pollen storage could facilitate the date palm hand pollination through saving time and space. the main concern is maintaining pollen viability, which is greatly cultivar dependent and is influenced by storage condition. in this study, to address this issue, the effects of cultivar, storage temperature, and time on pollen germination were investigated. a factorial experiment was laid out in a co...

New approaches for treatment of infectious diseases in aquatic animals have important roles in aquaculture technology progress. In the present study, In vitro effects of different extracts of propolis, royal jelly and pollen obtained from beehives have been investigated on aquatic pathogenic bacterial isolates. The isolated bacteria identified on the basis of their biochemical properties and se...

This study was conducted to determine the best pollinizer for five selected pecan cultivars in southwest of Iran at Safiabad Agricultural Research Center in 2014-2015. The cultivars included: 'GraTex', '10J', 'Wichita 6J', 'GraKing', 'Choctaw' as pollinated cultivars (♀) and 'GraTex', 'Peruque', 'Comanche 4M', '10J', 'Wichita 6J', 'Mohawk', 'Mahan', 'Stuart 2J', '3J', 'Stuart 4J', 'GraKing', 'C...

allergic rhinitis (ar) is a very frequent disease which is not only characterized by nasal symptoms, but also with behavioural changes. this study evaluated the serum serotonin levels in patients with pollen-induced ar during and outside the pollen season. one-hundred-two  (56 females, 46 males, median age: 28.7 years) were included in this study: 56 with seasonal ar (sar) evaluated outside the...

background: platanus species are widely cultured around the world and considered an important cause of allergic reactions. in the present study, we developed a sandwich elisa to quantify pla or 3 allergen in p. orientalis pollen extracts grown near high-traffic roads and compared it to pollen extracts collected from rural areas as control. methods: pollen samples were collected from three pollu...

The present study used a quasi-experimental research method with pretest-posttest control group to show the effectiveness of Fernald’s multisensory and educational games on writing disorder in elementary school students. statistical population this consisted all students problems Shabestar 98-99 academic year who were studying. 30 people selected as sample (the first 10 experimental method, sec...

“broussonetia papyrifera” (chinese mulberry) pollen is an important source of allergens in regions surrounding shanghai, china. to identify and purify major allergens from “b. papyrifera” pollen that reacted with serum antibodies from sensitized patients, “b. papyrifera” pollen was defatted, dried, and extracted proteins were separated using sp cationic exchange or q anionic exchange columns. s...

 In this study, the palynology of 33 species of Silene belonging to 15 sections was investigated to examine the correspondence between palynology, morphological sections and phylogenetic trees. The pollen grains were prepared using the acetolysis method. Quantitative and qualitative micromorphological features of pollens were investigated using light microscopy and scanning electron microscopy....

in order to study stigma receptivity in peach cultivars : (‘makhmali’, ‘anjiri-ye-tabestane’, ‘anjiri-ye maleki’, ‘haj-kazemi’ and ’zoodras’) controlled pollination was done in both field and laboratory conditions. before pollination trials the in vitro germination of the pollen was tested in petridish. branches with adequate number of flowers were chosen for controlled pollination. self pollin...
