a number of grapevine cultivars have female flowers and for better fruit set, they need pollinizer. single planting of these cultivars leads to severe decrease in fruit set. this research was carried out to investigate the effect of cross pollination with four grape cultivars (askari, rish baba, bidane sefid and tabarze sefid) on fruit set, bunch weight, berry per cluster, average weight of 20 ...

apricot (prunus armeniaca), palys an important role in fruit production industry in iran. irregular set of fruit, caused by either sterility of flower organs or incompatibility has been the main problem in apricot production over the years. in this study, it has been attempted to determine these phenomena for four apricot cvs. namely ‘shahroodi’, ‘nasiri’, ‘jahangiri’ and ‘noori’ through the me...

 Rosemary (Rosmarinus officinalis L.) is an important medicinal plant that contained a wide range of secondary metabolites such as rosmarinic acid. In this study, essential oil content and composition and rosmarinc acid were determined at three phenological stages (before flowering, full flowering and fruit set stages). Hydro distillation method was used for essential oil extraction and GC and ...

apricot (prunus armeniaca l.) is a species particularly prone to erratic fruit set, and its flower bud drop has been repeatedly reported in different cultivars and growing conditions. a number of potential causes have been explored, but a clear main cause remains elusive. in this study, fruit set was determined for 11 apricot cultivars (‘precoce de tyrinthe’, ‘feriana’, ‘beliana’, ‘priana’, ‘be...

BACKGROUND AND AIMS Fruit set in indeterminate plant species largely depends on the balance between source and sink strength. Plants of these species show fluctuations in fruit set during the growing season. It was tested whether differences in fruit sink strength among the cultivars explained the differences in fruit-set patterns. METHODS Capsicum was chosen as a model plant. Six cultivars w...

in order to determinate the self–incompatibility and the most suitable pollinizer for esfahan commercial quince cultivar, the effects of four different pollinizer treatments ((km1, pk2, kvd2, nb4), as self pollination and open pollination) on fruit set and quantitative and qualitative characteristics of commercial quince fruits of isfahan were studied in a randomized complete block design with ...

field experiment was conducted to determine the economic threshold for spraying of flubendiamide against the brinjal shoot and fruit borer. flubendiamide was applied based on 10 thresholds including 2% shoot infestation, 5% shoot infestation, first fruit set + 2% fruit infestation, first fruit set + 5% fruit infestation, 2% fruit infestation, 5% fruit infestation, 2% shoot + 2% fruit infestatio...
