grape vine is one of the important horticultural crops with unique standing as regards use and consumption. the fruit is utilized from immature to ripened state and as raisins. its leaves can be used when they are soft and fresh. therefore it is necessary to improve iranian grapevine quality as well as quantity. the main purpose of this study was the use of phenyl phetalamic acid (ppa) to incre...

Heterogeneity in fruit quality constitutes a major constraint in agri-food chains. In this paper the sources of the heterogeneity in pineapple in the field were studied in four experiments in commercial pineapple fields. The aims were to determine (a) whether differences in pineapple fruit quality among individual fruits are associated with differences in vigor of the individual plants within t...

abstract to investigate the effects of paclobutrazol (pbz) on vegetative and reproductive growth of strawberry cv. selva a factorial experiment in a completely randomized design with three replications was carried out in greenhouse of agriculture college, isfahan university of technology. pbz was applied in two methods, drench and foliar spray, at 0, 0.5, 1, 1.5 and 2 mg active ingredient per p...

this study was conducted to investigate the effects of irrigation frequency and substrates on some parameters of greenhouse tomato (cv. hamra) during 1381-1382 at research greenhouse of agriculture college, in ferdowsi university of mashhad. the experiment was based on split plots in the form of completely randomized design and in four replications. irrigation frequency in three levels of 12, 8...

Kernel weight is important for plant breeders to select high productive plants. The determination of relationships between kernel weight and some fruit-kernel characteristics may provide necessary information for plant breeders in selection programs. In the present study, the relationships between kernel weight (KW) and 7 fruit-kernel characteristics: Fruit Length, (FL,), Fruit Width (FW) Fruit...

most sweet cherry cultivars are as found as self-incompatible and therefore for commercial fruit production, compatible pollinizers are needed. controlled pollination and microscopic examination of pollen tube growth in the style are two classical methods for determination of compatible and incompatible pollen donor cultivars. this experiment was carried out to explore the compatibility of ‘zar...

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 ...

Gilaburu (Viburnum opulus L.) grown naturally in Anatolia. In this study, some physico-chemical (sugar, acid, protein, crude fat, crude fiber, ash etc.) characteristics and mineral composition of Gilaburu fruit have been investigated. The length, width, thickness, weight, total soluble solid, protein, crude ash, crude fiber and crude oil of fruit were found to be 1.12 cm, 1.58 cm, 1.87 cm, 0.87...
