In order to evaluate eight different protein sources in honey bee nutrition, some experiments were conducted as a completely randomized designs with four replicates and three steps incubator, field and overwintering in Isfahan region. Protein sources were lentil flour, soybean flour, soybean meal, bread yeast, wheat gluten, skim milk powder, fish meal and Pollen. Results showed that the longevi...

abstract to study the effects of xenia and methaxenia on the pistachio nut, 4 male genotypes from among all male genotypes provided by rafsanjan pistachio research institute were selected. the flowering period of the chosen genotypes was the same as 3 female cultivars of kalleghoochi, ohadi, and ahmadaghaii. by using split plot in the form of completely randomized blocks design, we conducted va...

The objective of this experiment was to evaluate self-compatibility of two late blooming almond cultivars and identification and introduction of suitable pollinizers from late flowering genotypes, and evaluation of pollen source effect on fruit characteristics to earn high quality nuts for Iranian almond industry. This experiment was carried out in order to determine the best pollinizer for two...

Nonea Medik. is a genus of the Boraginaceae tribe Boragineae, with approximately 35 species worldwide. Examination of their palynological characters supported the separation of taxa, which is usually based on morphological and micromorphological reproductive features. Pollen grains of 10 taxa representing three groups of taxa in Iran, the N. caspica group, the N. persica group and the N. lutea ...

self-incompatibility is one of the most important difficulties in almond production which reduce fruit set dramatically.therefore, breeding almond to produce self-compatible genotypes is very important. in this research, pollen tube growth was studied in 28 genotypes obtained from crossing between touno (male parent) and shahrood 12 (female parent) after self pollination by fluorescent microsco...

studies of postmeiotic chromosomes have been impeded by the thick exine of immature pollen grains. chromosome staining of immature and adult pollen grains through conven-tional acetocarmine procedure is tedious and often leads to unsatisfactory results. an acetocarmine stain, used in conjugation with carnoy’s solution as fixative for 72 hrs or until the chlorophyll-containing tissues of spike b...

The effect of Persian bee propolis and pollen extracts on innate immune response of rainbow trout (Onchorhynchus mykiss) was investigated. Fish were fed diets containing 1% Pollen, 1% propolis and combination of the two immune-stimulants (0.5% Pollen and 0.5% propolis) as treatment groups and fed without the two immune-stimulants as positive and negative control groups for 4 weeks. The effects ...

The aim of this study was to determine the effects of different plant growth regulators, NAA (0 mg/l, 50 mg/l and 100 mg/l) and GA3 (0 mg/l, 50 mg/l and 100 mg/l), with various boron concentrations (0 mg/l, 50 mg/l and 100 mg/l) on pollen germination of ‘Şaba’, ‘Rabie’ and ‘Padre’ almond cultivars in 10% sucrose and 1% agar medium at 24°C in dark conditions. The results showed that different tr...
