in order to study the effects of ga3and cacl2 treatments in resolve the problems of sweet pepper culture in ilam region (including small size fruits with sunscald and blossom end rot disorders), this study was carried out in ilam university in 2012. for that, ga3 (50 mg/l) and cacl2 (0.5%) treatments were sprayed at two (fruit set and 15 days thereafter) and three (fruit set, 10 and 20 days the...

abstract almond is an important nut tree which is cultivated in many mediterranean countries. this study was carried out to study some vegetative and reproductive traits as well as qualitative and quantitative characteristics and their correlation in some self-compatible and self-incompatible genotypes obtained from crossing between touno (male parent) and shahrood 12 (female parent). quantitat...

background and objectives: apple is the most important horticultural crops that is allocated large share of world trade in agricultural products. principles of sustainable fruit production systems are based on optimal use of natural resources (light, water, soil fertility) where the input (labour, energy, fuel, other material) and output (yield) are well balanced and the resources remain renewa...

Identification of Superior Parents and Hybrids Tomato (Solanum Lycopersicum L.) Genotypes for Some Quantitative Qualitative Traits Fruit under Drought

There is a large genetic diversity for fruit size and yield in watermelon [Citrullus lanatus (Thunb.) Matsum. & Nakai var. lanatus]. Current cultivars have high fruit quality but may not be the highest yielders. This study was designed to estimate variance components and heritability of fruit yield (Mg·ha), fruit count (th·ha), and fruit size (kg/fruit) in a cross involving high-yielding ‘Mount...

Peach (Prunus persica L. Batsch) was chosen as a model to shed light on the physiological role of jasmonates (JAs) during fruit ripening. To this aim, the effects of methyl jasmonate (MJ, 0.40 mM) and propyl dihydrojasmonate (PDJ, 0.22 mM), applied in planta at different fruit developmental stages, on the time-course of ethylene production and fruit quality traits were evaluated. MJ-induced cha...

in order to evaluate the effect of water stress on fruit quality and quantity of some iranian melons, the experiment was set out in a split plot design with three replicates in research filed of university of zanjan in 2014. treatments consisted arrangement of three irrigation levels (starting irrigation at 100, 66 and 33 etc) and 11 genotypes of iranian melons (ʼkhatouniʻ, ʼkaliʻ, ʼorshangʻ, ʼ...

cantaloupe is a common crop and relatively important in iran which show high genetic diversity. forty nine genotypes including seven iranian endemic cantaloupes rishbaba, shahabadi, samsori, dastjerdi, magasi, tiltorogh and savei and their direct and reciprocal crosses were evaluated during two years using triple lattice design. results indicated the positive and significant correlations betwee...

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 '...

Domestication of crop plants selects for numerous traits that often distinguish them dramatically from their wild progenitors. In some cases, these modifications lead to increased herbivory, by enhancing their attractiveness to herbivorous insects or reducing the efficiency of natural enemies, or both. This study investigated the effects of fruit enlargement on the olive (Olea europaea L.), the...
