An increasing world population and the competitive nature of the stone fruit market, particularly nectarines [(Prunus persica var. nectarine)], demand the selection of fruit with high quality attributes, flavor, and a wide range of maturity. Information on this subject is limited at the present time. In search of superior nectarines, a trial was conducted to study growing degree days (GDD), ful...

Peach is a highly corrosive fruit with a short shelf life (less than 7 days at room temperature)susceptible to diseases, pathogens and physical damage. The storage or marketable life ofhorticultural crops can be extended by various treatments applied to them after and/or beforeharvesting. Fruits are usually treated with a range of materials [(e.g. salicylic acid (SA)] to...

Seaweeds are rich sources of bioactive natural products, which have been considered as potential biotic agents. Ulva flexuosa Wulfen is a species of seaweed which is endemic to the Persian Gulf. In this study, the effect of different concentrations of U. flexuosa extract on  the  antioxidant activity of Washington Navel orange (Citrus sinensis L. cv. Washington Navel)...

some physical properties and chemical compositions of two cultivars (semsouri and shahabadi) of cantaloupe studied during four different stages of maturity from fruit set to completely ripe. the physical properties investigated were the geometric mean diameter (gmd), specific gravity (sg), mean firmness (mf), rind, seed (%) and flesh (%). the chemical compositions were brix, titrable acidity (t...

abstract to study the effects of different levels of n, mn and zn on yield and quality of pomegranate fruit a factorial experiment based on complete randomized block design with 18 treatments and three replications was conducted in behshahr city, mazandaran province, in 2009.investigated treatments were include: nitrogen, manganese, zinc. fertilizer source for nitrogen was urea and three rates ...

flowering and fruit production of ‘nagami’ kumquat is somewhat different from other citrus species because usually have three flowering peak in a year which can lead to producing fruits with different quality on a tree. considering the proper effect of paclobutrazol on raising citrus flowering, a pot experiment with three levels of paclobutrazol (zero, 0.1 and 0.5 g ai per tree) and six replica...

In peach fruits, phenolic compounds serve as a major source of potential antioxidants which are known to play a significant role in fruit quality and in human wellbeing. This study was conducted in a F1 population derived from the cross ‘Venus’ x ‘Big Top’ nectarines in order to investigate the variability in the fruit antioxidant content and to study the genetic control and location of QTLs in...

Auxin is one of the most prominent phytohormones regulating many aspects of fleshy fruit development including fruit set, fruit size through the control of cell division and cell expansion, and fruit ripening. To shed light on the role of auxin fruit ripening, we have previously shown that Sl-ARF4 is a major player in mediating the auxin control of sugar metabolism in tomato fruit (cv MicroTom)...

A decline in pollination function has been linked to agriculture expansion and intensification. In northwest Argentina, pollinator visits to grapefruit, a self-compatible but pollinator-dependent crop, decline by approximately 50% at 1km from forest edges. We evaluated whether this decrease in visitation also reduces the pollination service in this crop. We analysed the quantity and quality of ...
