a study of the combining ability and gene effects, that can obtained through diallel cross analysis provides considerable information to breeders for a design of breeding programs. inheritance and genetic control of yield and its components were studied in a full diallel cross for seven iranian cantaloupe cultivars namely: rish-baba, shah-abadi, samsouri, dastjerdi, magasi-neyshabour, till-toro...

to study the effects of planting date and planting density on quantitative traits of medicinal plant, schneider squash (cucurbita pepo l.), an experiment was conducted at research field of ferdowsi university of mashhad, in year 2012. a split plot arrangement based on randomized complete block design with three replications was used. treatments consisted of three planting date levels (1 may, 11...

In this experiment (in the absences of disease pressure) the application of Mycostop had no effect on yield or quality of fruit harvested. Nutrient and irrigation application based on the amount of solar radiation received by the crop reduced the amount of nutrient used without reducing yield or quality. Fruit quality was higher with lower amounts of irrigation but yield increased with increase...

BACKGROUND AND AIMS There is good evidence for deciduous trees that competition for carbohydrates from shoot growth accentuates early fruit abscission and reduces yield but the effect for evergreen trees is not well defined. Here, whole-tree tip-pruning at anthesis is used to examine the effect of post-pruning shoot development on fruit abscission in the evergreen subtropical tree macadamia (Ma...

Orchard intensification is motivated by the desire to produce fruit early in the life of the orchard to rapidly recover establishment costs. Intensification is possible using dwarfing rootstocks that control tree size, induce early cropping and produce large quantities of fruit compared to the amount of wood produced. Therefore, this study attempts to compare some yield and fruit properties of ...

Regulated deficit irrigation (RDI) is commonly used during different phenological stages of fruit growth and development in almond trees to reduce the amount of irrigation water applied without or with only very small reductions in yield. Therefore, to study the effects of deficit and cutoff irrigation during different phenological stages of fruit growth and development in almond cv. “Mamaei” p...

using mulch to decrease and optimize water use is known as a practical method. for this purpose, a split-factorial experiment based on complete block design with three replications on two melon cultivars was conducted in spring season of 2010 in torbat-e-jam. interval irrigation treatments in three levels (6, 8 and 10 days) were considered as main plot and mulch (straw plus paddy rice, plastic ...

Chemical control of the citrus nematode, Tylenchulus semipenetrans Cobb, has consistently increased yield of grapefruit on sour orange rootstock in Texas. In this study, data from chemical control tests conducted from 1973 to 1980 were analyzed to determine the relationship between nematode counts and grapefruit yield and fruit size. The correlation between yield and nematode counts was negativ...

tomato production, growing nearly 40 percent of world supply. The majority of fruit is processed into concentrated paste, but an increasing percentage is being used for products utilizing peeled fruit, either whole or diced. Important fruit quality attributes for paste production are soluble solids content (SS) and color of the blended product. Uniformity of color is more important for peeled f...
