severe drought stress (S2) in Solanum lycopersicum L.. When plants were pretreated with S1, and then subjected to S2, fruit water status remained similar to controls. In contrast, S2 induced a decrease in both parameters of water status and diameter of fruits from non-acclima...
