low seed yield is a limiting factor for cross breeding and hybrid seed production in cyclamen. this study was performed to investigate pollen germination and its relation to cross-pollination success and fruit set in this plant. in order to achieve a high level of pollen germination, the effect of different concentrations of chemical compounds were examined on in vitro pollen germination of cyc...

Objective: In several nations, royal jelly is used in apitherapy, healthful foods, and cosmetics. The production quality of collected from honeybee colonies are being worked on by researchers beekeepers. This study investigated the effect honey pollen substitute feeding efficiency jelly. addition, analyses were conducted to determine differences between fed unfed groups terms 10-hydroxy-2-decon...

The concept system around ‘quantity’ and ‘quantity value’ is fundamental for measurement science, but some very basic issues are still open on such concepts and their relations. This paper proposes a duality between quantities and quantity values, a proposal that simplifies their characterization and makes it consistent.

In this study, the amount of flavonoid aggregates in pollen common almond (Amygdalus communis L.) plant, which is Nakhchivan MR, was analyzed. The study flavonoids can provide useful information for assessing nutritional and healing quality bee products. an extract prepared on 60% ethyl alcohol from plant. For determination flavonoids, a solution 2% aluminum chloride standard rutin were used. B...

 In 2007 and 2008, the influence of pollen source on the shell and kernel traits of resulting seeds and on fruit set was examined to evaluate the potential for Xenia or Metaxenia in Persian walnut. Pistillate flowers of ‘Jamal’, ‘Chandler’, ‘Hartley’ and ‘Pedro’ were crossed with the pollen of ‘Serr’, ‘Z60’ and ‘Damavand’. The pistillate flowers on each female parent were covered about one week...
