Self-incompatibility Studies of Some Iranian Late-Blooming Almonds and Pollen Source Effect on Some Characteristics of Nuts
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...
متن کاملXenia in Almonds: Pollen Source Effect on Characteristics of Some Iranian Late-Blooming Almonds and their self-Incompatibility
The objective of this experiment was evaluation of self-compatibility and identification, introduction and selection of late flowering genotypes as cultivars. This experiment was carried out in order to determine the best pollinator for two commercial almond cultivars, 'Shahrood 12' and 'Shahrood 21'. Applied pollinator cultivars were included pollen from 'Shahrood 21', 'Genco', 'Tuno', '5-15' ...
متن کاملThe determination of different effective concentration of ethanolic extract of bee pollen on biochemical analysis in liver, spleen and heart tissues of rainbow trout, Oncorhynchus mykiss (Walbaum, 1792)
The aim of this study was to investigate the effective concentration of ethanolic extract of bee pollen on liver, spleen and heart tissues of fish. Bee pollen extract in various concentrations (0.5, 2.5, 5, 10, 20 and 30 ppm) was administered to fish for 96 h under aquarium conditions. The malondialdehyde (MDA) levels, total antioxidant status (TAS), total oxidant status (TOS), oxidative stres...
متن کاملA revision of chestnut-leaved oak (Quercus castaneifolia C. A. Mey.; Fagaceae) in Hyrcanian Forests of Iran
Chestnut-leaved oak (Quercus castaneifolia C. A. Mey) is one of the most important native oaks of Iran distributed in the Hyrcanian Forests. The pure and mixed stands of it cover about 6.5% of these forests. The species represents morphological variations which have resulted in the description of several infraspecific taxa by different authors. Eight taxa were recognized as subspecies and varie...
متن کاملPollen texture identification using neural networks
The importance of research leading to the automation of pollen identification is briefly outlined. A new technique, neural network analysis, is briefly introduced, and then applied to the determination of light microscope images of pollen grains. The results are compared with some previously published statistical classifiers. Although both types of classifiers may work, the neural network is ap...
متن کاملEvaluation of cultivated and wild barley cultivars affinities using micro and macro-morphological traits of grain, pollen, and stomata. Sayyedh Masomeh Hosseini 1*, Mahlagh Ghorbanli 2 and Hossein Sabouri 3
In an ongoing research, 24 cultivated and wild cultivars of barley were evaluated for morphological characteristics of grain, pollen, and stomata. Traits of interest included length, width, and area. Results of variance analysis showed that all samples were differed in traits of stomata, grain, and pollen at probability levels of 1 and 5%, suggesting remarkable genetic variation among studied s...
