Genetic variation of 36 Sechium edule accessions collected across 12 states in India was assessed using morphological traits and DAMD markers. Eighteen fruit morphological traits (both qualitative and quantitative) were evaluated to confirm the variations in the present collection. Quantitative traits showed major variations with respect to fruit weight (7.85-498.33 g/fruit), fruit length (5.8-...

GRAS family transcription factors are involved in multiple biological processes in plants. Here, we report that GRAS2 plays a vital role in regulating fruit weight in tomato (Solanum lycopersicum). We establish that the expression of GRAS2 was elevated in ovaries and maintained at a constant level in fertilized ovules. Reduction of GRAS2 expression in transgenic plants reduced fruit weight thro...

the effect of ca, zn and b spray application on preharvest fruit drop, sugars, calcium, zinc, and boron concentrations and as well on some physicochemical fruit properties of five commercial asian pear cultivars (‘ks’7, ‘ks’8, ‘ks’11, ‘ks’12 and ‘ks’14) was investigated under tehran province,s environmental conditions. trees were sprayed one month past fruit set until harvest within two week in...

We applied a semi-mechanistic model of fresh matter accumulation to peach fruit during the stage of rapid mesocarp development. The model, which is based on simple hypotheses of fluid flows into and out of the fruit, assumes that solution flow into the fruit increases with fruit weight and transpiration per unit weight, and decreases with the maximum daily shrinkage of the trunk, which was used...

In spite of the numerous-available clones and cultivars of date palm, few of them produce non-astringent dates at the khalal stage. The astringent fruit must convert to the rutab stage to be edible as fresh dates which means the conversion of soluble tannins to the insoluble form. Applications of the ethylenereleasing compound, namely, Ethrel, even at very high concentrations failed to induce r...

Using an F1 population from a cross between Japanese pear (Pyrus pyrifolia Nakai) cultivars 'Akiakari' and 'Taihaku', we performed quantitative trait locus (QTL) analysis of seven fruit traits (harvest time, fruit skin color, flesh firmness, fruit weight, acid content, total soluble solids content, and preharvest fruit drop). The constructed simple sequence repeat-based genetic linkage map of '...

cross pollination in some of apples cultivar exists; also iran is near the origin of apple trees so, large genetic diversity can be seen between iranian cultivar. also very famous apple cultivar is known in iran for special flavor and taste. the name of this cultivar is golab. this research was studied in the years 2010 and 2011 in khorasan razavi province on golab apple ecotypes to evaluate ch...

Bagging of female inflorescence following pollination has recently received growers attention. Although this process occurs early in the season but affects fruit quality, yield, and marketability. Date palm growers have used to use grocery paper bags for this bagging process. Since inflorescence bagging causes what is called the greenhouse effect, it was very important to investigate the effect...
